Capacitor On Gas Furnace

Gas entering your furnace is ignited by the pilot light and burners heat the air.

Capacitor on gas furnace.

The first kind of capacitor is a start capacitor which helps the motor start up when you first turn on your heater. The capacitor in a gas furnace starts the blower motor but this operation is not in isolation. Turn off all power to the furnace. Flipping a switch and getting heat in your home requires a complicated series of actions by the parts of your gas furnace.

Your furnace uses a lot of energy so to supply the extra energy needed to power the blower gas furnaces have a capacitor. 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. They are generally divided into two types both of which provide electricity to the furnace apparatus at key times.

Power on and test the system. The blower then moves the warmed air into and through the ductwork in your house. The blower motor in your furnace blows hot air through the ducts and into your home. A start capacitor is typically found on an air conditioning unit or heat pump where extra torque is needed to start the compressor.

Touch the probes from the voltmeter to the terminals of the capacitor and see if the voltage matches the. Remove the blower housing inside the furnace to access the capacitor. What is a capacitor. Look for the voltage rating on the side of the capacitor.

Video of the day. Locate the capacitor usual close to the furnace motor. But with a bad capacitor your blower cannot function well and may put your family s comfort at risk. Your furnace uses a lot of energy so to supply the extra energy needed to power the blower gas furnaces have a capacitor.

Remove any bolt holding the old capacitor in place. Capacitors are a part of the fan motor in your furnace. A capacitor is a device that stores an electrical charge. Insert and bolt in new capacitor.

Remove the wires from the terminal and discharge the capacitor using the instructions included with your furnace. Hvac heating ventilation and air conditioning capacitors store electricity and help compressors and blower motors the systems that distribute hot. The capacitor will still hold a charge even without power. How replace a furnace capacitor.

Read on to know some of them. Take pictures of the wiring to reference back if needed. How to locate a furnace s start capacitor. A furnace usually uses a run capacitor to maintain a relatively constant voltage supply to the blower motor.

This is the star. A bad or faulty capacitor can exhibit many signs and symptoms. If you re concerned that your furnace capacitor isn t operating properly you can test it by following a few simple steps. Shut off the power to the furnace at the fuse.
