Equipment is 7 year old Bryant 90+ propane furnace and matching AC. We've had the property 2 years - it's where my tractor manuals are stored.
The furnace fails to ignite quite often - it tries 4 times, and then goes to sleep for 4 hours to retry. I'm competent at cleaning the flame sensor, burners, etc. To bypass the 4 hours in really cold weather, I turn the 120v power OFF/ON to get it to restart. We're in a week of single digit temps.
I noticed after the IGNITE FAILURE came on, the heat pump was running - at 10 degrees. What can the heat pump do when it's that cold? How does this furnace try to make heat when the room is below set temp, and the auxiliary heat will not come on?
The thermostat is Bryant's Evolution model (it's smarter than I am!)
