Problem with my Bryant furnace.
I come home or wake up to a cold house. The furnace has stopped working.
First thing I do is beat on the thermostat. Does not work. Turning the
blower to the on position starts the blower motor.
I go downstairs, and reset the furnace circuit breaker. Furnace fires up.
The rest of the day, the thing works fine. Then a day later, happens
I put tape over the door switch, so I can see if the diagnostic LED is
blinking a code next time it happens. I assume the door switch kills
power, thus clearing any errors.
Right now it glows steady. I suppose I need a list of error codes, and
possibly a way to retrive any stored codes, if the board has that capacity.
