Connect the dispenser to the power supply. 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. 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. With a voltmeter, check the voltage across the remaining two wires of the dispense switch being tested from the door interconnect wiring harness. Connect the dispenser to the power source. The indication must be +5 volts dc. If voltage is present as described, proceed to #7. If voltage is not present as described, refer to the wiring diagram and check the dispenser wiring harness. DISPENSE SWITCH(S) - FMD-4 & FMD-5 FIG.13 DISPENSE SWITCHES P2636 Location: The dispense switches are located on the lower outside of the dispenser door. FMD-4 FMD-5 SERVICE (cont.) 35135 012103 SERVICE (cont.) DISPENSE SWITCHES (cont.) 7. Check for continuity across the terminals (top right to top left; bottom right to bottom left) of the dispense switch with the switch in the “ON” position. Continuity must not present when the switch is in the “OFF” released position. If continuity is present as described, reconnect the connector to the door interconnect wiring harness, the switch is operating properly. If continuity is not present as described, replace the switch. Removal and Replacement 1. Open the dispenser door. 2. Remove the six #8-32 screws securing the bottom door cover and remove cover. 3. Disconnect the wires on the dispense switch from the door interconnect wiring harness. 4. Compress the clips inside the door on the dispense switch and gently push the switch through the opening 5. Push the new switch into the opening and spread the clips to hold the switch in the door. 6. Reconnect the wires to the dispense switch from the door interconnect wiring harness. 7. Reinstall the door bottom cover using six #8-32 screws. 8. Refer to Fig. 14 when reconnecting wires.

FAN FIG. 15 FAN Location: The fan is located inside the dispenser housing on the center rear of the dispenser base plate. Test Procedures: 1. Disconnect the dispenser from the power source. 2. Disconnect the black and white wires from the fan terminals. 3. Check the voltage across the black and white wires on the main harness with a voltmeter. Connect the dispenser to the power source. The indication must be: a) 120 volts ac for two wire 120 volts models. b) 120 volts ac for three wire 120/208 volt or 120/ 240 volt models. If voltage is present as described, replace the fan If voltage is not present as described, refer to wiring diagram and check the dispenser wiring harness. Removal and Replacement: 1. Disconnect the vacuum hose from the fan. 2. Remove the two #8-32 locking screws securing the fan to the dispenser housing base plate. 3. Disconnect the wires from the fan terminals and discard the fan 4. Refer to Fig. 16 and connect the wires to the new fan. 5. Install new fan through the rear access hole and secure to the dispenser housing base plate using two #8-32 locking screws. 6. Reconnect the vacuum hose to the fan.

FROTHER AND WHIPPER MOTOR - FMD-4 (shown) & FMD-5 FIG. 17 FROTHER AND WHIPPER MOTOR Location: The frothers are located behind the dispenser door, mounted on the front panel inside the whipper chamber. The whipper motors are located on the back side of the whipper motor mounting panel. Test Procedure: 1. Disconnect the dispenser from the power source. 2. Disconnect the red and white wires (FMD-1 & FMD-2 left motor) or orange and white wires (FMD-2 right motor) of the main harness from the black leads of the motor. 3. Press and hold the dispense switch and check the voltage across the disconnected harness wires with a voltmeter. Connect the dispenser to the power source. The reading 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. 4. Disconnect the dispenser from the power source. If voltage is present as described, replace the motor. If voltage is not present as described, refer to the wiring diagrams and check the dispenser wiring harness.
