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.
