Dielectric Grease: Myths and Reality


There's a lot of misinformation and mythology out there in the tech community about the use of dielectric grease on electrical connections. Some techs, knowing that the word "dielectric" refers to an electrically insulating material, mistakenly conclude that dielectric grease should never be used on electrical connections. This is based on a misunderstanding about how dielectric grease works.

Dielectric grease has two main properties that make it especially desirable specifically for use on electrical connections, especially in wet environments such as refrigerators and washing machines. In fact, this is its primary intended design use. Those properties are:

1. Low viscosity. This means that the grease will readily get out of the way of two metal contacts touching each other and flow around the contacts giving rise to the second desirable properly...

2. Sealant effect. As the dielectric grease flows around the contacts, it seals out moisture and oxygen preventing them from reaching the contacts and causing corrosion and/or oxidation.

Still don't believe me? How about Frigidaire tech bulletin RF1207:

Recommendation for Use of Dielectric Grease on French Door Models with Bullet-Style FFIM (RF1207)

Water intrusion into electrical connections within the FFIM causes intermittent interruption of ice production and melting of ice in the bin.

Symptoms: No ice in FF
Ice melting in the ice bin while FFIM is
turned on

Models Affected: All ICON, Electrolux and Frigidaire models with Bullet-Style FFIM

Solution: Use dielectric grease Part number: 5304485963

Part number: 5304485963

to improve electrical connections inside the FFIM. Application is recommended on EEV, TH3, TH1 and fan connectors, however it can also be used on any connector within the FFIM assembly. In general, if all diagnostics pass and the unit has 8.1/8.5 FFIM board yet the unit is either not producing or not maintaining ice, water intrusion into electrical connection can be suspected and dielectric grease may resolve the problem.

Father's Day 2015 and my washer breaks.

Posted by TheApplianceTechnician in TheApplianceTechnician's Blog, 21 June 2015 · 178 views

So today's my day off, not just any ol Sunday off though. It's THE day off, father's day 2015. Today I'm supposed to relax, bbq some steaks on the egg, watch the kids play in the pool, have a few or 15 beers and go to sleep full and happy. Well if you've ever heard of this guy named Murphy it turns out he's a real asshole. I've been chuckling to myself for about 30 minutes now thinking of how much more ironic can you get. The appliance man's appliance broke, ON FATHERS DAY!

And we're not talking about a belt here. As you can see we're talking catastrophic failure.

I Was having trouble with the vid attachment so here's the you tube clip.



Old writing class paper/story

Posted by acfixerdude in acfixerdude's Blog, 19 June 2015 · 206 views

It was during the first break of day in the middle of a heat wave when we first received the call. A villager had requested assistance with a situation he could no longer contain. He and his family had been attacked by a once well behaved friend taking residence inside their home. This well-behaved friend had turned into a villainous foe, terrorizing the family by destroying their stockpiles of sustenance when least expected, an action which severely disrupted the family’s daily routine. They called upon us to fend off this rebellious foe and to restore civility back into their home.

So with a brave heart I prepared for impending battle. With my heavy weapons strapped to my side and only experience to guide me, I journeyed to the residence in need. When I arrived I was greeted by the saddened man and his family, begging me to tame the beast that ailed them. As I stepped into the arena of battle a sinister smell caught me off guard. The smell of burning copper singed my nostrils as I made my way towards the beast’s lair. It seemed to be annoyed by my presence and howled in anger. A great battle emerged as the two newly made arch-enemies began their attacks. Though the beast was a respectable foe, I took swift, fearless action and it was quickly and easily defeated. I had tamed the beast back into a domesticated pet, doing only as it was originally intended to do.

In order to prevent such rebellion and travesty in the future, I trained the villager on how to properly discipline and care for the now domesticated beast. I left him with the knowledge and the proper tools to keep his family’s stockpiles of food from ever being destroyed again. The villager and his family were eternally grateful and he practically offered his oldest daughter’s hand in marriage as a token of appreciation. As I left his home victorious, I only hoped he’d pay heed to my instructions.


Was this some sort of animal you ask? I would only tend to describe it as an animal when misbehaving, but no, it was not. Everybody has one of these often friendly devices and the same thing can happen to you and your family if you fail to take notice and learn the necessary information that this young villager learned the hard way. In fact, there are many friendly devices in your home that require tender loving care every so often. If left unattended to for too long it is very possible that they will turn on you and the situation can get very ugly; even uglier than the story I just told you.


So what was it living in this nice family’s home that turned so villainous and destroyed all of their food? It was that which was originally supposed to keep their food safe from spoilage, insects and other hungry animals; their refrigerator. If you’re not careful, it may happen to you too.

The Alliance of Appliantology!

Posted by Smashycomman in Smashycomman's Blog, 19 June 2015 · 412 views

LONG AGO IN A DISTANT LAND..

