Maytag wall oven uses control board 7601P177-60. The only replacement available is 7601P156-60. I bought one, but it doesn't fit. The connector for the temperature sensor has 3 wires, but the old one has 4. Theconnector for the relay board has a completely different type of connector, and the new control board is not made for the relay board to mount onto its back as the old one is. Can all this be adapted? Or am I forced to just scrap the oven and buy a new one? Has anybody out there ever replaced a 7601P177-60 control board before?
