What are the five reasons why the furnace isn't heating up?

1. The pilot light is out. It is the most common reason why a furnace will stop working. First, check to see if the pilot light is still lit. If not, relight it according to your owner's manual instructions. In case you need furnace repair in Palo Alto, visit the website.

2. The furnace needs to receive power. Check to ensure the furnace is plugged in, and the circuit breaker has not tripped.


3. The thermostat is set to "off" or "cool" instead of "heat." However, the temperature setting is high enough to trigger the furnace to come on.


4. The furnace door is open. Ensure the door is closed so air can circulate properly through the unit.


5. The air filter is dirty. A dirty air filter will restrict airflow and cause the furnace to overheat, shutting down as a safety measure. Change the air filter according to the manufacturer's instructions.
