For a while now we've noticed temperature differences in our lower oven. Now, it won't heat at all. I took the back panel off and tested the voltage output directly from the control panel. When I turn the lower oven on, I hear the relays "click" and I get a full 220V. Within 1-2 seconds, the relay "clicks" again and the voltage goes to zero. Is this just a bad relay(s) or the whole control panel? If it is a relay, how do I determine which relay is bad?
ANSWER Hello Robert,
The characteristic of the relay clicking on and off is normal operation. This will occur with a new board in place. The test you performed proved you have a good board. Now you should test the lower bake element 7406P428-60 and the high limit 74009969.
