If the blower is made of plastic it does not have a set screw. You most likely need a new squirrel cage. They are formed to the shaft and have a compression ring that holds them in place.

The fan on the inside ac unit wont come on is there a reset button


One of the common problems in air conditioners is fan motor bearings going bad and the fan motor shaft is locked up stalling the motor or preventing rotation. Another cause of fan motors not running could be the motor start capacitor. The capacitor is needed to give the motor a jump start to get it rotating. If you can get access to the fan squirrel cage and can spin the fan ok, the motor bearings are then good. Most likely the problem then is a bad motor start capacitor that can be replaced. In very rare cases the motor winding itself could be bad and the fan motor will need replacement. regards, Dennis

How do I clean dryer squirrel cage?


To remove drum/fan drive motor:

• Remove rear panel & rear air duct. Remove belt from belttensioner. Remove top panel & drum if needed for better access.
• Disconnect terminal connector from motor, then remove two screws from motor mount & one screw holding fan to front shield. Lift rear of motor mount up and slide entire assembly toward rear of dryer.
• While holding motor shaft, not rotor fins, remove fan blade from motor shaft. Remove three screws, then remove fan housing from motor.
• Remove spring clamps by pushing ends of them down and away from motor. Lift motor up from motor mount.

Cage motor is the best blow out with compressed air. Also, by the way, clean the fan housing from the inside.

Rattling noise from under glove box when fan for A/C or heat is turned on is it the blower motor or the fan?


Your blower motor and squirrel cage (fan).

more then likely it is your plastic squirrel cage fan under the dash.
they are made of plastic and over time the lock nut or screw comes a bit loose and the plastic collet on the fan wears out allowing a lot of play between the motor drive shaft and the fan .


Or you may have had something fall through your defrost vents on the dash and down into the squirrel cage housing

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.

Why does my ac freeze up


Hello, air conditioners will freeze either due to low airflow.....such as dirty filter, dirty evaporator coil, weak or not running blower motor. Also, a low refrigerant charge can cause the unit to freeze up.

How do I clean a Hawaiian Breeze tower fan?


Unplug fan. Lay the fan face down. Remove the four screws holding the stand to the base. Slide the stand all the way off the cord. Look at bottom of fan and find the small half circle indent just to left of center. There is a screw there, remove it. Go to the hand grip at the top of the back and pry out the two white rubber plugs to reveal two more screws, remove them. Back cover can now slide downward. May take a little squeezing at the center of the grille where internal clip is. Remove two screws at top of squirrel cage. Turn squirrel cage and loosen screw at bottom collar on motor shaft. Tilt the top of the squirrel cage outward slightly and slide upward to remove the squirrel cage. You can slip upper metal bracket off and set aside. Motor is held in by two screws, remove them and flip motor out of the way. There are two screws below where motor sat that hold in base of front grille, remove. Front grille has a series of clips along edges, carefully pry them inward from bottom to top and push grille gently outwards. You can now clean the rear grille, front grille and squirrel cage in warm soapy water and allow to dry. While they are drying, use a vacuum and dust rags to clean interior. When parts are dry, reinstall front grille and reinstall 2 screws. Reinstall motor with two screws. Turn motor shaft so flat notch is pointing up. Recommend to spray a tiny bit of WD-40 or a tiny dab of moly grease on shaft at top of squirrel cage, then replace upper bearing bracket on top shaft. Slide collar end of squirrel cage onto motor shaft and align screw with shaft flat and tighten. Reinstall two screws at bracket at top of squirrel cage. Align back cover just a bit toward bottom, then slide upward and clips will snap into place. Reinstall two screws in hand hold area, then reinstall screw at bottom of cover at half circle notch. You'll need either a magnetic tip screwdriver or a pair of long needle-nosed pliers to get screw in hole before tightening. Feed cord back through base and reinstall 4 screws. It took me about half an hour to do this whole process on each of my two Hawaiian Breeze fans, but they now look brand new and run very quiet.

My heat and AC fan wont come on and all the fuses are fine


What I would do is pull the fan blower motor speed switch, plug the wires back into it while you're holding it in your hand, run the car, and check with a multitester and see if you are getting voltage at the switch. Should be something like:
High=12-14 volts
MHi=8-10 volts
MLo=4-6 volts
Low=2-4 volts
OFF=no voltage

If you get voltage but the fan still doesn't work, then it's either a bad ground, or the motor is bad. If you can access the blower motor wire connections(sometimes its easier to try this with it removed from the vehicle), then you could try jumping the blower motor at the wiring connection with a known good 12 volt source, and if you STILL can't get the motor to spin then it's seized up or it's just a bad motor. If you have the motor removed, try spinning the squirrel cage by hand. Is it stiff? Seized? Probably need a new one if it doesn't spin freely by hand.

Hope this helps!

The squirl cage on the dryer of my model LSE7806


Howdy,

Absolutely should be positively "locked" to the motor shaft. There should be a set screw in the collar of the squirrel cage mount. Either it is missing of has loosened. Please tighten (or replace) this set screw. Also, it is very IMPORTANT to make sure that if there is a flat machined surface on the motor shaft, that you align the squirrel cage (and set screw) so that the set screw will seat firmly and squarely against this flat surface. This design ensures that once properly aligned and set, that the squirrel cage will follow the motor shaft faithfully. Also, it is recommmended to apply some thread sealant (Locktite) to the threads of the set screw so this will not happen in the future. Vibration can be the cause of this.

Good luck,

J

Running not blowing air


sounds as if fan isnt attached to motor shaft. There is a set screw on the fan cage that if it loosens the shaft will turn inside of the fan not turning the fan( also known as a squirrel cage) You need to get access to the fan motor and see first if its shaft is rotating, if it is see if the squirrel cage is turning if not the set screw located on the inner collar of the squirrel cage needs to be tightened. Thie set screw is more than likly an allen set screw.
