can anyone tell me if its possible for me to install a fan motor on my cenral air unit?

Question

Had it looked at today said it would cost $400 to fix it. Called sears for the part its only $91

Answer 1

If you have any common sense at all it should be easy.$309 labor sounds way to high in wouldn't take 15-20 min. to do the job. If you need any help e-mail me I don't care to help.

Answer 2

O yeah, it shouldn't be a problem at all. Disconnect the power first and then you should be able to go all out at it. My central unit has 4 sheet metal screws holding the grating on the top of the unit. Once those are removed the motor is fully accessible. It should just be a matter of disconnecting the old motor and unmounting it, remove the fan blade assembly and put it on the new motor, remount the motor and wire it up. I would guess that any one that has some no how can do it. I hope this helps.

Answer 3

I would replace the $6.00 run capacitor first.
Two of the wires from the motor go to this little dude and if it is out the motor won't run. The unit has 2 fans. One is outside on the condensing unit and the other is the blower that blows air over the coil to put air into your house(usually inside in closet or attic if not a package unit). If it is the condenser fan outside you need to turn off the power to the unit at the disconnect box. Most likely on the wall outside by the unit. Remove screws and top of unit that has fan mounted on it will lift up. Disconnect wires and remove motor and fan from top and then remove fan from motor shaft.

If it is the blower fan that blows the air inside you need to turn the power supply off. The housing that has the blower in it can be removed usually by loosening 2 screws and sliding out. It's a little trickier. The set screw that holds the cage onto the motor shaft will have to be loosened and the motor unbolted from the housing and the wires disconnected.
Take motor to supply company so you get the correct replacement. You will probably need a run capacitor also.
HVAC UNITS RUN ON HIGH VOLTAGE AND PULL HIGH AMPS. ELECTROCUTION CAN OCCUR. MAKE SURE POWER IS OFF!

Answer 4

If you know basic electric wiring such as replacing a light swithch ro light ficture you can probably do it. Be sure to disconnect the power to the motor.

Answer 5

Most aren't to tough to change out. Make sure you shut the power off to the unit and remember how it came apart! Make sure you change the capacitor also! Good luck!!
