Resetting the High-Pressure Switch

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 airflow
1. Shut off the unit at the power switch, Remove the access panel, grille, or duct
collar on the condenser to gain access to the High-Pressure Switch.
2. Locate the High-Pressure Switch near the compressor (Fig. 1).
3. Push the button to reset the High-Pressure Switch.
4. Push the power switch to restart the unit.
