capacitor stores charge ,so we use capacitor in fan for continuous voltage supply.
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.
bad motor or capacitor
No
How much to replace blower and capacitor on carrier 48gs030?
Function of Capacitor in Air Conditioner:Compressor Motor Capacitor: This air conditioning capacitor usually consists of two capacitors that are combined. This vital capacitor gets the motor running in the air conditioning unit.Start Capacitor: This capacitor provides auxiliary support and that is not a standard on every air conditioning unit. It can give the motor a boost to get it started.Indoor Blower Motor Capacitor: This capacitor is self-explanatory. It is responsible for starting the indoor-blower-motor and keeping it running efficiently.Outdoor Fan Motor Capacitor: The name says it all for this capacitor. It starts the outdoor fan and keeps the air flowing through the coils that run on the outside of an air conditioner.
If it is the outdoor fan, it could be a couple of things. 1. Bad fan capacitor 2. Bad fan motor 3. Loose wire If indoor blower the same apply, but it could also be a bad fan relay.
I use the gfk4 blower motor kit.
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.
Remove the wiring harness to the heater blower fan. Remove the retaining bolts. Remove the fan from the blower. Reverse the process to install the new heater blower fan.
If the heater blower has humming noise when motor is running, first check its capacitor. If the capacitor is fine, then the motor is the problem and may need to be replaced.
The blower fan motor is worn out.
