The blower motor in your furnace blows hot air through the ducts and into your home. Its capacitor works like a battery and stores the energy needed by the blower to work properly. But with a bad capacitor, your blower cannot function well and may put your family’s comfort at risk.
A bad or faulty capacitor can exhibit many signs and symptoms. Read on to know some of them:
Humming Sounds
The humming sounds created by the blower are indications that the capacitor has electrical problems. There’s no other way for you to capture the issue, but to listen closely to your blower. To do this, turn up your thermostat and wait for the heating system’s blower to start up. Using a screwdriver, open your furnace’ access panel and then lean close to your blower’s housing to hear the strange noise inside. If you hear a humming sound, schedule a professional inspection immediately.
No Power
A bad capacitor prevents the blower from functioning completely. If your unit stops working and you suspect the issue roots from your capacitor, check it right away. Before checking, make sure the fuse that controls the heating system is switched ON. Once the furnace receives power, turn up your thermostat and observe if your blower starts to work within the next few minutes. If you see no response coming from it, your capacitor is definitely failing. For complete inspection and diagnosis of your capacitor, call the experts.
Erratic Motor Operation
Since your capacitor acts like a battery and holds the charge necessary for the blower motor to run properly, it should always stay in peak condition at all times. But with a bad capacitor, your blower motor might run slowly, get extremely hot, and work strangely. Now, if you notice your heating system’s motor frequently short cycles or acts weird, call the experts to test the capacitor.
