SOURCE: Fridge stopped working suddenly
Sounds like the relay (start device) on the compressor has failed. This is a very common problem especially for models that are 3-5 yrs old. I would replace that first.

Ended up having a freon leak in tubing around door. Luckly the warranty was 5 years in sealed system. New one was FREE.

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.

If anything, it appears undercharged. Purging is not recommended. @90 degrees the high side corresponding pressure is 168.4 and Low side coresponding numbers re70psi/68degrees. With all due respect to the tech I think . If your room temp is 80, the corresponding high aide pressure is 143.6 , Low side 85 psi Yup, undercharged. Now do me a favor and don't start any "but he said" wars going. If anything, Just call him back and tell him something is still not right. Ask him to bring you a pocket rergerence for temp/pressure relationships. The numbers I gave you are for R-22 which is commonly used in residential applications. Well, good luck and keep your cool. IDon't purge. R-22 is very expensive asis everything else. You may want to dispute anny additional service call charges. Good Luck

How To Test the Compressor Relay
The compressor relay's purpose is to
start the compressor. A faulty relay can result in the compressor
failing to cycle on. The relay is accessed from the lower rear of the
relay is located in the terminal box which is located at the side of the compressor.
Before testing a compressor relay, unplug the refrigerator to avoid an electrical shock hazard. Also, if the compressor uses a capacitor, it must be discharged first to avoid the risk of electrical shock.
Beneath the terminal cover is found the compressor relay , overload protector and the electrical terminals of the compressor motor.
Remove the compressor relay by pulling it straight off from the compressor.
Pull the wire off of the side terminal of the relay. It is connected with a slip on connector. Firmly pull the connector, do not pull on the wire. You may need to use a pair of needle-nose pliers.
Inspect the connector and terminal for corrosion. If either is corroded they should be cleaned or replaced.
There are two types of relays you may encounter, wire coil and solid state. If the relay has an exposed wound wire coil it can be tested for continuity. Otherwise, the relay is of solid state design and requires specialized equipment for testing.
