If your furnace won’t start, you may be a little worried about the need to have it fixed. However, you may be able to resolve the issue without help. Before you call your contractor, take time to check a few common factors that can contribute to problems with furnace startup.
Common Furnace Problems
There are several troubleshooting steps to explore as you attempt to get your furnace running again. One of the most common issues is a lack of airflow, often rectified by checking and changing your air filter. You should start the heating season with a fresh air filter, and you should check it monthly to assess whether a new filter is required.
Additional issues to check include the following:
- Thermostat – are your settings correct? Heat should be selected, and the heating setting must exceed the room temperature for a call for heat to be made from the thermostat to the furnace. If settings are correct, verify that the battery is good.
- Fuel – is your pilot lit? If not, you may have an issue with the fuel supply to your furnace, preventing it from starting. Try lighting the pilot. If this doesn’t work, verify that valves are open and that other gas appliances are working. You may need to contact your utility company if an outage exists.
- Electricity – are switches on and plugs intact? Although your furnace uses fossil fuels for heating, it requires a source of electricity for electronic components like sensors and control panels.
If you still haven’t obtained a successful start, you can try a system reboot. Electronic components and control panels can initiate system lockouts at times. To reboot, you will need to do the following:
- Adjust the temperature setting to a level below the room temperature so that there isn’t a call for heat.
- Disconnect electricity to your furnace by shutting off the switch at the fuse box or by unplugging the cord. Wait for at least three minutes before plugging the unit in again or turning on the switch.
- Return to the thermostat, raising the temperature setting above room temperature to initiate a call for heat.
You can complete this task a couple of times if you aren’t successful at first. You can also check the error display on a newer unit for a code that will indicate the nature of the problem. If you are unsuccessful, however, then it’s time to call a heating contractor for furnace repair.
