FIG. 27 HOT/COLD SWITCH |
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, with a voltmeter, check the voltage across the white wire (pin 4) and red wire (pin 2) in the four pin connector on the main wiring harness. Con- nect the dispenser to the power source. The indi- cation must be:
a)120 volts ac for two wire 120 volt models, and three wire 120/208 volt and 120/240 volt models.
b)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 Diagrams and check the main wiring harness.
5.Disconnect the wires from the switch terminals.
6.With the switch in the “Cold” (upper) position check for continuity between the center terminal and the bottom terminal. With the switch in the “Hot” (lower) position check for continuity be- tween 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 whip- per 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. 28 when reconnecting the wires.
