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 to replace an indoor fan motor on an Airwell air conditioner?


There will be a set screw on the shaft accessible either through the end of the blower wheel opposite the motor or through a notch in one fan blade that lines up perfectly with the set screw. If there is a notch in the blower wheel, it will take a long allen wrench to reach the distance to the wheel hub. But you can use a short angle type when you have the assembly removed and sitting on the floor. The other type usually has a 5/16" square headed set screw securing it to the shaft.

Check for rust on the shaft and if it is covered, sand it shiny with sandpaper prior to attempting to slide the motor out of the squirrel cage hub. A little WD-40 really helps.

How do i remove the squirrel cage type blower fan.


Most fans of this type have a cover between the motor and the actual fan. The cover is usually metal, sometimes plastic and usually has 4 or more screws holding it down. Remove the screws and the fan and cover will come out as one assembly (Sometimes there's a rubber seal between the cover and the housing that may be sticky you may have to gently pry up around the cover to free it from the base its screwed down to). To remove the motor you need to remove the squirrel cage from the shaft, then the cover can be removed and the motor replaced.

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.

Ac squirrel cage fan motor noise


Could be bearings going out, or a squirrel cage rubbing the blower housing, a squirrel cage blade that came loose, or a capacitor.

Take a long time for blower motor to get up to speed


The first thing I would do is to clean motor and squirrel cage. It would be best if you would remove it and take it somewhere that you had a air compressor to blow out motor ports and fins on squirrel cage. Most of the time you can remove by disconnecting modular plugs and removing two or more screws on rail that squirrel cage slids on.
If you can get it out you can use a fine wire brush to loosen dirt and dust from fins on cage then use air to blow out as much as you can.
Your motor may be getting worn so check the bearing by grasping cage and see how much it will slide side to side and if it moves more then about1/8 inch then you are going to need to replace it before much longer. Also make sure that the rim of squirrel cage is not rubbing on blower housing and if it is then loosen motor mounting screws and adjust ,then retighten screws.
I hope this helps you. Thanks

Same problem, can't open up the fan


ARE YOU TRYING TO REPLACE THE MOTOR OR THE FAN BLADES. YOU SHOULD BE ABLE TO REMOVE THE TWO SET SCREWS FROM THE SHAFT AND PULL THE MOTOR OFF THE SQUIRREL CAGE

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.
