I have a Haier dual zone wine cooler model wc200gs. The unit would not cool but I had made the mistake of not cleaning it out properly. I cleaned it with a air compressor but the unit still would not cool. I let it set for a couple of days, powered it up and it brought the temperature right to the settings I had set for it, however after a couple of hours it quit and the temp went up to 75 for both the upper and the lower.

I then did some basic troubleshooting and then replaced the thermal relay and overload sensor (cheap enough to try) and since then the unit has stayed what I would call “somewhat normal” but there are times when the bottom will go up to 60 but then it will cycle back down to 43 where I have it set. Any ideas on this. The upper seems to be stable around the 53 degree range sometimes varing about 2 degrees.

The compressor is warm but not what I would call hot.

Any ideas?
