Woke up yesterday and the heat wasn't working. I hit the reset button and it restarted, but when I got home from work last night, it was off again. Called the service guys and had to wait 2 hours for a repairman. No problem. I made dinner.
Turns out there's a little switch that needs to be engaged for the heater to work. When engaged my heater does NOT work, but when it is NOT engaged, it works fine. Go figure. So we gerry-rigged something that will keep my house warm, and a replacement part has been ordered.
