Furnace blower motor capacitor polarity.

Its capacitor works like a battery and stores the energy needed by the blower to work properly. Like a battery the capacitor stores the extra energy that is needed to jump start the furnace blower. Have two capacitors called a start and run capacitor. Problem indicators what you can do.

How to check a run capacitor. Where is a furnace capacitor located. This is the most common design type. If not the capacitor or the blower motor is not functioning properly.

If the furnace is receiving power turn up the thermostat and see whether the blower motor starts within the next few minutes. Follow these instructions to install a furnace blower motor capacitor. The blower motor in your furnace blows hot air through the ducts and into your home. Without the capacitor the blower would not start because the run capacitor initiates the blower fan to start turning.

To answer this question the panel door to the furnace will need to be removed. Have only a single capacitor. The start capacitor gives a fan motor the torque it needs to start spinning then stops. It will switch back into circuit once the furnace blower motor drops below the predetermined speed.

Not have a capacitor at all. Your furnace uses a lot of energy so to supply the extra energy needed to power the blower gas furnaces have a capacitor. A start or run capacitor can be combined into one capacitor called a dual capacitor with three leads but can be split between two separate capacitors. 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. Diagnosing a problem with a blower s capacitor requires an understanding of the capacitor s function. Before checking the capacitor make sure the fuse controlling the furnace is flipped to the on position. Some units do not use a capacitors to run the blower motor.

While the run capacitor stays on giving the motor extra torque when needed.
