Went to pull out the Perfectoe heater, removed grate and two screws holding unit in cabinet, will not come out of the slot. Removed big bottom drawer and gazed in to find that the fine folks in Colburg had made the romax to short to be able to remove the heater without cutting the wire. Went in to check the breaker to make sure it was off, flipped it on and hey no heater noise, not running, went and cycled the knob and it works like new. Problem solved must be the heater gremlin.
