If the furnace fires up but then shuts off after a few minutes, it could be that the control board is faulty. If the flame sensor does not detect a flame, as a safety precaution, the control board will shut off power to the gas valve to prevent the furnace from heating. A dirty or faulty pressure switch, which monitors the burner to detect a flame, can also cause the furnace not to produce heat. If the igniter fails, it will also cause the furnace not to produce heat. If you arrive home or arise in the morning to a cold house, it could be that the thermostat is set on a low setting, which can cause the furnace not to put out heat. Sometimes a circuit may have tripped, which can also cause the unit not to start.

In this case it will need to be exchanged for a new one. Sometimes, either the thermostat has been switched off accidentally, or the thermostat has completely gone out. If your furnace just stopped working, it could indicate an issue with the thermostat.
