The compressor is a FC75Lane.

I have not plugged the unit in for a while since the day I hot wired the compressor to 110v, ran it for a min or so, then put it all back and it was still just clicking repeatedly and flashing the led on the board.

Today after reading the manual tgoods was so kind to provide I plugged it in and no clicking at all but compressor will not run, so I put unit into test mode by pressing the button on the main board once, which is supposed to run all fans and the compressor.
Everything runs except the compressor, PWB board does not click at all and no led activity.
The part is showing out of stock on both sites repairclinic and appliancepartspros and a few other sites I tried so I assume this is a common failure item and maybe just a coincidence and the flood water has nothing to do with it?
It did run fine when I first cleaned the board with wd-40 after the hurricane.
Anyone else replace that board before for same symptoms?
P/N is ABQ73004302

Update:

I ordered the compressor control board assembly from RepairClinic.com and they showed a new part number that superscedes the original P/N ABQ73004302 the new one is ABQ73004304

I guess they made some updates to this board hence the new part number.

It fired right up and compressor runs fine now.

I was afraid I may have damaged the compressor by hot wiring the pins to 110v directly to test it but seems to be working and it has been 4 days running so far.

Thanks for all the advice and the service manual!

     No damage at all that is how the factory wants us to test. 10 warranty on them hardy compressors.. Voltage from 20v - 200V. will harm this compressor.. if you move it or lay it down. and start the compressor and it makes a load noise. you may have too hit the fount of the compressor as the magnet my stick too the side.


Cool Refrigerator for the price of a control board.

Check the Basics first!!! Read the Manual !!!Buy the tech a Beer!!!
