Remove the upper grill and look for an envelope with the tech sheets. Perform the teats as described there and post the results.

Gene,

I appreciate the knowledge you have shared on this topic, and it has been useful to me. However, I'm still experiencing the same problem. I have a GE side-by-side model GSH25JSTA SS. Several months ago, I noticed that the fridge side was 50 degrees + even though the freezer was working properly. After finding your message, I determined that the coils were frozen so I thawed them and hope for the best. To make a long story short, based on continuity tests it seemed as if the motherboard was not working correctly, so I replaced it with a new one from my local GE parts supply. To my surprise, the problem returned within 2 weeks. So, even though I thought they tested okay, I replaced the thermostate and heating element about 10 days ago. Well, today my fridge was 50 degrees + again and the coils in the freezer where heavily frosted over.

The only thing that I noticed this time is a loose grounding wire at the bottom of the freezer. I was aware of one located at the top of the freezer that connects to the dividing panel, but this is the first time I saw the one at the bottom. I connected it, but I don't know if it will make a difference or not.

Given the above, do you have any insight as to what my problem might be now? If I have a second faulty MB, how do I specifically test it to prove that it is faulty so that I can exchange it (I tried to follow your directions as posted, but I may be a little unclear as to exactly which leads I should be testing)?

I would suspect the evaporator thermistor (on top of the evaporator).

- The thermistor Part number: AP3185407

Aren't there 2 of these in the freezer (1 at the top & one at the bottom)? Should I go ahead and replace both (are they the same part #)? BTW, what is a thermistor?

[Gene]

I meant the top one. I do not think you have to replace both of them, but it's not going to make it worse if you'll do it. Both of them are identical.

Thermistor is a temperature sensor which changes resistance when temperature changes. The main control board monitors its value and operates with defrost cycle.

They were cheap enough so I picked up 2 at lunch today from my local parts supplier. What is the best/easiest way to monitor proper operation apart from waiting until everything freezes over? Should I just visually check manually, or is there any way to force a defrost cycle to observe the system in action?

[Gene]

You can force the defrost cycle by bypassing wires at the main control board, but I personally do not like it. I would let it work and just monitor it. As you described in the first post, two weeks should be enough to see how it works.

Hi Gene,
I have a Kenmore side by side refridgerator, 106.53606200.
The problem happend this morning, the fridger is not cold enough. There is no problem with a freezer. There is no food blocking the air vent in both sides, but the cold air doesn't come out into fridger. Can you help me what to do?

Thanks in advance.

[Gene]

Check if the fan in the freezer works. If it does then replace the air diffuser (in the upper left corner in the fresh food compartment).

- The air diffuser Part number: AP3084126

I have a GE TFX22KRDAWW a few weeks ago the fresh food side got warm. I opened the panel in the freezer section and it was a block of ice on the coils. Defrosted and also did a through cleaning of all dust around fridge. It has worked for several days and now same problem. Looking at the parts list I don't see a listing for a defrost timer for this fridge. There is a listing for a defrost heater assembly. I am thinking of going ahead and getting and replacing this. They also list a redsigned assembly, but not sure if that will fit or not. Any suggestions if I am going in the right direction.
