True beverage cooler is outside on our porch and has trouble holding a consistant temperature throughout the day. 36 degrees during the evening and up to 55 degrees during the day. Been in the same location for 3 years and just started having the problem.

Try disconnecting from the mains for 15 minutes or so in an attempt to reset it. Or it may have a control panel lock on it? Can you go up and down with temperatures? 38' is the ideal temperature for beer.

Sounds like it may be cycling off hard due to high discharge pressure. Make sure the condenser under the unit is clean and the fan motor is running. It shouldn't be running 60f. A lot of people make the mistake of checking temperature with an empty unit. Put a couple of gallons of water in the unit so that the temperature evens out. These units do NOT run based on air temperature but rather on inside coil temperature. That will swing wildly with no load in the unit.

Probably... OK I am going to fill you in on something here that almost no one knows. The True coolers all use a thermostat that reads the coil temperature and has no idea what the box air temperature might be. They are all pretty much the same but have a few different variations. For most beverage coolers though they are getting the coil down to around 13-15 degrees and then shut off and stay off until the coil gets back up to 38-40 degrees.This means that the air temperature can be anywhere from 23 to 50 degrees at any given moment but the product temperature is going to average out in the middle. If the box is full no problem the temperature swing will not be anything like this because the product will keep the temperature more stable. If the box is empty you will need to put SOMETHING in there to help stabilize the temperature before panicking. 3 or 4 gallons of water will do. Also if you want to sleep better at night put a thermometer in a glass of water in the cooler to get a better idea what your product temperature really is and don't put too much faith in the cheap dial thermometer mounted to the outside of the box. Oh and set the dial on 5 and if that doesn't work the thermostat could be a problem... they are the weak link in these units.

The purpose of a wine cooler is to store wines at their proper temperatures in a proper manner. Wine coolers are set to higher temperature ranges than other systems simply because wine should not be kept as cool as other beverages.

Thermostat Set @5, 36 Degrees F

If I am not mistaken, the True line-up of coolers have a temp control on them that is labeled 0-9.

This particular type of temp control is a coil temp control. I measures the temperature of the coil rather than air temperature.

Always set the control to the warmest setting and move it colder by one number at a time until your product reaches and holds designed temp. Do not go by cooler air temperature as there will be a great swing in temp especially if the doors are used frequently. Always temp the product. In the case of beer, your ideal holding temp is between 35-38°.


If you set the temp control to the warmest setting and the cooler is still freezing product, you will need to have the cooler serviced be a refrigeration tech. It will most likely be a bad control but there may be underlying problems.

Remove the doors, then the evaporator cover. Just be careful.

Brand new installed avanti beverage cooler. In a basement undercounter so room temp. around 65 degrees. Only gets to around 45 degrees inside even though temp is set to 34 degrees. Most of the time it sits for days without being opened but still not cold. Any suggestions on how to fix this problem?

Defective cold control thermostat

If you're handy with a soldering iron, it's possible to 'trick' the fridge into cooling down a few more degrees.

Long version:
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.

Short version:
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.
