I've heard many times you can kill your compressor with too much cycling. I "think" I killed mine because of it. I've been told to do at least a +/-2F set point. I have my Ranco probe in a 6" thermowell inside the fermenter, so that limits it. In my serving chest I have the probe directly in a 1.5L bottle of water with a tiny bit of bleach.
At least now during winter I can use the fridge as a fermentation area and have the Ranco on the brew blanket to +/- 1F set point.
And there was an article in one of the most recent BYOs about using the Love to directly control the thermostat of the fridge. Doing this lets you keep the light working, and he also wired in an outlet, so he could run his stir bar in the fridge without running more wires through the door gasket. I think it's cool, but am not sure it's worth taking the fridge apart to save having an extension cord and the Ranco probe wire going through and slightly displacing the door gasket...
