Hi, Reduced air flow, low on freon or being continuously run during cooler weather such as at night. Some people turn their thermostat on 60 thinking that it will help get it cooler faster. They freeze up at night and don't get a chance to thaw during the day. It needs set no lower than 75 or so. The evaporator may be dirty. Don't know a lot about your particular unit but if the outside unit has the compressor and refrigerant lines running to it, The large refrigerant line should sweat all the way to the compressor if its fully charged. Please rate me if I have helped. Good luck kstfas

Low voltage shorts can be a real pain to find!!! i would try a process of ellimination: first i would try to elliminate the thermostat. then id look for a wire that is vibrating on something in the cabinet.

SOURCE: squealing and sometimes doesn't blow cool
A squealing noise is most likely the bearings going bad in the blower motor. This will slow the motor down. If the blower is not operating at the proper speed this will affect the temperature pressure relationship of the refrigerant. This will cause the unit to put out the wrong temperature. Running the unit to long under these conditions can possibly cause further problems ( including a very high electric bill). I recommend that use do not use this unit untill it is repaired or replaced.
Good luck.....

likely is the thermostat or could be the compressor going out on over load compressor runs blows cold air trips out on the over load fan will stay running jumper out the thermostat see if it stays running.like1/2 hr. if it does replace the thermostat not hard to change if you can find one.Tom
