      [Webinar] Appliantology Workshop   11/09/2017

      Information is the name of the game in the appliance repair trade today. Appliantology is a powerful information tool for the professional appliance repair technician. But just like with any of the more capable tools in your tool bag, many of the more powerful features are hidden from you unless you "read the manual." Ugh! Who wants to do that? Well, this is one time when you don't have to! In this webinar, Team Samurai will personally walk you through the site and show you many of the useful and powerful features that even long-time users probably never knew existed.

New Fridge - Looking for ones like Samsung with split fridge/freezer

Recommended Posts

EricEE

Other than combing through often incomplete documentation, is there any list or shopping tool that anyone knows of that can show if there are other fridge/freezers out there like Samsung that have completely isolated freezer/fridge compartments?

I had a Samsung at my previous house and I really liked it and the isolated, compartment-specific cooling. Funky flavors didn't migrate from the fridge into the freezer, and food really did last longer in the fridge - especially veggies. Supposedly some models in other brands like some GE Artica models have isolated compartments, but it's often impossible to verify other than either tearing it apart or getting lucky and finding the service manual and analyzing the breakout diagrams to ensure their is no linkage between the fridge/freezer.

I'm hoping there's an easier way :whistling: And if Samsung is it, I'm not opposed to them - my last Samsung was great and I was very happy with it, but since I'm possibly going to need a new fridge soon I figure I might as well do a little research first.

Thanks!

I would not have a Samsung appliance in my house even if I got it for free. Their refrigerators are trouble prone and they make them more complicated then they have to be.

Six year old GE Artica PSS26NGPC - looks like it has fallen prey to the well-known motherboard issues - whether it's just the motherboard or the motherboard because of a fan short, I haven't verified yet. I think I'm going to break out the multimeter and run through the diagnostics to confirm. I'm still on the fence about fixing it since the problem will probably just resurface - it's pretty obvious there is a serious design fault in the motherboard :yucky:

Thanks for the feedback on Samsung. Like I said I had one for a couple of years before and didn't have issues, but it's in the five-year plus range where problems tend to develop. It's so hard reading online to detect real issues vs. people just complaining - i.e. the only time you typically get feedback is when something goes wrong! I know that first hand having been in the IT industry for over 20 years and doing end user support for the majority of those years.

My problem is I know most new stuff is manufactured to similar "quality" standards due to competition, so it's probably unrealistic to expect 10 year+ trouble-free service like the "old days". With energy star, electronics and other complicating factors I fear it's just to be expected these days. Ugh...

Thanks for the LG link! I prefer the interior layout and ice cube shape on the LG - and I searched around trying to find out if they had a dual evaporator. That's awesome! I'll also look up that Frigidaire.

Thanks again guys!

PSS26NGPC

depending on the first (2) characters of the serial number,

there may be a service bulletin about the MotherBoard and Evaporator Fan replacement / recall

The replacement Motherboards have been re-designed

also, from the LG link above:

" ... while the Linear Compressor and Dual Evaporator keep humidity and temperature at the perfect setting."

I already called GE and my serial number is not in the range (starts with AH). Reading round on the web some people have got GE to replace it anyway so I figured what the heck. While the person on the phone was nice, no dice :(

It's good to know the motherboards are re-designed. I guess I'll test the fans to make sure there are no shorts, and if that's the only problem I see a new motherboard in my future. While I loathe this side by side, a couple hundred vs almost $3K is still an easy decision :woot:

also, from the LG link above: " ... while the Linear Compressor and Dual Evaporator keep humidity and temperature at the perfect setting."

Yup! That's the ONLY page on the LG site that I have seen the Dual Evaporator touted. Even the tech specs and tech sheet don't mention it! Talk about failing at marketing - I realize most people don't even know what an evaporator is, but sheesh - a competitor is translating it into marketing speak - you think they could too!

Thanks again for the heads up guys!

Too funny - I did a quick search to find some tips for checking for DC motor shorts and if I included Fridge in my search terms GE came up every time :yucky:

So looking at this list and with my serial number starting with AH, I probably have the earlier motherboard and a new one will definitely be the redesigned one so chances of this problem re-occuring will be as minimal as can be expected?

I'd hate to have a newer one and already have the re-designed board!

earlier MotherBoards didn't normally have those problems ...

it was the "intermediate" MBs that were a problem... the "redesigned" MBs may just be that they went back to the "earliest" design

Is your Evaporator Fan good ?

Is your Evaporator Fan good ?

Signs point to no. The resistance is off and it's got a mountain of rust. Good news - without the fan harness (J2) plugged in I do get 12 volts on pins 3 and 8, and 000 is flashing on the temperature display which would hint at self diagnostics? It doesn't respond to any keypad presses - I'm hoping that it's just freaking out because J2 is unplugged. I'm going to order the motherboard too since they tend to go hand in hand but maybe I'll get lucky?

If I replace the fan and plug it into the original motherboard, if the motherboard is bad it won't fry the new fan right? So far it seems only the fan is capable of frying the motherboard but I just want to make sure it can't work the other way too.

Thanks for your help! Time to order parts :yucky:

Replaced fan - no dice, display still acting funky. Oh well! Replaced motherboard, put freezer back together, plugged in - compressor starts!

Blowing cold air!

Woo hoo! Now that it works, I guess I'll clean it out really good before putting it back in it's home and setting it to chill down.

Thanks everyone! $200 was definitely cheaper than $2800 - no matter how much I would have loved to justify getting a freezer on the bottom :rocker:

EDIT: Also got my subscription - well worth it! Wondered why I couldn't reply in all the forums :sillytongue:

I'm glad you repaired it rather than breaking down and giving Korea $2800 for a new over engineered refrigerator.
