I have an electric convection oven, Amana, about 6-7yrs old. The broil element and broil functions work fine, as does the cooktop.

Bake function does not work, you can set temp for bake, hear a click or two, but not heat on the element. The element has continuity. After turning the oven to bake, I read 0 volts across the element terminals. I get 120V from each terminal to ground though. Any thoughts? Thank you.

What did you read across both wires (at least one has to be disconnected from the bake element)?

After pulling one of the leads off, one side is 0V to neutral the other is 120V. The 0V side can be traced back to a board in the lower RH side of the back of the oven, roughly 10" off the floor. Its contact on the board has 0V. I assume this is some form of relay board. The schematic is labeled Bake E11 is the where the wire contacts the board. Would this mean the board is bad?

Yes, the relay board is bad and it has to be replaced.

- The part number for the relay circuit board is AP3970410

I tore into the oven again, and removed the board to inspect the solder on the relays, and all appeared good. I put the board back onto the mounts and decided to tap on the bake relay with the back of the screwdriver thinking it was hanging up. I tested the voltage again and 120V, and the element started to bake. We've used the oven a couple of times without any problems.

Did I get lucky, will this most likely happen again, and more importantly is there any safety concerns here? Thanks again for all you help

From my experience, it will happen again and, most likely, when you will need it the most.

As far as safety goes, there is a possibility that the bake relay will get stuck in the closed position causing your oven to get out of control.

I would recommend to replace the relay board as soon as possible.
