It sounds like it could be low on refrigerant. without refrigerant it will be loud and it will not sweat. However it could be restriction in the refrigerant lines that will not allow the refrigerant to move. This will have the same symptoms. Both solutions sound like a job for a licensed technician.

Aircondition wont turn fan

Make sure the set screw holding the blower wheel to the motor shaft is tight.
Try replacing the run capacitor for the fan motor if that does not do it. (If the motor shaft turns and the wheel turns, but squeels real loud, then replace the wheel if the set screw is tight.)

Very loud when fan is running

This is likely caused by a faulty blower motor bearings, or the fan has something in it or it could possibly have broken. Shut down power to unit, remove cover and inspect the fan shaft, blades, and spin it. it should freely spin. If it hangs up you likely have a bad blower motor.

Condensation buildup

Make sure the unit tilts towards the outside. If it's installed level or tilted toward front it will not drain properly.

Makes a very loud sound when in the final spin cycle. Model MAH5500BWW

The sound of the tub spinning is a smooth and not ruff sound. and with speed it sounds like a 747 taking off ( when your inside not outside ) when the brgs go bad it will sound like a train on the tracks when your waithing to cross. ( very loud as it speeds up and very ruff. if you remove the 4 screws in the back can ck just below the center shaft. there may be brown water stains on the base frame . / water has got in the main brg . and the brg's are failing . hope this helped. mm. ( could be the drain pump / ck for coins ect. drain pump runs just before and during spin/ but not soloud like brg's.. **** .

It seems it's collecting water in the tray and blowing it out through the top vent, dripping from the bottom inside the house and is making a sound constantly like the fan is hitting water as it blows.

AC units do take the humidity out of the air and water collects in the bottom. The unit should be tilted slightly downward on the outside so that the water runs outrside. Make sure the drain holes are clear. The pinging noise is common, the fan is hitting drops of water, nothing to be concerned about

Freezer making a loud noise.

Sounds as if the evaporator fan has shaft play or the blades are out of balance or striking something. When you open the door the pressure is equal but with the door closed the fan needs to push the air through the evaporator and return again and circle through fan again. I think soon would be a good time to unplug the refrigerator and remove the back panel covering the evaporator and fan motor to inspect the fan, shaft play and the evaporator for frost buildup or any obstruction of air flow.

Air conditioner is emitting condensation through top of unit

The manual said to remove the rubber cap on the back, exterior, of the unit, insert the drain plug and push down lightly to drain off the excess water accumulation. However, a drain plug was not included in the package. Furthermore, there wasn't an actual "hole" in the unit to insert it. I did drain what I could by just leaving the cap off. This did not take care of the problem completely. Next, I unscrewed and removed the the front, interior, of the housing unit. I then noticed additional water buildup in the bottom of the unit under the sling fan. I could not remove the fan, so I used a turkey baster to **** out what water I could. I know - resourceful don't cha think! Then pushed paper towels into the bottom of the cavity to absorb any leftover water. Whaaala - problem solved.

Thanks for your prompt response.
