PC Control Board - FRONT - US061

circuit board fixed my classic heater. heater has not worked right since i purchased it 3 or 4 years ago

I ordered this to repair a out of balance problem that is intermittent. This didn't fix my problem. Can you help me with this problem. I know the sensor is on this board. When it works I can move the board right and left forward and backwards and it will go in and out of balance. I know you don't accept returns but could you give me some direction. There are posts all over the internet and no one knows how to fix this problem. I have spent over $50 and it still doesn't work.
