I have replaced the board controlling clock, but lower oven wouldn't heat. Check hear sensor and it's ok. Have the replacement lower relay board in hand, but instructions that came with board say to disconnect and remove the board I just installed, then remove all cables/connectors, then lower relay board. Can I not just unscrew the lower relay board, disconnect/reconnect to new board all wires, then replace new board?
