I have a Harman Accentra FS model, just over a year old. A couple of days ago, the stove was throwing a 4 blink code. Though & behold, the cat pulled the room sensor cord down & chewed the end of the cord. So we ran it on stove temp rather than room temp. Bought a new room sensor cord yesterday. Cleaned the stove today, installed the new cord & it would not start in room temp mode. Started fine in stove temp & is running fine. We also double checked to make sure the cord was installed correct. Is there something we are doing wrong? Do we need to reset something to get the room sensor cord to work?
