9 Best Ways on How to Fix a Broken Heater

1. Check the Thermostat:

One of the first things to check when your heater stops working is the thermostat. Make sure that it is set to the correct temperature and mode (heating or cooling). If it seems like there are issues with the thermostat, you can try replacing the batteries or cleaning any built-up dirt or debris from the inside. This is a simple fix that could save you from having to call a professional.

2. Replace or Clean the Air Filter:

A dirty air filter can cause your heater to malfunction, so if it has been a while since you last checked or replaced it, now would be a good time to do so. A clogged filter can restrict airflow and put extra strain on your heating system, making it less effective. Make sure to clean or replace your air filter at least once every three months.

3. Check the Circuit Breaker:

If your heater is not turning on at all, check the circuit breaker to see if it has tripped. If that is the case, simply reset it and try turning on your heater again. If this continues to happen, it may be a sign of a larger electrical issue and you should call an electrician. Checking the circuit breaker is an easy and quick step that could potentially save you from having to pay for professional help.

4. Inspect the Pilot Light:

Older gas heaters may have a pilot light that needs to be manually lit. If your heater is not turning on, make sure to check if the pilot light is still lit or if it needs to be reignited. If the pilot light keeps going out, there may be an issue with the gas supply or thermocouple and you should contact a professional for help.

5. Check Gas Supply:

If your heater is fueled by gas, make sure that the gas supply is turned on and that there are no issues with the gas line. Sometimes, issues with the gas supply can cause your heater to malfunction, so it is important to rule this out as a potential issue. Checking the gas supply is a simple step that could save you time and money in the long run.

6. Clean the Burners:

If your heater has been running for a while, the burners may become dirty or clogged with debris, affecting their efficiency. You can easily clean the burners by following the manufacturer’s instructions or using a soft brush to remove any buildup. Regularly cleaning the burners can help your heater run more effectively and prevent future malfunctions.

7. Check for Leaks:

If you have a furnace or gas-powered heater, it is important to check for any leaks in the system. You can do this by using a mixture of soapy water and checking for bubbles around connections and joints. If you find a leak, it is important to contact a professional immediately, as gas leaks can be dangerous and should not be handled by amateurs.

8. Call a Professional:

If you have tried all of these steps and your heater is still not working, it may be time to call in a professional. They will have the expertise and tools necessary to properly diagnose and fix any issues with your heater. While this may cost more than attempting DIY fixes, it can save you from potential safety hazards or cause further damage to your heating system.

9. Consider Replacement:

If your heater is older or has been experiencing frequent malfunctions, it may be time to consider replacing it altogether. A new heater will not only provide more reliability and efficiency, but it can also save you money in the long run on maintenance and repair costs. Consult with a professional to determine if repairing or replacing your heater is the best option for you.

Regularly Maintain Your Heater

Following these tips can help you diagnose and potentially fix a broken heater. However, if at any point you feel uncomfortable or unsure about fixing your heater yourself, it is always best to call a professional for assistance. Remember to regularly maintain your heater to prevent future breakdowns and always prioritize safety when dealing with heating systems. Stay warm and cozy this winter!
