Resetting the High-Pressure Switch 

 

1.  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 until it locks into position. 

 

4.  Push the rocker switch to restart the unit. 

 

 
 
 
 
 
 

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 

Solution 

Head Pressure in unit is too high because 
an obstruction is restricting airflow 

Remove the obstruction in the duct/grille 
or clean the filter. Then restart the unit 
after resetting the high-pressure switch.
