Hi there!

This is almost certainly a dry bearing on the fan motor. If there is little or no oil on there, a little rust may form and the next time this is powered up, the rust comes off - but is polished onto the bearing - creating the squeek.

Buy a can of maintenance oil in a pressurised can, and squirt some on the bearings at each end of the motor. It doesn't matter if it drips or runs down anything. If there are 2 separate motors - you need to oil 4 places.

If the unit is very old, it may use a motor with brushes. I'll give more details if the oil doesn't work.

Thanks for using Fixya - and if this works, please rate as such.

Lg ac shaking violently when turned on

Sounds like your fan motor is coming loose from the mounts or your squirrel cage is loose or loosening. That's just the air handler, the compressor is outdoors in the condensing unit. Pull that air handler apart and find out what's causing it, or shut it down. This can hurt you if the fan flies out of there.

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.

Cooling cycle. Severe vibration of interior unit. Loud 'whooshing' at warm air return. Noticed small pool of clear liquid with a bluish crystallization near angle joint in PVC overflow...

sounds like your condensate drain is clogged, the whooshing sound is probably due to the water that is in the pan, it also sounds like your squirrel cage is out of balance, or you have a broken mount, the installers "should" have put a cleanout tee in the main line to the condensate, if not you will have to cut the line and install a tee to pressurize the drain and blow it out, as for the blue.. sounds like they used the "wet dry" pvc glue that has primer built in and were just messy when they installed the drain.
Remove power from the system, take the screws out of the coil housing and look at the drain pan, verify that it is indeed full and not draining properly or that it is leaking and is running water out of the pan into the ducting.(not good) unclog the drain and install a cleanout tee for future.
the squirrel cage or mounts will be physically visible if mount is broken or cage is out of balance..this needs to be accomplished with the blower door off and the unit turned to "fan on" at the thermostat, physically depress the safety switch and visually verify the problem... Hope this helps Dan

My Goldstar has started squeeking... not vibrating... squeeking. Any suggestions? It sounds like something needs some WD-40 sprayed on it.

sound to me like the fan motors squeeking may need a little lube these motors are sealed to protect them from the elements it is possible that a lube port exsists on rear of the motor it will have a little plastic plug in it you can oil it there. a good one to use is zoom spout oiler hardwre store may have it wd 40 not good for this app. wont last. if not an old trick i do is tilt the unit with the shaft and condenser fan facing up and put just a couple drops on the shaft you will see it run in DONT USE TO MUCH CAN DAMAGE MOTOR so be careful this should help.

When turn on fan sounds like it need greasing and

If you are refering to the indoor blower, you need to shut off the ower to the unit, open the blower chamber and check the cleanliness, build up of dirt and debris in the squirrel cage can sometimes cause vibration. Check the "end play and see if there is considerable play in and out on the motor shaft, also check the mounting brackets to verify the intergity of the mechanical connections. If it is a belt drive, it could be the bearings, the bearing mounts or the cage itself if it is belt drive then consider changing the unit as it is well past time!

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.

Rheem A/C unit makes a clicking sound when

Shut down the unit and turn the power off. Take the cover off of the blower housing and feel around within the squirrel cage. It sounds like something may have been drawn up into the blower. Also it is possible that the blower wheel might have thrown a balance weight and caused the wheel to become unbalanced. It could also be the motor about to go out but since I can't hear it myself, I'm trying to cover all the bases.
