When the temperature drops, a heater that won’t run can be stressful. So if it suddenly stops working, it may be due to clogged filters, thermostat or fuse issues, a tripped breaker, or an ignition failure.
It’s always best to call an HVAC professional if you’re facing an issue you’re unable to handle yourself. While you’re waiting for them, there are a few common causes you can check.
Acting early can prevent bigger problems and ensure your system stays reliable all winter.
Multnomah Heating, Inc.’s technicians specialize in furnace and heat pump repairs, but we also want you to have the knowledge to do some basic troubleshooting before scheduling a service call.
5 Common Reasons Your Heater Stops Working
Our team sees the same issues again and again during the colder months. Here are the most common causes:
- Dirty or Clogged Filters: A blocked filter restricts airflow, making your system overheat and shut down.
- Thermostat Problems: Incorrect settings, dead batteries, or a faulty thermostat can prevent your heater from turning on.
- Tripped Breakers or Blown Fuses: Electrical issues can cut power to your furnace or heat pump.
- Blocked Vents or Registers: Closed or obstructed vents reduce airflow and can trigger safety shut-offs.
- Ignition or Pilot Light Failures: Gas furnaces rely on ignition systems that can fail over time.

What to Check While Waiting on an HVAC Company
Many heater issues are minor and can be checked while you’re waiting for a professional to come by. Try these quick checks:
- Make sure your thermostat is on “Heat” and set above room temperature.
- Replace or clean your air filter if it’s dirty.
- Check your breaker panel to ensure the furnace or heat pump circuit is on.
- Verify that all supply and return vents are open and unblocked.
- For gas furnaces, confirm the gas valve is on and the pilot light is lit (if applicable).
