Rob for Model Number lre30453sw If you open the oven door while it is heating up, the display will read power failure and the convection heat icon flashes. The door switch seems to be ok, but the oven light doesn't work.. I replaced the transformer as well as the oven sub control . The main board was replaced as part of the recall. When the tech replaced the board I mistakenly left the oven light bulb out, when I replaced the bulb the display went back to power failure.
Answer Rob, Based on the information provided, this issue sounds like it would be caused by a fault in the main control board. It sounds like the relay for the oven light may be shorting out. You will also want to check to make sure that there are no loose or damaged wires that could be touching ground. Read More... Answered by AppliancePartsPros.com | Monday, April 21, 2014
