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
Head Pressure in unit is too high because
an obstruction is restricting air flow
Solution
Replace bulb
Solution
Clean trap
Remove blockage and clean
Level with shims
Solution
Redirect airflow
Add baffles
Add insulated ductwork
Add sound baffle between unit and occupied
space
Solution
Remove the obstruction in the duct or grille or
clean the filter. Then restart the unit after
resetting the using the high pressure switch.
