Most of what goes wrong with the MER4320AA sits behind the rear oven panel, which is why a diagnosis here is worth more than a guess. Where a part has been revised, the plate is the only reliable way to tell which version the machine takes.
This one is isolate first, inspect second: power off at the breaker, then noting when the fault appears and keeping the door seal clean, then a technician for anything further.
