i checked to coil and its fine. i went through the display settings and still no cold air. i hear the compressor kick on and i have a steady stream of water discharging. i took the fridge out and everything looks good. all electrical connections look good. at this point i have to assume that i need R22 in the system. trying to find someone to service it is almost impossible. any more input would be greatly appreciated. thanks for the manual link it was very helpful. thank you to all.
