How can I fix a Frigidaire air conditioning unit that keeps filling with frost on the inside?

This is only low freon. If the bottom coils freezes and frost over, you don't have enough freon to travel as liquid back to the compressor and boils right there and past this only cool gas .I'll advise you to get this fixed before you loose a compressor due to locking up by not cooling the compressor properly. Get in touch with an Ac man. this should only cost around $100:00

eventually,cycling process is doing done if the thermostat sense the configure temperayure set up it will trigger to stop your compressor motor as well as the blower fan,blower fan independenly to you compressor.if your thingking that your compressor is tripping off,check your operating current on one line using clamp ammeter and compare to the rated current that tag on
motor compressor body,if the current flow is higher than the rated current specified on compressor motor,well problem occured it will trip your compressor,because overload protector is becoming your thermostat.but if you got same current result it was cycling process.If tripping off maybe air is present in your system call qualified ac tech, to purge out air in system.

The fan motor is getting hot and going off on the internal overload in the motor.
This is caused by either a low voltage, a bad capacitor, or tight or dry bearings in the motor.
To check the bearings turn the power off to the unit, then spin the fan blade if it spins freely then the bearings are ok.
To check the capacitor you will need some kind of tester or you can buy a capacitor and replace it, that's what a lot of people do. They usually don't cost very much.
To check the voltage you will need a voltmeter and measure the volts at the unit.

Dear sir we need sugation for this we having prob with compressure Crrier Package unit model no : 50TJ16-028B/S We having little Diffreance with power supply (each phase.like a Red is 217v ,yellow is 218v Blue is 221v ) is there any problem for compressure .pls give me u r idea

The unit has lost part of it's charge, and will need recharged. For that reason a leak must be found and repaired or it all will reoccur again.
