Some AC motors are designed to start running as soon as electricity is provided. Other AC motors are designed for a specific purpose and do not start on AC current. They will RUN on AC, but require a DC current to start. Here's where the capacitor comes in. It stores DC power that, when released, starts the motor turning. At this point, AC current will nicely run the motor.
It stores electricity used as a boost when first starting the fan.
capacitor stores charge ,so we use capacitor in fan for continuous voltage supply.
A capacitor add torque to an electric motor that is designed to use them, they are called PSC or permanent split capacitor type motors. the capacitors terminals go to the Run and Start windings.
We use capacitor on fan motor or blower to create phase difference between two winding(Starting & running). This phase difference introduce starting torque on fan motor. Otherwise without capacitor the torque produced in positive Half cycle of AC supply is nullify by the torque produced in negative half cycle.

disconnect the electrical connector from the blower motor and remove the 3 screws from the blower motor housing.pull the blower motor and fan straight down. to remove fan from blower motor,squeeze spring clip togetherand slip fan off the shaft.some models have no clip or screw holding fanto shaft, in this case use 2 screwdrivers to pry it off.install fan onto blower motor housing and install blower motor into the heater housing.
Not all pool pump motors have both start and run capacitors. Many single-phase pool pump motors use a start capacitor to help initiate the motor's operation, while others, particularly permanent split capacitor (PSC) motors, may only have a run capacitor for continuous operation. It's essential to check the specific motor type and design to determine its capacitor requirements.
# Disable the airbag system before working # Remove the lower right dash insulator panel for access to the blower motor # Disconnect the electrical connector from the blower motor and remove the three screws from the blower housing # Pull the blower motor and fan straight down # To remove the fan from the blowr motor,use a narrow punch and tap the shaft out of the fan assembly.
remove panel under glove box. slide bcm to one side. ( it is much easier if glove box is removed ). remove 3 screws from blower housing. pull the blower motor and fan straight down. disconnect the blower motor electrical connection, if you are replacing blower motor with a new one, use old blower fan from old one.
if it is the same number on it!!
