refrigerators dont come with shrader valves. U must buy a clamp on or weld one on the low side. The clampons are not expensive and are called Bullet piercing valve BPV 31 and fit 3 sizes. Unfortunately u also have a leak somewhere. Most refrigerators use either R12 or 134a If you need further help, reach me via phone at https://www.6ya.com/expert/gary_9c859f4aa7e5ab10

Do you have any technical background? There is a simple and sure fix to this but you will need to be able to read a wiring diagram and have basic electrical tools like a wire stripper and electrical tape.

It is not design to do it

This site has your product manual for your dispenser but it is very vague on trouble shooting the cooling system.
In general, the compressor is controlled by a thermostat that is usually located in the conditioned space. It cycles the compressor on and off based on the sensed temperature and the setting that it is adjusted to.
So, let's talk in general refrigeration terms. Where the compressor is located, is there a fan? If so, is it running? That fan is usually the condenser fan and is wired to come on anytime the compressor is supposed to be running. If the fan is running and the compressor is not, then there is an issue with the compressor. If the fan is not running and the compressor is not running, then there is an issue with either power or the thermostat. If the compressor is running and the fan is not, then there is an issue with the fan.
This is a good starting point. Let me know if I can be of further help.

If the compressor is getting hot then the compressor is gone. But the price on a relay is fairly cheap so you can at least try it and if it doesnt work then return it and dump the unit. But like I said before when a compressor gets hot it means that the piston is bad and the rings are burnt and the oil is bad in the compressor.

Well, the old screwdriver through the evap trick huh?. you planned on repling evap coil and recharging with 134 a? correct??if you have that knowledge and ability then installing a charging port would be least of issue. sorry for sarcasm but not a do-it-yourself fix honestly bring it down to a local repair guy
