I have a wine refrigerator set up as a fermentation chamber with a Johnson A419 temp control. It's worked well for me for the past year, and I'm able to keep my fermentation temp within 2 degrees of my target. My problem is that I can't get it below about 42 degrees, as the built in thermostat is only made to go down to about 45. I'm curious if I remove the + and - leads from the T-stat and connect them will it effectively take the built in T-stat out of the loop and allow the compressor to stay on longer to get me down to lagering temps? Is this risky at all?
There are also a couple of other leads connected to the thermostat that turn the light on and off. Do I need to worry about these? I can post a pic of the wiring going into the the thermostat if need be.
Any help is appreciated!
