Furnace Troubleshooting Tips
In an emergency situation, here are some quick furnace troubleshooting tips to help you:
- Check the Thermostat: Ensure it’s set to “heat” and the temperature is higher than the current room temperature. If it’s battery-operated, replace the batteries immediately.
- Inspect the Circuit Breaker: Check the electrical panel for a tripped breaker. If the furnace’s breaker is off, reset it by flipping it to the “on” position.
- Check the Pilot Light: If your furnace has a pilot light, ensure it’s on. If it’s out, follow the manufacturer’s instructions to relight it. If it doesn’t stay lit, the thermocouple may need replacement.
- Verify the Gas Supply: Make sure the gas valve to the furnace is open. If your system runs on propane, ensure there is enough fuel in the tank.
- Ensure Proper Airflow: Check the air filter and vents. A clogged filter or blocked vent can cause overheating. Replace or clean the filter and clear any obstructions from the vents.
- Inspect the Furnace’s Exhaust Vent: Ensure the exhaust vent is clear of snow, ice, or debris. Blocked vents can cause the furnace to shut down.
- Reset the Furnace: Some furnaces have a reset button located near the burner area or on the control panel. Press it to restart the system.
- Turn off the Furnace: If you smell gas or hear unusual noises, immediately turn off the furnace and call a professional.
If these steps don’t resolve the issue, call Proto Home Service immediately for emergency service to avoid further damage or safety risks.
