3)  Start Relay 
 

A start relay’s function is to energize and de-energize the compressor’s start 
winding.  The coil of the current type relay is connected in series with the run 
winding. When current flows through the coil, a magnetic force is produced, 
pulling the relay plunger up. With the relay plunger up, it connect the start 
winding and the run winding at the same time and the compressor starts. As the 
compressor reaches its running speed, there is not enough current flowing 
through the relay coil to keep the plunger up (because of gravity), the start 
winding is disconnected. 
 

1.  Unplug the WINEMATE cooling unit or disconnect power.  
2.  Remove the terminal cover from the compressor. 
3.  Disconnect and remove the relay. 
4.  Set the ohmmeter scale to the lowest setting.  
5.  Make sure the relay with the letters “TOP” facing up. 
6.  Place and hold one ohmmeter probe in one terminal, then place the other 

ohmmeter probe into the other terminal. The ohmmeter shall show an 
open circuit. If not, the start relay is bad and needs replacing. 

7.  Turn the relay upside down. 
8.  Place and hold the ohmmeter probe in one terminal, and place the other 

ohmmeter probe in the other terminal. The ohmmeter shall show zero 
resistance. If not, the start relay is bad and needs replacing. 

9.  If the start relay is good, reinstall and reconnect the relay with the letters 

“TOP” facing up. 

 

4) Overload Protector 
 

The overload protector is a bi-metal that protects the compressor. If the 
compressor gets too hot the overload protector opens and stops the compressor. 
Once it has cooled the overload protector contacts close.  
 

1.  Unplug WINEMATE cooling unit or disconnect power.  
2.  Remove the terminal cover from the compressor. 
3.  Disconnect and remove the overload protector 
4.  Set the ohmmeter scale to the lowest setting.  
5.  Touch and hold one ohmmeter probe to one terminal on the overload 

protector, then touch and hold the other probe to the other terminal.  

6.  The ohmmeter shall show a reading of zero resistance. If not, the overload 

protector needs replacing. 

7.  Reinstall and reconnect the overload protector. 

 

5)  Temperature Controller 
 

The temperature controller allows the customer to select a temperature form 50 

°

F to 65 

°

F.  When the thermistor senses a temperature above the setting value,
