How to replace blower wheel on Friedrich SL28M30 AC unit


follow this steps and fix it. God bless you








    • 1



      Turn the electricity to the air conditioning unit off at the
      service disconnect box. Follow the wires from the AC unit to the
      disconnect box, usually located next to the unit. Open the disconnect
      box and, depending on the type, either pull the buss-bar or flip the
      disconnect switch.





    • 2



      Open the air handler\'s access panels with the correct size of nut driver, usually 5/16- or 1/4-inch. Save the screws.









    • Remove the control panel\'s cover, if equipped, with a nut
      driver. Some models have a flat metal cover over the electronic
      controls, and some control panels butt up to the unit\'s access cover.
      Save the screws and access cover.





    • 4



      Follow the wires from the blower motor. Two wires will go to
      a capacitor located on the blower\'s housing. The rest of the wires will
      go to the control panel.





    • 5



      Cut the wires leading into the control panel with wire cutters. Leave the cut wires connected inside of the control panel.





    • 6



      Remove the retaining bolts with either a nut driver, usually
      3/8-inch, or an adjustable wrench. The retaining bolts, found on the
      mounting brackets that the blower\'s housing slides on, keep the blower\'s
      housing locked into position. Save the bolts.





    • 7



      Slide the blower motor\'s housing out of the AC unit. The housing will slide straight out along the mounting brackets.





    • 8



      Disconnect the two wires going to the capacitor. They will pull straight off the capacitor\'s terminals.





    • 9



      Unscrew the squirrel cage\'s locking-screw with an adjustable
      wrench. The squirrel cage, the bladed wheel, connects to the blower
      motor\'s shaft inside of the housing. The locking screw holds the
      squirrel cage to the shaft.





    • 10



      Unscrew the blower motor\'s mounting screws with either a nut
      driver, usually 3/8-inch, or an adjustable wrench. These screws hold
      the motor to the housing and are found on the opposite side of the
      squirrel cage, the same side that the wires leave the motor.





    • 11



      Pull the motor from the housing. A drop of oil on the shaft
      will aid in removal. If the squirrel cage sticks to the shaft, then hold
      the shaft still with an adjustable wrench while spinning the squirrel
      cage on the shaft.





    • 12



      Slide the new blower motor into the housing. The blower motor\'s shaft will slide into the squirrel cage\'s hole.





    • 13



      Tighten the blower motor\'s mounting screws.





    • 14



      Spin the blower motor\'s shaft until the flat part of the
      shaft lines up with the squirrel cage\'s locking screw. Move the squirrel
      cage in or out until it does not touch the housing or the blower motor.
      Tighten the locking screw.





    • 15



      Connect the blower motor\'s capacitor wires, usually brown or
      brown with white stripes, to the capacitor. Direct replacement motors
      use the same color-coded wires as the original.





    • 16



      Slide the blower motor\'s housing into the AC unit along the mounting brackets. Install the mounting bracket\'s retaining bolts.





    • 17



      Connect the new blower motor\'s wires in the control panel
      one at a time. Disconnect one old wire in the control panel. Determine
      its color and connect the new wire, of the same color, to its place. Do
      this for all wires.





    • 18



      Replace the control panel\'s cover, if equipped, and the
      unit\'s access cover. Turn on the power to the unit at the disconnect box
      and test the blower motor.
