	Hello I have a PFE29PSDESS I AM HAVING ISSUES with bottom drawer freezing. I have replaced the evaporator fan that works fine now .also replaced the damper fan. It still freezes up. I can c the EVAP fan working but I don't know if damper is. What else could be wrong? Do I need the defrost wire? And where is that. Thank you.

	Originally Posted by: Gene Ross, It would not surprise me if the new control board is defective. Try to exchange it under the part warranty. Gene. Thanks for all your help Gene. I checked thermisters & then put the fan motor back in and it's working perfectly. I'm guessing that there was a bad connection - the pins looked a bit corroded. For anyone with similar problems here is a link to some good info: http://www.geservicenet.com/cc/...rator_AC_Diagnostics.pdf

	OK - I checked the voltages and got 12V or so on red-white but nothing on yellow-white. I connected the motor wires to a 12V source (yellow & red to +, white to -) and it ran. The board is new and the motor was not shorted so unless the board was defective when I got it then it should be ok - right? I found a good document on GE Electronic Refrigerator Diagnostics but it does not describe the logic used by the board to control fans so I'm not sure where to look next - tonight I plan to check the thermisters. Any more sage advice would be appreciated. Ross PS I bought a new fridge so the pressure's off. I did run it for a few days by putting a small fan in place of the ev fan running continuously

	Check the voltage to the evaporator fan motor as described in one of our previous threads: http://forum.appliancepartspros...or-test-replacement.html Gene.

	Hi - I agree in hindsight. However, the motor has 1646 ohms w to r so its not shorted. No burned resistors on the old or new board. I applied 12v and it did nothing.

	For problems like an evaporator motor not running, I always recommend (for the motherboard refrigerators) to replace the motor AP3855880 and the motherboard at the same time. A bad fan motor will blow out the driver on the motherboard, so now you need to replace both items!

	Originally Posted by: BYmechanic Hi I have a GE profile PFS22MBS refrigerator which had been experiencing wide temperature fluctuations for a couple of weeks. On Tues the top fridge compartment went up to 74 and the freezer to 24. The fan was not running. I replaced the control board and the fan now runs and the freezer is down to 15 indicated - zero by thermometer at the very bottom - but the top fridge is still at 74. Any ideas what to do next? Besides go shopping, I mean I don' have a schematic or parts diagram. update - evaporator fan not running. don't know why
