-
Check the power supply: Make sure the furnace is plugged in and the breaker hasn’t tripped.
-
Inspect the thermostat: Ensure it’s set to heat mode and at the correct temperature.
-
Look at safety switches: Many furnaces have a limit switch or door safety switch that prevents operation if a panel isn’t properly closed.

-
Check the gas supply: Make sure the valve is open and there’s no obstruction.

Noisy furnaces can be alarming but often indicate minor issues:
-

Clicking sounds: Usually normal during startup or shutdown, but persistent clicking could indicate ignition problems.

Blower motor issues: Check the 9-speed ECM motor for proper operation.
Maintaining your furnace regularly helps prevent airflow problems from developing.

If your furnace cycles on and off frequently:
-
Overheating: Limit switches may shut down the furnace to prevent damage.

Thermostat misreading: Ensure it’s not near a heat source or in direct sunlight.
