Hi happycamper,
Welcome to the forum.
You should contact Bradley right away, since your warranty is about to expire.
Your problem is extremely unusual. If the bisquette burners do not work, that should shut your P10 down. There are bisquette heat sensors, and if they don't detect a certain amount of heat within in a certain amount of time, it will disable your heating elements. At least that is what happen to mine, but Bradley may have change that function in later firmware upgrades.
if the bisquettes are sitting on the burners for approximately 20 minutes and do not smolder, then the issue is your bisquette burners. If the bisquettes are just cycling through without resting on the burners, then there is a problem with the turntable. Either problem it is best to contact Bradley.
