Digital Controller - Vinotemp WINE-MATE VINO3500HZD Service Manual

The overload protector is a bi-metal that protects the compressor. If the
compressor gets too hot the overload protector opens and stops the compressor.
Once it has cooled the overload protector contacts close.
1. Unplug WINEMATE cooling unit or disconnect power.
2. Remove the terminal cover from the compressor.
3. Disconnect and remove the overload protector
4. Set the ohmmeter scale to the lowest setting.
5. Touch and hold one ohmmeter probe to one terminal on the overload
protector, then touch and hold the other probe to the other terminal.
6. The ohmmeter shall show a reading of zero resistance. If not, the overload
protector needs replacing.
7. Reinstall and reconnect the overload protector.

5) Digital Controller

The digital controller allows the customer to select a temperature form 50 °F to
65 °F. When the thermistor senses a temperature above the setting value, the
digital controller will turn on the compressor and fan motors. Once the selected
temperature is sensed, the controller will turn off the cooling unit.
A. Resistance
