The blower on your furnace is the component responsible for pushing the hot air generated in the furnace through the ductwork to your living spaces. The blower unit is comprised of the fan, the fan’s motor and a safety device called a limit switch.
Problems developing with any of these components can result in malfunction of the blower. Blower problems should always be handled by a professional, and the heating experts at JW Heating and Air are here to assist you with all of your heater repair needs in Burbank. Call us today!
Common Blower Problems
Here are some of the more common blower problems our experts see:
Issues with the Fan
The most common problem with the fan itself has to do with the blades. Blades can be broken, loose or bent, and while this may not impair the operation of the fan significantly, a loose or bent blade can cause a great deal of damage to surrounding components.
The fan can’t operate without a properly-working motor. Common problems that develop with the blower motor include electrical issues, motor malfunction and breakdown.
Fan Belt Problems
The fan belt is the connection between the motor and the fan; without a fan belt, the fan can’t rotate. Fan belts can stretch, crack and break. Sometimes they can be adjusted, but other times they need to be replaced. No matter what the issue, however, an expert should always handle the work.
Limit Switch Issues
Every blower assembly includes a limit switch. The limit switch is a device that tells the fan when to turn on and off, and it also acts as a safety device. The limit switch has a temperature sensor so that it turns on only when there is warm air and the air is the correct temperature. When limit switches malfunction, many times the problem will present as a fan that doesn’t turn on.
