Why Would My Furnace Not Blow Any Air After It Was Just Working?
Several common reasons can cause a furnace to stop blowing air even after it has been working correctly. Here are some potential causes and troubleshooting steps:
- Clogged air filter: A dirty or clogged air filter can restrict airflow, causing the furnace to overheat and shut down. Replace the air filter and check it regularly.
- Faulty blower: The blower motor, responsible for circulating air, may have failed. Check if the blower is running and replace it if necessary.
- Overheating: An overheated furnace can trigger a safety mechanism to shut off the airflow. Inspect for any blockage in the flue pipe or heat exchanger and check if the thermostat is set correctly.
- Electrical issues: A malfunctioning electrical component, such as a capacitor or wiring, can disrupt the furnace's operation. Contact a licensed electrician to inspect the electrical system.
- Malfunctioning thermostat: A faulty thermostat may not send the correct signal to the furnace to turn on the blower. Replace the thermostat to resolve this issue.
