Can get the thermostat HEAT function to work. Just replaced…

Customer Question
Can get the thermostat...

Can get the thermostat HEAT function to work. Just replaced an old analog Honeywell with a new digital HW. Four wires were connected: W, R, G & Y.

Contractor's Assistant: Did you double-check the thermostat's settings? And what about the filters?

Pulled the filters - they look dirtier than a Mustang Ranch worker. Think I need to replace them, As to T settings, what specifically?

Contractor's Assistant: Do you plan on doing the work yourself?

Yes. Im a VN vet on a limited income....

Contractor's Assistant: Anything else we should know to help you best?

Well, the FAN function works, but it just blows cold air. The programmed heater function has worked a couple times. Unpredictable. When we turn up the temp on the T, we get no response, however. Can hear the blower motor humming - just nothing kicking in...

Russ here. Also VN vet Air Force. Go into installer setup on the thermostat and disable the programable and go to non programmable. Try furnace to see if it works. Also make sure you have the correct setting for furnace. Russ