The people were happy. They had not a care in the world. They thought their beloved appliances would always behave. They woke up in the morning to the quiet hum of refrigerators, keeping their daily meals nice and fresh. They used washers and dryers to clean clothes to pristine condition. They used the microwaves to heat their food quickly and efficiently. They thought the appliances would always be there for them, always making their lives easier.

.....They thought wrong.

Suddenly, one day, as if from nowhere, the appliances attacked!

The Washer began spewing water all over their beautiful laundry rooms:
Washer


The Dryer began spitting fire and smoke everywhere:
Dryer


Microwaves took to the skies, shocking the citizens in horrible flocks:

Micros


Fridges stopped cooling the food, turning it into gookus, and then spewed noxious odors into everyone's faces:

Fridge



"OH THE HUMANITY! IS THERE NO ONE TO SAVE US?! IS THERE NO ONE WITH THE SKILL TO STOP THESE EVIL MACHINES?!", the citizens cried!

Have no fear, good people! Your heroes are here!

Introducing....

The Alliance of Appliantology

"Fighting atrocious appliances with aptitude!"


This Troop of Techs scour the land, searching for any disobedient appliance, doing battle with them, and turning them back into the good machines they were made to be!




First up, we have the Appliance Technician himself, Walter:

Walter


Walter is a monkey. His weapon is a katana, mixed with a flashlight. Good for slashing and scaring off those appliance monsters who are afraid of the light.



Next is Weswayne, or just Wayne:

Wayne


Wayne is a seahorse, wielding a screwdriver-shooting crossbow. Nothing wrong with a ranged weapon!


Here's Scottthewolf, or more appropriately, Scott the Lion:


Scott The Lion


Scott is smartly using meter leads, one of a tech's most powerful tools, he's using them as axes, but I guess that gets the job done!


Here's some guy named Smashycomman, or just Smashy if you're confused on what a "comman" is:


Smashy


He uses a giant screwdriver as a warhammer. There's a better use for that, kid!


Don't forget about DanInKansas, or maybe just Dan:

Dan


Dan is a beaver, who uses a shield and spear with pliers on the end. Stick 'em with the pokey end!


Last, but certainly not least, is our very own DurhamAppliance, who's gonna go by the very serious name of Durham:


Durham


Durham is the highest-ranking member of the group so far. Yes, he's a pink unicorn, but don't let that make you think he won't smack yer teeth out with his mages' staff.


Our citizens are saved! With their incredible knowledge of the inner-workings of these dastardly monsters, the Alliance of Appliantology takes them down one-by-one, turning them back into the hard-working and wonderful machines they should be. The citizens are very thankful! The day is saved!


Want to be in the Alliance? Here's one way: BEGIN YOUR TRAINING





Ok, so, I decided to do this after making a "What animal would you be?" thread on the 40-watt club sub-forum. What started as just a dumb question got me thinking about how fun it would be to actually draw these guys as these animals... then one thing lead to another and here we are. This took about 2 months or so. Having a kid makes it so you really don't have much time anymore! Anyway, hope you guys like it!

Tenacity when it does not make sense

Posted by Patricio in Patricio's Blog, 08 June 2015 · 333 views
VMW, Cabrio washer

Sometimes after all the diagnostics it still does not make sense. Case in point.

Worked on an Kenmore style VMW where complaint was dead machine. Initial observation machine just sat there blinking sensing light. Put machine into Error diagnostics where Error code was F7-E5 shifter fault.

Next step put unit into manual diagnostics. Spin & agitate cycle lights blink along with lid lock red light but nothing else happens. Dead machine that blinks at me. performed TEST#3a & 3b tests according to book. Resistance was out of parameters. while I was at it I checked voltages from control board with connectors connected. Correct power coming out of control board so board should be good. Tilted machine back, inspected harness wiring, no breaks found. Replaced shift actuator.

Attached Image

Next step I did was to perform calibration cycle. Calibration cycle would not finish blinking lights again, So I checked parameters at main board everything was good. Put machine into manual diagnostics, Agitate cycle would work in one direction only. Spin cycle would not work, lights blink. OK older machines agitate would only go in one direction during the test cycle. Did not believe this was the case unit only 3 years old.

Flipped machine back again to inspect harness again, nothing out of ordinary. Decided to to a test on the capacitor. Rated 45 microfarads showing only 27 on meter. Determined capacitor out of tolerance also. Replaced capacitor, reentered test mode, Machine agitated both directions in both gentle & heavy agitation. Making head way YES.

Next performed Spin cycle test. got a few revolutions & as basket ramped up speed machine died blinking lights at me again. Locked machine again. What next. Performed UI & tachometer test while I gathered my thoughts reforming strategy what to do next. Can't be lid lock latch. It locks/unlocks at all times in test mode, stays locked & performs agitate mode no problem now. Shifts into spin mode starts to spin then quits & blinks. Have to unplug each time to reset machine.

