Why Is My Furnace Fan Not Turning On? | Dino Plumbing & Service Pros – St. George, Utah



A furnace fan is essential for circulating warm air throughout your home, so if it’s not turning on, it can leave you in the cold. Here are some common reasons why this might be happening:

1. Thermostat Issues

Ensure your thermostat is set to "heat" and the fan is on "auto" or "on." A low battery or incorrect settings could be the issue.

2. Tripped Circuit Breaker

Check your electrical panel for a tripped breaker. Reset it if necessary, but if it trips again, call a professional.

3. Blown Furnace Fuse

Your furnace has fuses that can blow due to power surges or age. If a fuse is bad, it needs to be replaced.

4. Faulty Fan Motor

If you hear humming but the fan isn’t running, the motor may be worn out or malfunctioning.

5. Dirty Air Filter

A clogged air filter can restrict airflow, causing the system to overheat and shut off the fan for safety.

If your furnace fan still won’t turn on, don’t wait for colder weather to make things worse. Call Dino Plumbing & Service Pros in St. George for fast and reliable furnace repair!
