Test Procedures: 
WARNING: The compressor start capacitor must be 

properly discharged before proceeding.
Compressor Start Relay: Refer to FIG. 12

1.  Disconnect the dispenser from the power source.

2.  Remove  compressor  terminal  cover  retainer  (6) 

and compressor terminal cover (5).

3.  Disconnect the black wire from the thermal over-

load protector (3) and white/black wire from the 

compressor start relay (1).

4.  With a voltmeter, check voltage across the black 

wire  and  the  white/black  wire  and  the  ON/OFF 

switch in the “ON” position, DAY/NIGHT switch in 

the “DAY” position and the ICE/OFF/NO ICE switch 

in the “ICE” position. Connect the dispenser to the 

power source. The indication must be 120 volts ac 

for two wire 120 volt models or 230 volts ac for 

two wire 230 volt models.

5.  Disconnect the dispenser from the power source.

If voltage is present as described, proceed to #6.

If voltage is not present as described, refer to the Wiring 

Diagram and check the dispenser wiring harness.

6.  Disconnect the two black wires from the compres-

sor start capacitor.

7.  Remove relay from the compressor.

8.   Check for continuity across the upper left terminal 

and the right pin socket on the rear of the relay.

If continuity is present as described, the compressor 

start relay is operating properly.
If continuity is not present as described, replace re-

lay.
Compressor:

1.   With the compressor start relay (1) removed, dis-

connect the black wire from the compressor.

2.  Check  for  continuity  across  the  terminal  on  the 

compressor and the left pin on the compressor.

If continuity is present as described, the electrical part 

of the compressor is operating properly.
If continuity is not present as described, replace the 

compressor.
Thermal Overload Protector:

1.  Check for continuity across the terminals on the 

thermal overload protector (3).

If continuity is present as described, the thermal over-

load protector is operating properly.
If continuity is not present as described, replace the 

thermal overload protector.

Location:

The compressor assy is located inside the front 

of the dispenser chassis.
