Why Is My Furnace Running But Not Heating?
A faulty furnace is a common problem during cold winter months. If your furnace is running but not heating, it could be due to several reasons:
- Clogged filter: A dirty or blocked air filter restricts airflow, preventing warm air from circulating throughout the home.
- Dirty flame sensor: A dirty flame sensor can interrupt the gas supply to the burner, causing the furnace to operate without producing heat.
- Malfunctioning thermostat: A faulty thermostat may not accurately sense the temperature, leading to the furnace running constantly without heating effectively.
- Blocked exhaust vent: Obstructed exhaust vents prevent the release of combustion gases and can cause the furnace to overheat and shut down.
- Damaged blower motor: A broken or malfunctioning blower motor cannot circulate warm air throughout the ductwork, resulting in a lack of heating.
