When your furnace stops working it’s easy to forget you can do some troubleshooting before calling for furnace repair. Even if you’re not an HVAC professional, there are 3 steps you can take before calling for professional backup:
Troubleshooting Step #1: Check the Filter
This seems so simple, but the number one reason for furnace malfunction is a dirty air filter. When the filter is full of dust and dirt it prevents proper airflow to and from the furnace unit. When the air isn’t flowing properly, the heating system can overheat and shut down. Check the filter to see if it needs changing. Once it’s changed, wait 30-60 minutes for the furnace to cool down before resetting it.
Troubleshooting Step #2: Check the Thermostat
Again, another simple check, but it’s really common for thermostats to be set incorrectly or changed, which can keep your heat from working properly or heating your home effectively. Make sure the fan is set to on or auto. If it gets switched off, your heat won’t turn on no matter how cold it gets in your home. Check to be sure the desired temperature is also set properly.
Troubleshooting Step #3: Check the Circuit Breaker or the Pilot Light
If you’re still out of luck with the heat in your house, check the breaker panel and look for the switch that controls your furnace. Is it in the on position? If not, there’s your problem. Turn it on. If the problem persists, check the pilot light. If it’s out and you don’t have an electronic start, relight it if you feel comfortable doing so.
If you’ve tried the steps above and you still have no heat, it could mean it’s time for repair service. When troubleshooting doesn’t fix the problem, contact the experts at Universal Heating and Cooling anytime, day or night.
