Whirlpool Beverage Center (WBC127BLS) - Won't cool enough
If you're handy with a soldering iron, it's possible to 'trick' the fridge into cooling down a few more degrees.
If you open the door to the fridge, on the right wall near the bottom is a small plastic grate. You should be able to pull this straight out from the side wall. There is a temperature sensor attached to the back of the grate. Unplug the sensor. (The fridge will then give you a very annoying error beep and display "EE" on the readout. Pushing the °F-°C button stopped the beeping.) This sensor will change resistance with temperature. (The lower the temperature, the higher the resistance) I was reading a resistance of about 3700 ohms at 43°F and 2460 ohms at 68°F. Throw in a rough assumption that the response is linear and it works out to almost 50ohms/degree. In order to 'trick' the fridge into cooling down more, you need to drop the resistance. I was aiming for about 6 degrees cooler. Assuming the resistance response was linear, 6 degrees cooler would give me about 4000 ohms from the sensor. By jumpering a 50000 ohm resistor (yes, 50K ohm) in parallel with the sensor, I should get about 6 degrees cooler. I did the soldering, plugged the sensor back in, and ended up about 8 degrees cooler. Two days so far, everything appears good and the beer is cold.
Put a 50K ohm resistor in parallel with the temperature sensor behind the grate on the inside right hand wall.
The temperature read out will be inaccurate forever after though. But then, I just want cold beer, my wife wants cold water, and the kids want to play with the cool blue light. I don't care what the number on the readout is.
