I have a LG model LFC21776ST / 00
It was in a few inches of water in Sandy, my neighbor threw it out it was less than a year old so I grabbed it.
The PC Board in lower back by the compressor inside a plastic case, I believe it is a power supply board, was half submerged. I removed the board and sprayed it with wd-40 and brushed it good with a old paint brush then blew it off with air hose. It ran fine for a week then it stopped and the board just clicks every few seconds and led blinks on the board.
I jumpered power directly to the compressor pins and it starts up fine.
The board is around $100 bucks with shipping so I was wondering if it can be troubleshooted and repaired since it does not have many components on it and the chips should not have been damaged from water only the relays may have water inside but they appear to be sealed very well with epoxy around the pins. I tried to jumper the relay pins but no luck same clicking.
The board part number is EBR64173903
Anyone know how I can test it to be sure it is that board because I dont think I can return it if it is not the problem.
The rest of the fridge works and the condenser fan kicks on and all digital temp controls work etc just the compressor wont kick on.
Thanks for any advice.
