Why would my heater suddenly stop working?
There could be an issue with the thermocouple (it may be loose or faulty), the orifice could be clogged or jammed or the flame may be set too low. If none of those seem to be the problem, there could be a problem with the safety valve.

Thermostat not turning on heat Make sure the switch is on “Heat” rather than on “Cool.” Check the temperature setting. Compare the temperature setting to the room temperature. Set the temperature five degrees higher than the room temperature and see if the furnace kicks on.
How do I reset my heater?
How to Reset an Electric Furnace
- First, turn off the power supply to the furnace by turning off the breaker in the circuit box.
- Locate the reset button on the furnace and press it to reset the furnace.
- If the button is popped up, press it down.
- Return the cover to the blower compartment and turn the power on.
Why is my gas heater not working?
The reason why your furnace is not working is probably that the power supply has blown up. Another reason can be the tripped or blown circuit breaker. Check the breaker panel to see if the circuit breaker has tripped or blown. If that is the case then you should call reputable gas heater service to fix the problem.
Why is my furnace blowing cold air when the heat is on?
Your furnace may be blowing cold air because the filter is too dirty. A dirty air filter blocks airflow over the furnace’s heat exchanger, causing it to overheat. When overheating, your furnace can trip a high limit switch, causing the furnace burners to shut off so that the heat exchanger does not crack.
Why will my central heat not come on?
Check the thermostat for power and proper settings. Turn on the thermostat and set the temperature so the heater comes on. If it does not come on, locate the circuit breaker for the central heating unit and verify that the breaker is functional. Turn it off and on again, in case it has tripped.
Why is my central heat not turning on?
Check the Thermostat When your furnace won’t ignite, the first thing you should do is check your thermostat. Turn it on and set the temp to the degree that will make the heater turn on. If it doesn’t come on, check your circuit breaker to see if the breaker for your central heating unit has been tripped.
The Reset button is usually located on the back of your device but can be found on the bottom in some cases.
Why did my heater stop blowing hot air?
First, check to make sure the thermostat is set correctly. You will want to make sure that the fan control is set to auto, and not ‘on’. If the thermostat appears set correctly, turn off your heater at the thermostat and check the filter. If the filter is dirty, replace it.
