Modern furnaces have circuit boards and are "smart" and it is possible the circuit board has gone out.
Is it a gas furnace?
I will give you my 30 year old analog heater experience.
If it is a gas furnace, and presuming the installer followed standard common sense thermostat wiring.
If you can get the top off the thermostat (may be two screws or may just snap off) you will see the wall plate and the terminals. Red should be common (24 VAC) and white should be heat. Short those two terminals and the heater should come on.
This does not apply if you have a heat pump.
