GE Window Air Conditioner ASW12AAS1 PWB Schematic Available?

[ABreese]

Unit is approx 7-9 years old, in storage for 6 years, excellent condition.  Worked when stored.  Other general info:  capacitor is OK (replaced w/known good to check), overload protector also OK (0 ohms).

Issue:  the compressor relay (on the control PC Board) is not being energized - no 12Vdc across the relay coil.  All other functions appear to function correctly - Fan speed, temp, etc are all functioning. 

Anything specifically known to fail on these boards?  The board appears to be RepairClinic P/N 944300, but would like to avoid replacing the entire PCB.

 Anyone have a old used PWB from a scrap unit?

Thanks!

do you have a GE part number for that PC board ?

Thanks for the  quick response.   I don't have a Service  Manual, so I can only provide the number from the paper tag on the board:  DB93-00874B.

By the way, one assumes I can simply jumper the AC portion of the relay to force the compressor to kick on, correct?  I just wanted to ensure it was worth repairing.

It may just be a bad Relay

looks like it's a Samsung part number

I don't even know if window units have "low pressure switches", but if it is low on refrigerant, an open pressure switch would prevent the compressor from coming on.

You could test this by bypassing the compressor relay on the board . Connect L1 (verify on unit diagram) to the relay output.(while unpowered of course)

If, when you plug it in it blows cold for more than a minute , you may have a bad board( or if it has pressure switches, those need to be checked for open circuits). If it does not blow cold and the compressor is running, you have low refrigerant.
