1. Heater power switch is off

If your heater isn't working, the first thing to do is check and turn off the heater switch. If it's off, turn it on.

Heating system circuit breakers are often turned off by mistake or accidentally. If you were recently in the attic collecting Christmas decorations, or if one of the technicians worked near your stove, your switch may have been accidentally turned off. If you check and find that the power switch is on, proceed to the next step.

2. Check your heater's circuit breaker

The quickest way to fix a central heating not working problem is to check the circuit breaker first. Make sure the heater breaker has not tripped. If that's the case, the reset should get the heater working again.

Heating systems have built-in safety measures. So if there was an overheating or power surge somewhere in the electrical wiring, the circuit breakers may have tripped. And if the breakers trip again after you reset them, it's a sign that there may be a serious issue that needs to be addressed. In that case, it's appropriate to call a licensed professional HVAC technician to have a look.

3. Check your oven's air filters for dirt

Now that you've checked the power switch and heater breakers and everything looks good, now it's time to check the HVAC air filters. Dirty or clogged air filters cause a number of problems with your heating system. If your heater does not turn on, skip this step.

For safety reasons, remember to turn off the system to check the condition of the air filters. And when you're done, close the door. If the port is not properly closed, your system will not boot.

When the fan motor stops working, there will be no air in your home. You can tell if the fan motor has a problem if its wheels turn slowly and shut off immediately.


8. Dirty flame sensors

Dirty flame sensors are common causes of central heating not working. An oven flame sensor is a straight or L-shaped metal rod located behind the burners.

Flame sensors are designed to detect flames in your oven. If they can't see any flames within about 10 seconds, they close the gas valve to prevent gas from entering your home. A dirty flame sensor can also be yoursOven to start short cycles.

Over the years, dirt and other substances can build up on the sensors, making it difficult to detect flames. See how to clean them.

  • Turn off the oven with the on/off button or thermostat.

  • If there is a lot of debris on the sensor, gently rub it with steel wool or sandpaper.
  • When finished, place the sensor in position before turning on the oven.
