Why is my heater not coming on?
If your furnace does not heat at all. Thermostat malfunctions cause most heating system failures. Other causes include a tripped circuit breaker or blown fuse, or—in the case of combustion furnaces—a pilot light that has gone out.

What’s the difference between communicating and non-communicating HVAC?
Non-communicating HVAC: The thermostat is the switch – If there’s a call for heat, for example, the thermostat closes contacts to complete a circuit and deliver voltage to the relay, which closes other contacts to extend the voltage to the furnace or heat pump When the thermostat set point is reached, the thermostat opens the contacts,…
How many wires are in a non communicating thermostat?
One minor difficulty is that that non-communicating thermostats contain up to 12 wires for the many functions possible—furnace, AC, second-stage furnace, second-stage AC, heat pump, heat pump reversing valve, blower motor, fan only mode, auxiliary heaters in heat pumps plus the c-wire, or common wire.
What does it mean when your heating system is not working?
NO AIR – Continue to the Furnace or Heating System section. ROOM TEMPERATURE – Continue to the Thermostat Functionality section. WEAK HEAT (WARM) – Continue to the Fan section.
Can a HVAC system be rewired to be non communicating?
It depends on the brand and piece of equipment. If it is possible, the communicating components and the thermostat will have to be rewired to be non-communicating. You will lose any communicating capabilities. Check with your HVAC pro to determine if your communicating system can be modified and if you’ll need a different thermostat.
