Upper and lower oven will not heat when used in bake mode. Checked for voltage coming from control board and it registers 0. Do I need to replace the oven control board?
If you check at the control board and get a 0 reading then it sounds like you are loosing power to the control board. You will want to trace your wires back to make sure that there are no thermostats that could be faulty and check to make sure that there are no loose or broken wires. If all checks ok then you will want to replace the control board.
i have tested the wiring for lower element on oven and check out element and checked thermostat most likely control board
I see that Whirlpool has replacement board w10166967 for the maytag #7400992 is this a exact match or should i order the overlay also will all the connectors be the same?
Answer John, Yes, the ERC / Clock should be a straight across trade out. Just make sure you label the wires as you remove them from the original ERC. It'll be a lot easier in long run. As for the "overlay, you would probably want to have one handy. Quite often they have a tendency to wrinkle and crease when being removed from the original ERC, Unless you're very careful. It doesn't present a very pretty picture when the job is completed.
