When the furnace starts up the blower begins pushing air throughout your home. Touch the probes from the voltmeter to the terminals of the capacitor and see if the voltage matches the. A lower fan speed on. In the winter the fan should blow slowly to allow for a higher heat buildup in the combustion chamber before the air circulates through the house.

Many electrical devices use some type of capacitor including a furnace blower. The capacitor will still hold a charge even without power. Example furnace blower motor on amazon a1588 1 2hp 230v air handler motor 1075rpm 3 2amp. Read on to know some of them.

Set a voltmeter to the x1 setting. Read here for how to buy a new furnace blower motor and capacitor. Look for the voltage rating on the side of the capacitor. How to replace a furnace blower motor and capacitor.

The blower fan pushes air over the heat exchange. A furnace usually uses a run capacitor to maintain a relatively constant voltage supply to the blower motor. Remove the wires from the terminal and discharge the capacitor using the instructions included with your furnace. In this episode of repair and replace vance shows how to replace the blower motor capacitor in a furnace.

A control board attached to the blower determines when the blower should start. Turn the power off to the furnace. Its capacitor works like a battery and stores the energy needed by the blower to work properly. When the control board initiates the blower the run capacitor closes the circuit to begin moving the blower fan.

Without the capacitor the blower would not start. A capacitor is a device that stores an electrical charge. The blower motor in your furnace blows hot air through the ducts and into your home. Gas entering your furnace is ignited by the pilot light and burners heat the air.

A bad or faulty capacitor can exhibit many signs and symptoms. Your furnace uses a lot of energy so to supply the extra energy needed to power the blower gas furnaces have a capacitor. The blower then moves the warmed air into and through the ductwork in your house. What is a capacitor.
