A furnace motor is an electric motor that powers the blower in a furnace. The blower circulates air through the furnace and the home. The furnace motor is usually a single-phase motor, although some furnaces use a three-phase motor. The motor is connected to the furnace by a motor mount, a metal bracket that holds the motor in place. The motor mount also has a hole in the middle that the blower shaft passes through. Finally, the blower shaft is connected to the blower fan, blowing air through the furnace.
Like any machine, a blower motor is vulnerable to breakdowns, wear, and tear. As a homeowner, you should be able to spot the signs of a poorly performing furnace blower. Maintaining your furnace blower motor can save you time and extend the lifespan of your HVAC system. Here’s what you should know.
If you hear a loud noise when your furnace is running, there’s a good chance it’s the motor. This is a common issue with furnaces that you can fix relatively quickly. However, you can do a few things to resolve the problem yourself before calling a professional. First, check if the furnace motor is covered in dust or dirt. You can try cleaning it off with a brush or a vacuum if it is. Be sure to do this when the furnace is turned off, so you don’t get burned. Otherwise, you may need to contact a furnace repair service or professional HVAC technician.
If your furnace fan is not spinning, it may be time to replace the motor blower. Sometimes, your fan won’t spin at all. Other times, the fan is making a lot of noise or not blowing as strongly as it used to. There are a few reasons why your furnace fan might not be spinning. One possibility is that the fan motor has failed. This can be caused by several factors, including age, wear, and tear, or damage. If the fan motor has failed, you will need to replace it to get the fan spinning again.
Another possibility is that the fan blade has become damaged or warped. If this is the case, the fan will need to be replaced to get it spinning again. Finally, there could be a problem with the HVAC system‘s fan switch or wiring. If this is the case, you will need to investigate and fix the issue to get the fan spinning once again.
If your furnace motor isn’t turning on, it could signify that you need a new motor blower. In some cases, the blower motor for furnace models isn’t turning on, or the furnace motor is turning on, but it’s not blowing air. Maybe, the furnace motor is blowing air, but it’s not blowing enough air.
A furnace with a faulty motor blower may not be working correctly, leading to several safety hazards. If your furnace does need a new motor blower, the technician will likely recommend that you replace the entire furnace. This may seem like a daunting task, but it is essential to remember that a new furnace will save you money in the long run by helping you conserve energy and reducing your energy bills.
When choosing a new furnace, it is essential to consider the size of your home, the type of fuel you use, and the climate in your area. A furnace technician can help you choose the right furnace for your home. If you are unsure whether or not your furnace needs a new motor blower, it is best to call a furnace repair technician for a diagnosis.