What do I do know now. Two problems taken care of shift actuator & capacitor. Can it be the control board, don't think so, power in power out, What gives, got to examine wiring & connections more scrupulously which leads to the dreaded wiring continuity checks from one end to the other.

Tilt machine back to wall again Lay on my mat & look & think, should I quit now & be beat, say a little prayer. No I don't give up saying: Posted Image


As I peer at the entrails of this POS called a washing machine I notice a whit object in the bowels of this machine. I reach into this small crevice

Attached Image

And pull this object out slowly as it unravels off the transmission shaft.

Attached Image .

Stand machine up put back into manual diagnostic mode & machine performs like it is off the assembly line.

After performing the diagnostic test, replacing corrupt parts I did not give up & condemn the machine citing to expensive to repair ie. new control board. Other things I did that I have not related but the point is I stuck with it giving my all to getting the problem solved. I hope this article helps to inspire others to be tenacious as possible to get the job done.

How to find documentation for Kenmore Refrigerators

Posted by DurhamAppliance in DurhamAppliance's Blog, 15 May 2015 · 470 views

Finding documentation for Kenmore appliances can be challenging at times. If you are lucky, you may locate it in our download section. When searching, try searching with the decimal, without the decimal, removing the decimal and numbers in front of it and replace them with an "*" while also replacing the last few letters with an "*". See Searching for technical documents http://appliantology...appliantology/.

But usually, Kenmore's are a pita to find info. You have to somehow cross reference the model to the manufactures compatible model.

Sometimes if you find the part number for the mainboard or user interface, you can cross reference the part to a model where the documentation is easier to find. Some manufacturers do make it easy. For instance

Frigidaire made Kenmores ... just look it up on Frigidaire's site but you must include the decimal.You will get a tech sheet but to find a full manual, check out my Frigidaire survival kit blog http://appliantology...r-survival-kit/

LG is also easy.. just use the first five digits after the decimal and look it up on LG's tech assist site.

Whirlpool made? Good luck with that....

Samsung? . well....


look up the model at Searspartsdirect... try to cross reference the mainboard using appliance parts pros (full site) ... but it only brings up other Kenmore models...damn... that means we got to do our own cross-referencing. so let's play Sherlock Holmes....

While we are already looking at it, let's grab a screenshot of the mainboard to compare with other samsung models.

On Sears, you see this fridge is a sxs..

Samsung refrigerator model numbers start with R (Refrigerator)then an S for sxs or f (french door) b (bottom mount) M (four door... maybe it may stand for Multiple door but I call them Mutha@#&fs!)

So far we have RS

If it has a three way valve then the next letter will be a G otherwise a number. So let's check out the machine compartment on the Sears' diagram and we see a 3 way stepper valve ... great! This means there are only a couple of Samsung models to compare boards with.

So far we have RSG

Check my Dropbox or Appliantology's library for models beginning with RSG (use wildcard search "rsg*")

And there are two models...let's look at the fast track for the first one... model RSG257AA .... hmmm.. i dunno.... they look sort of different... well the pictures' orientation are different... color seems off... but examining them closely... counting connectors... ah ha! it's the same board. There you have it cross referenced to an RSG257AA. Elementary, my dear Watson... uh... Bro. Patricio

Now , I did not spend all this time and trouble so I could ask you out on a date. Copy this post for future reference 'cause next time you have a Kenmore - Samsung fridge cross reference manual request and you don't attempt to obtain it yourself first and I have to go through all this again... well, we know how that's gonna turn out... lol

How to test motor speeds (RPM)

Posted by tpoindexter in tpoindexter's Blog, 13 May 2015 · 449 views
RPM, speed, How fast

I was talking with another tech this morning about checking RPM. this brought up the subject of strobes. As we were
discussing strobes it occurred to me someone had probably created an app with RPM already. Shazaaam!!! :woot:

Here's a app that will allow you to test RPM on fans. You can also test motor rpm, if, you place a mark on the shaft.
https://itunes.apple...d708094321?mt=8

To check fan speed just dial it in till the fan appears to be not moving at all. That'll give you your RPM.
Same with a motor if you mark the shaft. When the mark appears to no longer be moving you've got the RPM.

I'm not really sure if this is the correct use of this Blog thingy, but, bet I'll find out sure enough!! Yeeehaw!!!

Huh... I hope I wasn't the last person on earth to figure this out!

The Anatomy of a Miele dishwasher Waterproof System

Posted by LI-NY Tech in LI-NY Tech's Blog, 30 April 2015 · 464 views

Miele produces the best dishwashers on the market today. They are high end machines...very quiet, they wash well and last many years beyond the life span of a lesser quality brand. However, like all machines they do break down. One of the most common failures to occur on a Miele dishwasher is the Water Proof System (WPS). That's that mysterious grey box under your sink. What is that thing?

