#320748 Samsung WF218ANW/XAA drain problem

Posted by Samurai Appliance Repair Man on 25 May 2015 - 04:16 PM

Assuming there's free flow from the tub to the pump intake? Can verify by pouring a cup of water in the empty drum with the gookus-catcher out and see if the water flows right out. If that's the case...

 

Then either the pump is failing (common on Samsung washers) or there's something blocking the discharge hose/90 degree elbow. Either way, the sure fix is to replace the pump assembly. Part number: AP4564724

Also, gookus in the pressure dome. Remove hose from pressure switch and blow into it down toward the tub to clear any gookus (ie., detergent scum) that may be blocking the hose.

where is it getting frost build up. the back wall? the ice chute? around the ice maker? on the walls?

 

Some good questions for you to answer here. 




#320399 Amana SXD26VE fridge not cooling

Posted by Samurai Appliance Repair Man on 20 May 2015 - 08:11 AM

According to their own website, if you plug your model number into the compatibility checker on the part page linked in your post, it says that that relay is not compatible with your model. The one I linked to is.

#320306 lG FRIDGE LFX31945ST/01 AUGER MOTOR WILL NOT TURN AFTER NEW BOARD

Posted by Samurai Appliance Repair Man on 19 May 2015 - 11:45 AM

Good find, Brother Spanner!

I think what we're seeing in the pictorial is a classic case of "Korenglish." You are correct that they do not show a cube solenoid in the schematic and I don't think there is one. Rather, I think the pictorial contains a mis-type- the "cube solenoid" heading should read "cube winding."

But it does confirm a couple of things that I was speculating about on the auger motor. First, that the black wire is Line because it is common to both windings. We see this because the winding resistance measurements are taken black to gray and black to white, just like I speculated. Second, they give the spec for the motor windings: about 35 ohms instead of the 1K-ohm that I was guessing about.

I think we are seeing light at the end of the tunnel and have managed to piece together a sound troubleshooting strategy!


#320298 lG FRIDGE LFX31945ST/01 AUGER MOTOR WILL NOT TURN AFTER NEW BOARD

Posted by Samurai Appliance Repair Man on 19 May 2015 - 11:09 AM

Good thought on the capacitor, Brother Pduff.

I had another thought on the auger motor itself. That motor is supplied with three wires: black, gray, and white. Since it is an AC motor that is capable of changing directions of rotation, then this must mean that there are two separate run windings in the motor. If this is true, then the black wire is probably line voltage and the gray and white wires would be two different neutrals that are switched by the board.

So, for example, the board would close the neutral on the gray wire to cause current to flow from black to gray and make the motor turn clockwise. Similarly, the motor could close the neutral on the white wire to make current flow through that winding and make the motor turn counterclockwise. I'm just guessing about the directions of rotations and the associated neutral but you get the idea.

If this is the case, then what you may actually be hearing with the humming noise is both neutrals being switched closed at the same time. This would cause the motor to hum but not rotate.

One way you could test this would be to measure the resistance from black to gray and then again from black to white to see if you're measuring through the each motor winding. LG doesn't give us the specifications on those two different motor windings, but it's probably going to be something in the range of 1K-ohm. Whatever it is, the two windings will have about the same resistance.

You could then test the auger motor by hotwiring from black to gray and see if the motor turns. You could repeat this test for the black to white pair and see if the motor turns in the opposite direction.

Another test you could do would be to leave everything connected while energizing the motor. Then use a loading meter to check from black to gray and from black to white. Only one pair of those should light up for any given ice selection. If both black to gray and black to white light up on your loading meter, then you know that both neutrals are closed and this is the scenario that I was speculating on earlier: both neutrals closed resulting in both motor windings being energized at the same time and therefore resulting in the motor rotor being held stationary while the motor is making a humming noise.

Also, if all the foregoing theorizing is valid, then removing one of the neutral wires would not solve the problem because you would only have one direction of rotation on the motor resulting in only either crushed or cubed ice depending on which Neutral was removed. In fact, if you are seeing both pairs of wires, black to gray and black to white, lit up on your loading meter then this means that the dispenser board is defective.




#320291 lG FRIDGE LFX31945ST/01 AUGER MOTOR WILL NOT TURN AFTER NEW BOARD

Posted by Samurai Appliance Repair Man on 19 May 2015 - 09:27 AM

This gentleman said I have no idea what I am doing... 

 

He's an ass.

 

... and the main control board needs to be rewired. He told the homeowner that the dispenser uses a dual neutral control and you have to remove one of the neutral wires to work with the substituted main control board.   ??????? What????

 

 

This may be true (or some variation thereof) but, if it is, there's no way to tell that based on the schematic or any other technical information LG provides in their documentation for this model. I didn't find a service bulletin on this issue, either. Which leads me to believe that Mr. Ass may have gotten this juicy little tidbit from a training session for authorized servicers and LG hasn't gotten the word out to the broader tech community yet (eg., service bulletin). 

 

So it's not that you're technically deficient or "don't know what you're doing." This is a great illustration of a situation where the manufacturer has not provided enough specifications for us to do our jobs as technicians: determine whether or not the component or load in question is operating within those specifications. 




#320250 Miele DW G 658 / 858 Plus Filling with water then stops

Posted by Samurai Appliance Repair Man on 18 May 2015 - 06:27 PM

If it fills to the correct level then stops, listen for a hum from the circulation pump. Most likely a stuck pump on an older unit like that

Posted by Samurai Appliance Repair Man on 14 May 2015 - 07:19 AM

But wow, that was mean-spirited, Hollywood. 

.

.

.

... and hopefully without being ridiculed and treated with this level of condescension.

 

Let's not be a delicate little flower here! Hollywood was trying to point out how to make better use of the site. Nothing should be taken as condescending or mean-spritied in what applianceman said to you.

 

 

 

Or perhaps the confusion is because I am using a Canadian model number (as one does when in Canada)? 

 

How are we supposed to know that it you don't indicate that and even mislead us with your profile info?
