High Pressure Switch has Shut Down the Unit

Every Wine Guardian unit has a manual reset high pressure switch in the refrigeration system.
This switch shuts the compressor and condenser down if the head pressure in the system is too
high. It is intended to protect the compressor. Restricted airflow through the condenser is the most
common reason for the pressure to become too high. This can be caused by dust covering the
filter or an obstruction blocking the airflow in the duct or grille.
Possible Cause
Head pressure in unit is too high because an
obstruction is restricting air flow
