I used two Inkbird digital temperature controllers. Cut the thermometer out of the air conditioner, rewire so one controler turns on/off the compressor, and the other turns on/off the fan. Temperature sensor for the fan reads temp inside cooler. The other sensor sits on the cooling coil. If coil temp approaches freezing, the compressor shuts off, while fan continues to run. No light bulb trickery needed. Maintaines about 4 degrees C Used air conditioner = $50 2 controllers @ $25 each = $50 Built a 4x6x6 stick frame box with 2x4 lumber and sheeted with plywood. Insulated inside it with 2 inch blue foam panels. Total investment = $700 It's on feet so a palet jack can pick it up and move it. Walls, floor and ceiling are separate panels for disassemble/reassemble ease (never done in 4 years).
I agree with @stevehatcher3228 I built one 7 years ago and the second sensor on the coil to kill the compressor and let the fan de-ice the coil is needed. Coolbot has the same feature and I copied it when I made my close. I got a video on my page of my setup but use a JCI freeze sensor, but either works as long as you can sense the coil freezing. If not it will over work and trip the breaker. Doing the second sensor will avoid the temperature step cooling you are doing now.
Yup you are the man!

Thank you. Keep Farming!
For my 4x8 walk-in I daisy chained 2 inkbirds together. The 1st one has the sensor in the fins set at 32°. The second one is set at 39° and turns off if the first one freezes. I got a deal on 4'x8'x3.5" polyiso (roof) panels for $300

Great plan! I had a similar Idea for my side curtain control to have it go up at one temp and down at another.
You say 40ish degree for the potatoes? Does that start to convert the starches to sugar at that temperature? Also do you leave a bucket of water to increase the humidity? Or how long do they stay at that temperature for you before they start sprouting?

The fridge stays around 45'F. No water, no sprouting in December.
