My 2001 Profile 30 keeps shutting down with the control panel blinking as a result of a fault. Stove can be clean or dirty, hot or cold when this happens with no evident pattern or reason. They did do a free replacement on power cords due to a problem and I did replace mine. Not sure what could be wrong. Lots of new parts on it - control panel, auger motor, wiring harness, photo eye, etc. Stove will run fine for days then go through a period where it faults a lot. Any ideas?
