Wine cooler temperature control

This is a two zone system - one side seems to be about 4-5 degrees cooler than the setpoint, but still regulates around the colder temperature. The readout flips frequently up and down one degree. Are these normal, or signs of problems?

Thermostat on wine cooler


Well, I'm not sure what your actually trying to do, but the whole purpose of a wine cooler is to cool, not to freeze and the temperature should really get no colder than 34 degrees F.

I purchased a 52 bottle kitchen aid wine cooler. No matter where I set the thermostat, it is always 45 degrees and readouts are sideways "T's" instead of numbers.

The beverage center and wine cellars have a temperature display for each zone. 12 volts

AC is supplied to the display board from a transformer in the unit compartment. The displays are only temperature displays and have nothing to do with any cooling function. A thermistor is used to sense temperature for each zone. The thermistor for the bottom zone is located inside the lower portion of the separator. The thermistor for the top zone on the wine cellar, (mid zone on beverage

center), is located in the upper portion of the separator. The thermistor for the beverage center upper zone is located on the inside of the 2-piece evaporator cover. It is on the right-hand side.

The mid temperature for the bottom zones on either unit are 60? Fahrenheit plus or minus 5 degrees. The mid temperature for the mid zone on the beverage center and the top zone

on the wine cellar is 45? Fahrenheit plus or minus 5 degrees. The mid temperature for the

top zone on the beverage center is 38? Fahrenheit plus or minus 5 degrees. I think at tis time you should check each section with a pocket size digital thermometer to cofirm tha the mechanical thermostat is within calibration. Click Here=> 4344690 Temperature Control

I believe the problem may be in the PCB transformer shown at the bottom right corner of the wiring diagram. It is possible o change the transformer but I have not been able to find the board that powers the LED temperature readouts. If needed let me know and I will call Whirlpool mfor you, Thanks, Sea Breeze

Viking Wine Cellar Temperature Near-Freezing


Viking wine coolers are made by Marvel.They all had issues with freezing the contents. If you replace the electronic cold control system it will be fine.If you don't, it will freeze the wine popping the corks and leaking in the unit.If you get the parts from Marvell they are much cheaper.

Chamber wc902 wine cooler which wont set temp


I have the same issue especially when there is a power outage. To reset it, press the preset until "1" appears, then adjust the temperature as low as it will go by repeatedly pressing the temperature "-" button. Usually works.

Haier Thermoelectric Wine Cooler


Hi, Well not much to go on but this is not a complicated unit. Please bear with me as we go back and forth for this type of long distance troubleshooting. The control board on this type of unit uses ambient temperature and that is what should be displayed when first turned on. Knowing that; the unit will not run if the setpoint is lower than the ambient temp. The unit operates on 27F degree difference from ambient. So lets do this, unplug the unit, remove your stuff if any, open the door for a couple hours till the unit stabilizes to room temp. Close the door, plug the unit back in and note the display. Move the setpoint to just below whatever your room temp is, if there are dashes it indicates a temp problem or the sensor that needs to know the difference. Good for now, let me know. Thanks and Good Luck!

COOLER TEMP CONTROL SEEMS NOT TO BE WORKING.  TEMP GOES DOWN TO 42 AND STAYS THERE.


thats because 42 degrees is the optimum temperature for wine to be at. unlike other beverages wine coolers only go to 42 degrees.

Three Temperature zones


Did you read the owners manual? It will be kind of hard to tell you because there are so many different settings for different areas.

Danby wine cooler


Is it because your keypad not functioning, meaning does the number change when you press the arrow up or down? Or when you set it, (let's say 12 Cel.) it does not reach down to that temperature. Then it could be either it's a sealed system problem( leaking refrigerant or under charge if it's a new unit). Or it could be a control problem( electronic control or sensor)
