You rely on your furnace to provide heating when you need it, no matter time of year. Spring is often a great time to make any necessary repairs or replacements to your heating system, without the risk of extensive downtime during the cold months. One of the most common problems with the home furnace is that its blower motor does not run properly. While a professional diagnosis is best left to your local heating technician, there are some signs that your furnace blower motor is defective.

Your furnace blower motor is controlled by a thermostat. When the hot air in the furnace reaches a certain temperature, the motor should turn on and blow hot air through the air handler. A defective blower motor halts this process, and your furnace can’t work without it. Here are some common problems:
- Blower doesn’t turn on. This is hazardous because you don’t want heat to buildup in your furnace firebox with nowhere to go. This is probably an electrical issue.
- Blower doesn’t shut off. While this is better than its opposite, your blower should not blow hot air before the system reaches a certain temperature. This could also be a problem with your thermostat.
- Faulty fan limit switch. This device controls when the furnace blower turns on and off, in order to prevent the furnace from blowing cold air into the home. But it’s also a safety control that protects the furnace heat exchanger from damage if the temperature inside the furnace gets too high. As an auxiliary component of the blower motor, it may require repair or replacement as necessary.
- Blower is too noisy. This could be a dry bearing or a loose belt that connects the blower motor to the fan. Depending on the extent of the damage, it may indicate either repair or replacement.
Keeping an eye on your furnace blower motor is an important step to maintaining the integrity and safety of your system. For comprehensive furnace blower motor repair or replacement in Brick, NJ, call Heritage Air & Heat today!
