Furnace Motor Run Capacitor

Most modern day furnace blowers use permanent split capacitor motors.

Furnace motor run capacitor.

The run capacitor is used with capacitor start run and permanent split capacitor psc motors. No coupons to display. The start capacitor gives a fan motor the torque it needs to start spinning then stops. Not have a capacitor at all.

Be sure to call your hvac professional. Furnaces can fall into three categories when it comes to capacitors. Basic precautions need to be taken mainly turning the power off to the furnace as not to get shocked. While the run capacitor stays on giving the motor extra torque when needed.

The blower motor in your furnace blows hot air through the ducts and into your home. This can lead to a furnace motor problem. Have two capacitors called a start and run capacitor. If you notice your furnace s motor cycling frequently you should test the capacitor.

This will cause the motor to run slowly causing excess heat. But with a bad capacitor your blower cannot function well and may put your family s comfort at risk. 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. These do not have a start capacitor and rely only on a run capacitor to start the motor.

If the capacitor isn t holding the charge needed to run the blower the blower may run slower and or hotter. A bad or faulty capacitor can exhibit many signs and symptoms. Its capacitor works like a battery and stores the energy needed by the blower to work properly. Excessive heat in the motor can cause the motor to malfunction.

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.

Some units do not use a capacitors to run the blower motor. A faulty capacitor will not be able to hold the charge necessary to run the blower motor properly.

Such permanent split capacitor blowers start slower and quieter than models with separate start and run capacitors.
