Randomly beeps “error L43 relay” when not being run. Checked both upper oven power relay and lower oven relay but no visible damage and the error doesn’t always come up only every couple hours a breaker reset fixes it temporarily. Would this be the lower oven relay? I need the diagnostic manual BUT MORE IMPORTANTLY an answer to which board it is?
