WR55X10942 is the correct board. It replaces all of the boards that do not have a variable speed compressor. The new boards have a time delay built into them. It can take up to 10 minutes for the board to energize the compressor and fan motors. They keep playing around with the delay times. The delay is there to let the pressure to equalize in the compressor, should there be a short power failure during normal operation. The fans may be on a separate delay to prevent blowing hot air around after defrost. Put it back in, power it back up, and wait.
