Hi, my name is ***** ***** I have been in the home improvement and repair field for 20 years. I will be very glad to help you today. If the compressor is quite hot and it is running but not cooling the diagnosis I'm afraid is not good. There is low refrigerant which is caused by a leak. You may find oily substance on the coils that would help determine where the leak is but all of this does not help much since the cost of repair will be quite close to replacement unless you're certified to purchase and repair coolant leaks.
Unfortunately coolant is not available to purchase unless you're certified.
Hello, my name is George..Can I ask, aside from the internal fans, have you checked the tangential fan underneath the cabinet front that cools the compressor.. These have a habit of failing and causing the temperature inside to rise
To view it, take off the panel under the door at the front.
