I too am having problems with this fridge.
I bought it in April 2004.
Then in July 2006 I found the fridge & freezer very warm and all food spoiled.
I pulled the power from the fridge for 20min. I plugged it back in and I heard it turn on. But the fridge/freezer would not chill.
SEARS came by and put in a new circuit board.
Everything seemed fine.
Freezer-0, Fridge-37 (Temps seemed stable).
I should note that SEARS showed up with a new main board (P/N: WR55X10416) and an instruction manual that informs the technician to cut wire #2 from Terminal/Connector "J1". Apparently this wire is connected to a thermistor.
This instruction sheet also said to cut the ground wire from the compressor harness. This new board came with new earth ground connections.
Which my old board didn't have.
I'm guessing this grounding rewire is related to inductive noise from the compressor?
Oh..my old board number was WR55X10339
So now it's April 2008 and I'm finding my temps are riding low and high, and opposite to each other. So, if my fridge is warm, then my freezer is colder.
For example.. (Defaults are 37F & 0F)
Freezer -3F and fridge 42F
Freezer 1F and fridge 33F
SEARS comes back.
We find that the condensor fan isn't spinning and the compressor is quite warm. SEARS orders a FAN & Main-Board and says they will return in 3 days.
In the meantime I put the old board in and right away the compressor kicks in and the fan starts. I examine the board and find the processor pin that drives the sinking transistor for the fan. Its a square wave at roughly 1khz, 10% on, 90% off.
So I put the second board back in (Which is the most recent board).
I lift the fan pin at the processor and feed in a square wave signal from my fun-gen. Fan is now on. After a couple of hours, the fridge temps are better.
SEARS returns and is a little surprised to find my fun-gen tapped into the main board. I should admit I am a Controls Eng and I design Controls systems. I design and layout circuit boards as well.
SEARS is also glad to know the fan is working.
The fan is $239.99 (WR84X10055)
So only a new board was needed. $174.99 (WR55X10552).
Now I have a new (3rd) board and temps still seem to floating around quite a bit. But I have yet to go grocery shopping, so my fridge is only 30% full. My freezer is about 30% as well.
I can hear the fridge do it's gurgling thing
every so often.
And it makes that sucking sound after I shut the door.
But the fan is always running?? Should it be?
I don't mean the compressor fan, I mean the one you hear inside the fridge.
I don't recall it always running before?
If anyone has this fridge.....does this fan run all the time for you?
Now my fridge is reading 1F and 33F.
In regards to cutting this wire at J1.
Should this have been done? The installation sheet says this should be done for
all "Encoder Models with the following serial numbers..................."
My fridges serial starts with AR
and is NOT in the list...
