The blower in your furnace is an essential part because, without it, hot air can't circulate through your home. The parts that control the blower are the blower wheel, capacitor, and motor. If any of these parts malfunction, your home may not get or stay warm. These are signs of a blower problem in your furnace and the furnace repairs that could be needed.
Signs Your Furnace's Blower Is Bad
One important sign to watch for is a burning odor. This can happen when the motor overheats trying to spin the blower. Some furnaces will shut down for protection when the motor overheats, but some furnaces may not. This could pose a danger if the motor overheats and doesn't burn out. It could become a fire risk.
A burning odor is always a sign to take seriously. Call a furnace repair company right away and let them know so you can get help quickly. Other signs include loud noises as the blower system struggles to work with malfunctioning parts. Also, if the blower isn't working, no air will be coming out of the ducts, so your house will get cold.
Repairs That Might Be Needed
Your furnace repair technician has to troubleshoot the problem when your blower system malfunctions. They may use a multimeter to test the capacitor, control board, and motor. They'll also inspect the area to look for a buildup of dust and grime that could cause the problem.
Depending on what they find, your furnace may need to be cleaned, especially the burner wheel. The wheel may need to be removed and scrubbed to get it clean. Then when it's replaced, the repair technician will tighten it well to prevent vibrations and other loud noises.
If the capacitor is bad, it will need to be removed since capacitors aren't generally repaired. Instead, a new one will be installed. A bad motor will probably need to be replaced too, although the technician may try to see what's wrong with it to see if it can be repaired.
It's possible the problem could be with the thermostat or control board that both work together to trigger the blower to come on. If so, the thermostat may need to be cleaned, repaired, or replaced.
The wiring from the thermostat to the control board may need to be tightened or replaced. If the issue is with the control board, the control board may need to be taken out and replaced with a new one so the blower is triggered to turn on when your furnace starts making heat.
