Customer Questions and Answers for Oven Control Board by Whirlpool

Brian, it would be recommended that the wires are checked for any loose connections or bare spots. If the wires check good, then the next step would be to verify that a full 240VAC is reaching the terminal block by testing from the red wire with a meter probe to the black wire with the other meter probe. If there is 240VAC, the next step would be to identify if the cooling fan WP74004947 is receiving 120VAC to allow it to operate and keep the main control at an operational temperature. If it is receiving 120VAC but is not rotating, it has failed and would need to be replaced. If it is rotating then it is likely that the main relay control W10757086 is failing.