Posted Image

The WPS is a dual water inlet valve. The redundancy ensures that if one valve fails to close the other will, greatly reducing the chance of flooding your kitchen. That brass part on the left attaches to the house plumbing, the box contains the two solenoids and the gray tube contains the water intake hose, the wiring and outer sleeve. When the electronic calls for water the solenoids open and the water flows through the intake hose and into the dishwasher.

The outer sleeve acts a protection against leaks. If the solenoids leak the water will flow along the outer sleeve and into the drip tray in the base of the dishwasher. When enough water accumulates the float switch will be activated and the water intake will stop. The drain pump will also be activated until the machine is unplugged or the water is no longer present in the drip tray.

Posted Image


The inlet to the WPS contains a filter and a restrictor. The filter stops large debris from entering the system and the restrictor ensures correct water pressure. The filters often get clogged and can be easily cleaned.

Posted ImagePosted ImagePosted ImagePosted Image


The Miele dishwasher service manual states:

The WaterProof System (WPS) consists of a number of interdependent safety features to provide protection against water leakage.
1. Protection against solenoid valve leakage: Each water intake is controlled by an inlet valve. If this valve cannot close properly due to some defect or blockage by a foreign object, a second inlet valve ensures that the water supply is shut off.
2. Protection against water intake hose leakage: If a leakage occurs, water flows along an outer hose sleeve surrounding the intake hose to the drip pan. Here a float switch then acts to switch off a microswitch which closes the inlet valves to cut off the water supply.

3. Protection against dishwasher overflow: If some defect has caused the water level in the appliance to rise so that it overflows into the drip pan, and the water quantity sensor has also failed, the float switch is activated. This switches off a microswitch which closes the inlet valves to cut off the water supply. At the same time the drain pump is activated.
4. Protection against drain pump failure or blocked drain path: In this case the water level in the appliance rises until it overflows into the drip pan where the float switch is activated. This switches off a microswitch which closes the inlet valves to cut off the water supply.

Part deception

Posted by MicaBay in MicaBay's Semi Knowlegable Blog, 21 April 2015 · 456 views
part not what it seems

Recently, I needed to put two infinite burner switches in a Frigidaire slide in range. These switches were for the two large burners. Installed them, and did the simple but basic tests. Both burners now working, customer is happy, :blinky: , I'm happy. I collect my beer :pint1: money for the day and off to other adventures.

Customer calls back next day and not so happy. One burner doesn't get hot enough to hardly boil water. Okay I said, see you later today? Yes. Get out to location and here is what I discovered.... see the pictures below.

Posted Image

Posted Image

Did you see it? I almost didn't. Of course the story above is highly plausable but totally fake, because, I saw it before installation of said part. Moral is, always inspect your parts before installing them. One of the switches must have fallen off the assembly line and been packaged with the wrong part number... At the Factory!! Say it aint so, a manufacture making a part mistake?!!? :woot: :woot:

Coconut Lime Chicken Soup

Posted by Mrs. Samurai in Mrs. Samurai's Kitchen, 10 November 2013 · 1,341 views

Here's a Thai-inspired chicken soup that is easy to make and bursting with flavor! It's healthy comfort food with an Asian twist.

Posted Image
Ingredients
  • 2 tablespoons coconut oil, ghee, or butter
  • 1 onion, chopped
  • 1-2 pounds uncooked chicken breast, diced
  • 1 inch piece of fresh ginger, peeled and chopped fine
  • 4 cloves garlic, minced, divided
  • 1 quart chicken broth (I use either homemade or a box of low sodium, no added MSG.)
  • 1 can coconut milk (look for this in the Asian/Thai section of the grocery store. I prefer regular, not "lite".)
  • 1 lime, juiced, divided
  • ¼ tsp. red pepper flakes
  • 4 scallions, chopped
  • ½ bunch cilantro, chopped
  • salt, to taste
  • optional: Thai fish sauce, cooked rice
Directions

Heat a soup pot over medium high heat, then add the coconut oil. Saute the onions with a little salt for a few minutes, then add the chicken chunks with a little more salt. Cook, stirring frequently, until chicken is just cooked through. Add the ginger and half of the garlic towards the end of this.

Stir in the broth and bring to a boil, then stir in the coconut milk, half of the lime juice, and the red pepper flakes. Reduce the heat to low and simmer covered for at least 15 minutes (longer is fine, too).

Turn off the heat, and add salt to taste (depends on the amount in your chicken broth). Stir in the rest of the garlic, the scallions, and most of the cilantro (leave a little aside for topping individual bowls). Add the rest of the lime juice if desired. Cover and let sit off-heat for 5 to 10 minutes, then serve.

Great served over rice. Add a few drops of fish sauce to your serving to knock the flavor out of the park!
