HOT/COLD SWITCH (Optional)
Location:
The hot/cold switch is located on the left side
of the whipper motor mounting panel.
Test Procedure:
1. Disconnect the dispenser from the power source.
2. Disconnect the four pin plug from the hot/cold
switch and the four pin connector on the main
wiring harness.
3. Press the left dispense switch on the door and
check the voltage across the white wire (P4) and
red wire (P2) in the four pin connector on the main
wiring harness with a voltmeter. Connect the dis-
penser to the power source. The indication must
be:
a) 120 volts ac for two wire 120 volt models.
b) 120 volts ac for three wire 120/208 volt or 120/
240 volt models.
c) 240 volts ac for two wire 240 volt models.
4. Disconnect the dispenser from the power source.
If voltage is present as described, reconnect the four
pin plugs and proceed to #5.
If voltage is not present as described, refer to the
wiring diagram and check the main wiring harness.
5. Disconnect the wires from the switch termi-
nals.
6. With the switch in the upper “Cold” position check
for continuity between the center terminal and
the bottom terminal. With the switch in the down
“Hot” position check for continuity between the
center terminal and the upper terminal.
If continuity is present as described, the hot/cold
switch is operating properly.
If continuity is not present as described, replace the
switch.
Removal and Replacement:
1. Remove all wires from the switch terminals.
2. Remove the mounting nut on the front of the
whipper motor mounting panel.
3. Remove the hot/cold switch from the rear of the
front panel and discard.
4. Reconnect the wires to the terminals on the rear
of the new switch.
5. Push new hot/cold switch through the hole on
the left side of the whipper motor mounting panel
and secure with mounting nut.
6. Refer to Fig. 16 when reconnecting the wires.
