I use a mechanical 5k btu window air conditioner for my fermentation cabinet. The cabinet is about 40 cubic feet. I've bypassed the thermostat by wiring the inputs together with a wire nut so that the compressor will always run when the unit kicks on via the STC 1000.
My problem is that it can't seem to get my carboys down to the proper temp. They are hovering around 21.5C, whereas I'd like them around 19C or 20C. The air coming out of the blower vent is cool, but I wouldn't call it cold. It may be no cooler than 21C, but I haven't figured out a way to tell directly.
The unit had been running for a long time yesterday. So I decided to open it up to see if anything was obviously amiss. Other than the compressor being extremely hot, everything seemed in order from a visual inspection.
Any suggestions on diagnosing the problem?
