☑ What Does The Blower Motor Capacitor Do

Used in furnaces hvac systems and ac units of all varieties. For instance there are start capacitors which send signals to start up the motor and run capacitors that regularly send signals to keep the motor running.

The first kind of capacitor is a start capacitor which helps the motor start up when you first turn on your heater.

What does the blower motor capacitor do. Capacitors are a part of the fan motor in your furnace. The capacitor gives the blower motor a boost on start up to get the motor up to spped once the motor is running full speed it drops out of the circuit. The furnace blower blows hot air through the duct system of the home.

They are given different names to confuse the common homeowner. Hi heath my name isxxxxx removed the blower unit from the furnace to see if the motor was going bad because when it started up the pressure switch seemed to close because it seemed like the fan motor was pulling to hard when starting. If your motor has an internal centrifugal switch then you have a start capacitor.

It actually tells a knowledgeable person what type of motor is used. The blower then moves the warmed air into and through the ductwork in your house. Burners heat air entering the furnace.

Like a battery the capacitor stores the extra energy that is needed to jump start the furnace blower. It stores the extra energy needed to kick the blower into action. Extra energy is required to power the blower so its connected to a capacitor that works like a battery.

A faulty blower will 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. There is also a run capacitor.

Typically there is a capacitor assigned to each compressor outside fan and blower motor. Depending upon the motor design it can be a start or run capacitor. They are generally divided into two types both of which provide electricity to the furnace apparatus at key times.

Start capacitors have a higher capacitance than a run capacitor. There are multiple capacitors within a given ac unit.
