OVERLOAD PROTECTOR LOCATION
3. Disconnect the black wire to the thermal overload
protector (4), the white and black or red wires to
the compressor.
4. With a voltmeter, check voltage across the black wire
removed from the thermal overload protector and
the white wire with 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” posi-
tion. Connect the dispenser to the power source.
The indication must be:
a) 120 volts ac for 120 volt models.
b) 230 volts ac for 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. Check for continuity across contacts 1 & 2 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, discon-
nect the black or red 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.
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.
Compressor Start Capacitor:
1. Check for continuity across the terminals on the
compressor start capacitor.
If continuity is present as described, the start capacitor
is operating properly.
If continuity is not present as described, replace the
capacitor.
Location:
The compressor assy is located inside the front
of the dispenser chassis.
1. Compressor Start Relay
2. Compressor Start Capacitor
3. Compressor Run Capacitor
4. Thermal Overload Protector
5. Overload Protector Retainer
6. Compressor Terminal Cover
7. Compressor Terminal Cover Retainer
Test Procedures:
Compressor Start Relay: Refer to FIG. 17
WARNING: The compressor capacitors must be prop-
erly discharged before proceeding.
1. Disconnect the dispenser from the power source.
2. Remove the compressor terminal cover retainer
(7) and compressor terminal cover (6).
