GE bottom freezer
« on: June 13, 2013, 12:26:05 PM »
I'm working on a GE refrigerator, MOD:PFS22SISBB, it's not cooling, so I checked the board and there was a huge burn spot so I switched it ou and the compressor still wouldn't kick on. The relay is good. I can't find the service manual it would really help if I could see a wiring diagram.

I tested the temp control board and it had no power it was completely dead. I'm getting power to the MCB. But nothing to the comp or Def coming from the board. Also I checked the 24volt connection at the J4 connector and Im getting 24V. At this point I'm stumped. Any Ideas?

May have a bad board.Did it blow any resistors that control the fans on the old board?

Yeah the board was bad there is a burn spot on it. And that resistor does look like its fried. When I plug it in I'm getting power to the new board and the lights are on but everything else is dead. The temp control inside is dead I took it out and plugged it into the J4 connector on the back of the fridge and it was still dead. I think the fan has shorted and the neutral is all connected at the fan so ther is no power. If I had the actual service manual It'll really help.

Couldn't find a manual for that,  maybe someone has it.   But I'm thinking fan sounds probable.   I've had several GE fridge's that had the fan short and take out the board.    That is where I'd be looking myself.   I always carry a condensor and evap fan (the one with the thermistor on board)  so I would have just switched it out.

Would that also cause the control board on the inside of the fridge to fail? Or not to display anything.

If you put a new board in leave the J2 plug unplug and see if the compressor comes on and the front user face lights up.This will keep all fans off then go from there.If its comes on more then likely a bad evaporator fan motor.Looks like that cost some money if is that fan motor.G.E for you.

I got a headache with this stupid fridge. I put a brand new control board and condenser fan, and it did absolutely nothing. The problem is that everything that uses dc voltage isn't working. The valves work fine and when I jumped the compressor it worked fine but the fans don't work and the control voltage for the compressor doesn't work either. I'm stumped I hate this f**king fridge( sorry for my French AJ) with all the work that goes into these things I might as well just work on commercial equipment it'll be way more money.

I know on some of those ge fridges there are some other modifications that need to be done as well. Dont have the tech sheet with me, but i have had to modify some things before. Its not always as simple as plugging in the board. Make sure you check the model number against those listed on tech sheet

Yea i think he was talking about the instruction sheet with the serial numbers to correct if it apples to your serial number.I know from my parts look up that the original board was part # WR55x10526 and change to WR55x10942 so you could have to do something to new board if it has one of those serial # on the Sheet.May want to look at that.

Yea i read somewhere if you leave J2 off when you install new board that would off coarse keep all fans off but suppose to fire up compressor at least.Never tried it though.I don't know what to tell you.Bottom mount is a bitch to get to that evap. fan motor if it is bad.Sometimes you can have the you wish you never got involve with.
