MEDB850YW Maytag Bravos XL dryer stopped heating three days ago. Running diagnostics showed an F4E4 code, and install diagnostics was L2. I confirmed the circuit breaker was 240, and the outlet was 240. I ran without any vent hooked up and still no heat. I then followed the service technician instructions for CCU power tests and everything was correct. (Attached the tech sheet so you can see what I was following).

I posted this to that old thread, but then realized it would be best to start a new thread.
It is my understanding that this means the relay is toast (right? since I know each has 120V but not 240 between them?), and I'll need to replace the board?
Big thanks to everyone.
