Basic Refrigeration Troubleshooting

In this refrigeration tutorial video, Vendnet demonstrates some basic troubleshooting methods to diagnose and fix a refrigeration unit that is not cooling properly. You will learn how to troubleshoot the refrigeration system by monitoring the temperature and how to spot concerns with temperature sensors and settings. These steps are simple to perform and can be helpful to cool the machine again so you can serve sandwiches, salads, drinks and other cold items.

Examining the air filter and replacing it with a new one is the first step in refrigeration unit maintenance. We recommend replacing your air filter every three months. Check the evaporator coil and fan for frosting. By placing the machine in service mode, you can check the condition of the fan and compressor. It’s also imperative you keep the machine four inches away from the wall to allow for free air flow circulation. If the machine is still not cooling, ensure the cold food and temperature settings are correct.
