What to Do If Your Heat Suddenly Stops Working

Posted: March 8, 2016

Heating system stops working

If your heating system suddenly stops working, sometimes there’s a simple fix you can do yourself that will get your heat going and save you the expense of a service visit. Visit our troubleshooting question-and-answer guide for help, or follow these steps:

If you have an oil-fired system:

  • Check the fuel level in your tank.
  • Be sure all emergency valves or switches are in their “on” or “start” positions.
  • Check fuses or circuit breakers.
  • Make sure your thermostat is set 5 degrees above room temperature and to HEAT.
  • Press the reset button on the burner for 3 seconds ONCE ONLY.

If you have a gas-fired system:

  • If you use propane, check the fuel level in your tank.
  • Once again, check your fuse or circuit breaker.
  • Make sure the thermostat is on the correct setting and calling for heat.
  • Be sure all emergency valves or switches are in their “on” or “start” positions.
  • An air filter clogged with debris will cause the system to overheat and shut down. Follow these steps:
    1. Shut off the system’s power. It’s important to do this before you proceed.
    2. Find the air filter. A filter is usually somewhere along the system’s return air duct. It may be in a wall or ceiling, or in the furnace.
    3. Remove the air filter. Many of the new filters slide in and out so it is easy to remove them and put them back.
