GE window a/c: compressor wont shut off.

When plugged in and the power button pushed the compressor comes on and wont shut off, even in fan mode. If I press the power button to turn off all the digital lights go out on the control board but "Only" the compressor is running.

I removed the control board thinking it might be the problem and when it was removed I plugged the a/c in and the unitl came on and a few seconds later the compressor came on. I could sure use some help.

Thanks in advance.

This is a GE 10,000 btu unit with control board 30562011 D2115A

Welcome to the forums.

That is the display/control board. There is another board or some type of relay that controls the blower and the compressor. That's where the problem is. Most likely a stuck relay.

Without a model number I can't help much further.

In looking at that PS/switching board..... it looks like fairly old technology which means this must be a fairly old window A/C.

I've highlighted the relays. The two with the red arrows, I believe, are the fan relays and the one with the yellow arrow is the A/C compressor.

In re-reading your first post I'm not so sure it's a stuck relay as if it were.... the compressor would start as soon as the unit is plugged in. That leaves us with a logic problem that will be difficult to diagnose without test equipment.
