Is the wine cooler compressor running currently? If not, feel it briefly with the palm of your hand. Is it exceptionally hot?
It was not running first thing this morning. I shut it off, then power cycled. It came on and ran. Right now it sounds like a motor is trying to start, then stops. Coming from front left bottom of unit. It is warm. Can hear the click of a motor relay, it makes a creaking sound, then cycles off. It keeps repeating every 15 seconds
Subzero came out last week. They agree it is sealed system problem. He ran onboard diagnostics and could not get to the required temperature in 5 minutes. He did not have his gage set with him (really???). Another guy is coming back tomorrow morning to check pressure and die check for leaks. They suspect one of the evaporators in the cooler is bad. Will order the part and come back. They say it is a half day job. Lots to pull apart. I will update you once it is fixed for your own reference.
Leak is probably either in the evaporator or heat exchanger. Surprised he didn't have his gauges with him. Kind of strange, but keep me in the loop.
