Home Heater Didn’t Turn On? What to Do

One of the most common HVAC questions during the winter months is, “Why won’t my furnace turn on?” Although the failure of your system to function may require heating repair, there are times that don’t require a service call. Nobody wants to spend money on a call that can be avoided, and you can take some initial diagnostic steps to ensure that it’s not a simple problem with an easy fix.

Troubleshooting Your Furnace

When your furnace doesn’t respond right away, it’s important to verify that there isn’t a disruption in the flow of gas or electricity to the system. Evaluate the following:

  • Do your gas appliances work? It’s possible that there is a disruption in the utility service, requiring contact with the provider.
  • Is the manual shut-off valve for your gas supply in the off position? Turn it on.
  • Are fuses and circuit breakers intact? You may need to reset a switch.

You also need to verify that your thermostat is operating correctly. A battery failure can affect the unit’s ability to turn on your furnace, and a fresh battery may resolve the problem. You also need to be sure that the settings are correct for heating. Check that the control is in heat mode and that the temperature setting is higher than the room temperature displayed on the unit.

Continue with your inspection of your equipment, verifying that the air filter isn’t excessively dirty and that there aren’t any obstructions near your vents. You may also need to check the pilot to see if it is still on. You can check your owner’s manual for information related to resetting your system or relighting the pilot. At times, a furnace will cease operation because of overheating. A reset may enable it to work correctly again, but subsequent tripping of the system requires a heating service call.

Limiting Your Susceptibility to Heating Emergencies

Not all system problems are emergencies, and personal troubleshooting can save you a lot of time and money. However, it’s important to get help quickly if these steps don’t resolve the issue, particularly if the weather conditions are very cold. Preventive measures are important for limiting the likelihood of your need for assistance during the winter heating season.
