Good Morning, I have been having a situation in my own house that is driving me crazy. A few days ago (in the morning) my furnace did not kick on when the programmable themostat called for heat. When you turned the thermostat off and on the furnace then turned on.
The next day it did it and I changed the batteries.
The next day it did it so I changed the thermostat.
It did it again this morning…(new thermostat, new batteries)
It only happens when it goes from the night time setting to the morning setting. When it is running in the afternoon and evening (when I am home) it kicks on every time it calls for heat.
Any thoughts? Am I missing something small or big?
