bypass electric thermostat in wine cooler

Hi all,
I'm hoping this is the right forum to ask this.
I have a wine cooler that only goes as low as 54 degrees. I wold like to use it as a beer/soda fridge as well, but 54 is way to high for that.

The cooler (Emerson model FR966T) has no compressor but a power source/temperature control board. Here is the wiring diagram - (Page 8 of Emerson Beverage Dispenser FR966 User's Guide | ManualsOnline.com) and I have attached a picture of the board for reference.

Can anyone tell me what I CAN do to bypass the temperature on this so it can drop to at least 36?

Thanks in advance.

 

Unlikely you will get this to work the way you want. It uses a thermoelectric cooler and it's pretty clear from the manual that the best it can do is maintain about a 20 degree differential between ambient temp and inside temp (77 to 56). So you might get it to go to 36 if you kept it in a 55 degree room, but that's hardly practical. Of course, even to do that you would have to defeat the temperature sensor since the electronics limit lower setpoint to 56. Easiest way to defeat it would be to move the sensor out of the cooling chamber to the outside so it just runs flat out.

I think you'd be way better off searching for a used fridge on craig's list or buying a cheapy mini-fridge.

 

CT raised a good point about the amount of temperature differential you can expect with this type of cooler.

If you did want to mess with it.... you'd need to measure the DC voltage at the sensor when the unit is warm and again when cold. By modifying that resistance changes the regulating temperature.

 

Thank you both for your help. I have a feeling that my time would be better spent selling this and buying a small beer fridge!
