Unplugging your commercial fridge can act as a reset, which can be helpful if the problems are electronic or related to the control panel. After unplugging, wait a few minutes before plugging it back in. This process can reset the unit's control system, potentially resolving minor electronic glitches. Unfortunately, this method is unlikely to fix mechanical issues or problems related to component failures - such as a faulty compressor or refrigerant leak. If the refrigerator does not start cooling after being reset, get in touch with a professional to further diagnose the problem.
