High Pressure Switch has Shut the Unit Down
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 Solution
Head Pressure in unit is too high because Remove the obstruction in the duct or grille or
an obstruction is restricting air flow clean the filter. Then restart the unit after
resetting the using the high pressure switch.
Instructions to Reset High Pressure Switch

 Locate the high pressure switch near the compressor (a cylindrical device piped into the
refrigeration system with two wires a red button on the top).
