Furnace Motor Run Capacitor

The run capacitor is used with capacitor start run and permanent split capacitor psc motors.

Furnace motor run capacitor.

The start capacitor gives a fan motor the torque it needs to start spinning then stops. No coupons to display. If the capacitor isn t holding the charge needed to run the blower the blower may run slower and or hotter. The dual rated run capacitor is a continuous duty capacitor designed for use in air conditioning condenser units.

But with a bad capacitor your blower cannot function well and may put your family s comfort at risk. It saves space by combining two capacitors in one. While the run capacitor stays on giving the motor extra torque when needed.

Have two capacitors called a start and run capacitor. This will cause the motor to run slowly causing excess heat. Be sure to call your hvac professional. These do not have a start capacitor and rely only on a run capacitor to start the motor.

Furnaces can fall into three categories when it comes to capacitors. Have only a single capacitor. Such permanent split capacitor blowers start slower and quieter than models with separate start and run capacitors. Excessive heat in the motor can cause the motor to malfunction.

Hvac heating ventilation and air conditioning capacitors store electricity and help compressors and blower motors the systems that distribute hot air through the home with starting and. Not have a capacitor at all. 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. Basic precautions need to be taken mainly turning the power off to the furnace as not to get shocked.

A faulty capacitor will not be able to hold the charge necessary to run the blower motor properly. This can lead to a furnace motor problem. If you notice your furnace s motor cycling frequently you should test the capacitor. Its capacitor works like a battery and stores the energy needed by the blower to work properly.

Some units do not use a capacitors to run the blower motor.
