I probably have a hundred fridges that are still on that list. My GE rep sends me boards just on an e-mail.

My city has a city-wide trash pickup day where people haul things to the curb and the city comes and picks it up to haul off to the dump. I discovered an abandoned partially parted out a GE refrigerator. Someone took the doors, but I got the auger, auger motor, ice maker/feeler assembly and ice container, door switches, temperature control knobs, solenoids and motherboard.

I'm glad to have found schematics for wiring the motherboard to the motors for use in other projects, but I don't see much for inputs aside from J4. how can I activate the relays for k1 k2 and k3 without the (now missing) door panel?

I have this control board and I have found my problem. The connector j8(compressor) burned up just after the connection on the board. Where does the j8 connect on the board?

Rick, can you please give me advice on my fridge?

I have a PFE28RSHCSS.  It is a bottom freezer, french door GE profile fridge and it is only a year and a half old.
The bottom freezer works fine, but the fridge is warm.  There was also water and ice in the deli drawer.  I replaced the thermister and the defrost thermometer and it still didn't fix it.

I then noticed that both fans; the deli fresh food fan and the (i think its called) evaporator fan, in the main fridge compartment are not working.  I checked the circuit board and the resisters look fine.

Would you recommend that I change both fans and the circuit board?
side note- we did have some power outages here about a week prior.  I wonder if something got messed up with the power coming on and off.

I'd get warranty service on it. Here's a thread that details your problem: http://appliancejunk.com/forums/index.php?topic=20346.0

I ended up doing a software update and replacing the FF fan.  Works now!

REPLACING EVAPORATOR FAN MOTOR AND MOTHERBOARD ON GE SXS REFRIGERATORS

Does this apply also to condenser fan motor I have one that the fan do not work !!!!!!!!?????????



This is a rewrite of a thread I started in 2011 in an attempt to make it easier to understand how to determine whether the evaporator fan motor should also be replaced with the motherboard on GE refrigerators with failed motherboards.

Iíve had to replace both the variable speed DC evaporator fan motor along with main control boards or ďmotherboardsĒ on GE side by side refrigerators, mostly the GSS HSS and PSS 20-22-25-27 cubic ft. models with both metal and plastic liners. Iíve found around half of these board failures were partly due to a faulty/shorted DC evaporator fan motor.


Moisture gets inside the fan motor or thermistor thatís attached to the fan motor and causes shorts in the motor.


Replacing just the motherboard and not the fan motor will only result in another failed motherboard in a short amount of time.


To determine whether or not the fan motor should be replaced with the motherboard, first look at the two resistors below the J2 connector.
If they are burned or discolored you should replace the fan motor.


Remove the J2 connector and check the resistance in the harness between the J2-3 white wire and J2-8 red wire. There should be approximately 1.5K to 3.0K Ohms. If it reads open or shorted you should recheck it at the motor. If the readings are the same replace the fan motor.


On the mother board, check for 13 VDC between J2-3 and J2-8 and check for between 8-13 VDC between J2-3 and J2-4.
When no voltage is measured at the motherboard check for a short in the fan motor between the yellow and white wire and the red and white wire. A short in the fan motor will damage the motherboard.


If either of the following symptoms exists, freezer section thawing and refreezing, fan motor speed erratic or makes noise, or water stains and/or rust on the fan motor, then I would recommend you replace the fan motor.


While replacing the motherboard on GE refrigerators is common on all models, I have not seen this particular problem on top mount, bottom mount, french door, or inverter models.


Iíve marked the image and picture of a failed motherboard for easy reference.
