:eek: The thermostat is set for 70 degrees. The room temperature is 63 degrees.
I went outside to check the furnace and it is running. The fan is not running and there is no heat. I replaced the thermostat and I get the same results.

FranMac,

What are you seeing outside that makes you think the furnace is running other then the blower? Do you feel heat coming from the exhaust outside or just air?
