I have a beverage cooler that I'm trying to modify to make the internal temperature colder.
The internal digital thermostat only allows me to set the temperature down to 39degF, and I'd like to have the temps about 5-10deg cooler.
I know the compressor is capable of pushing temps below 39degF by wiring in a completely new thermostat, but I'd like to try a simpler/cheaper approach.
I came up with the idea of adding a Potentiometer to the thermostat's thermocouple, in hopes it would allow me to adjust/calibrate the Ohms coming back to the circuit board... making the thermostat think the internal air temperature is warmer than it actually is, and forcing the compressor to continue cooling past the 39degF mark.
I made a basic diagram that shows what i was thinking, but that is as far as my elementary knowledge of electronics has taken me. I am unaware of the potentiometer type I would need, or if this would even work.
Hoping someone can lend some advice or push me in the right direction regarding this project! Thanks!
