If you get to the wires to the thermostat and put the RED (RH) wire to the WHITE (W) wire does the heat turn on?

Then you have an issue with the furnace you would have to check the furnace for any error codes

Yeah, I figured it was a peoblem with the furnace but this is an old furnace and has no error codes.
HVAC Technician: HVAC Guru, HVAC TECH replied 4 months ago

It would depend on the make and model of the furnace and the wiring diagram to see what the issue is.

Thanks for your time. I will get it figured out. Just thought I would try this system to see how it worked and now I know. By the way, how do you get your answers? Google it.
HVAC Technician: HVAC Guru, HVAC TECH replied 4 months ago

No I work on furnaces and AC units for a living so without a make, model of the unit I can not tell you a whole lot, so I am not sure about the google it comment as I was able to rule out the thermostat as the issue, but the I have no idea what system you have as nothing else was indicated.
