Whirlpool Microwave. Stopped heating.

Have checked door switches, all good.

Performed "touch panel and electronic control test" per tech sheet. When placed into diag mode, display reads 5.5B 5.

When "cook" key pressed, display reads "sensing" then displays 463, then 464.

When "4" key is pressed, display reads "076".

I have not been able to find the secret decoder ring to determine what those responses mean. I suspect controller is compromised, but need independent confirmation.

Cheers,
PT

Does it run but not heat? If yes, replace the magnetron and diode.
