The fridge was working fine until yesterday

If there is no frost build up on the inside rear freezer wall , the the problem is the overload/relay ( pt # 12002784 ) which is plugged onto the side of the compressor and is easily replaceable . Only 3 wires are connected . If there is a frost build up , then reply back , for the instructions on how to check for defective parts in the defrost area (only 3 ) .

seems the compressor went bad. time to get another frig.

The defrost timer may have stopped in the defrost cycle and if it isn't getting out of it then it needs to be replaced.  You can fins the defrost timer at the back  it is a box about 6 X 4 X 2 inches  you can use a slotted screw driver and advance the timer  see if everything works.  If it does work then replace the timer or see if it comes out of the defrost cycle within 30 minutes.
