GE GSS20DBMB not staying cold in freezer or Ref side

13 posts in this topic

Went out on call for GE SxS m# GSS20DBMB with cooling problem.  Customer said that sometimes it worked, and sometimes it didn't.

I troubleshot the board.  Jumped the compressor to the points on the board and the compressor started right up.  All the fans were working when I got there, there was no evidence of a defrost problem.  The board was # WR55X10656.  It seems that there have been many problems with this board, so all of this led me to replace the board.  After I replaced board with new board part# WR55X10942, and plugged in the unit, the compressor, condensor fan, and evap fan all came on and the evap coils began to get cold.  I packed up and left.  Two days later, customer calls back with same no cooling problem.  Any thoughts?

Defective thermistors.

Probably on the evaporator.

After looking at the service manual, that is what I was thinking.  Any thoughts on why the compressor was not running but the fans were when I got there?

ALSO, did you follow the M/B installation steps ?

including Step 2

"ENCODER models with the following serial number

prefixes: TD2, VD2, ZD2, AF2, DF2, FF2, GF2, HF2,

LF2, MF2, RF2, SF2 . . . "

I saw the instructions you are referring to. The serial # started TA so I didn't change anything. I'm going back today to check thermistor.

Went back to check it out. Found all thermistors reading proper ohms. When I got there the unit was cooling properly with both fans running. I cleaned the condenser coil out better. I think the start relay could be faulty. I told the customer to call me in the morning with an update.

 I think the start relay could be faulty. 

 

 

These can be tricky to catch if they're on the way to failing but not quite dead yet.  Did you ohm between the pins for the compressor windings?  Should be something low and stay stable when you shake the relay while with your probes in the holes.

I did not ohm the compressor windings.  When I was there the third time, the compressor was working fine.  I had cold air in the freezer and the ice pack that was in there was frozen solid.  I still have not heard back from customer.  If she calls back saying it is still not working properly, I will check the the windings.  I found out yesterday that the ref. had been problematic for several weeks now.  I am wondering if the falty board caused a strain on the start relay. I still think the board was bad because on my first trip out, the compressor would not run unless I jumped the white to orange (line to compressor) on the board.  By looking at the posts on this site, it seems that the board in question has caused many problems to many people.

I had kinda the same issue customer said that it would not stay cold all the time ( cold warm cold warm ) changed board  but this did not help so I change all thermistors and no call back.

When you replaced the thermistors, did the ones you replaced check out ok?  I just had the customer call back today, a week after the last trip out and she is saying it is not working properly again.

Change the relay/overload/start capacitor. On bottom freezer models I will change the board which is clearly burnt

and somehow how the relay assy goes bad also. I've had to do it 3 times in the past two weeks. Weird.

While I'm saying that's definitely what's happening in this case, I have seen this exact failure cascade in a Kitchenaid refrigerator with the ADC board & mechanical cold control.  Can be very tricky to catch in the act.

I've seen the board and the start relays fail at the same time before on GE bottom mounts
