FIG. 30 FAN

P1342

Location:

The fan is located inside the dispenser chassis just 

in front of the condenser.
Test Procedures:

1.  Disconnect the dispenser from the power source.

2.  Disconnect the yellow and white/black wires from 

the main harness to the fan leads.

3.  With a voltmeter, check the voltage across the yellow 

and the white/black wires and the “ON/OFF” switch 

in the “ON” position. 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.

4.  Disconnect the dispenser from the power source.

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 (Refer to Fig. 31)
NOTE: Leave the hopper in place. This keeps it in align-

ment while the condenser shroud is removed.

1.  Disconnect  the  fan  leads  from  the  wiring  har-

ness.

2.  Remove the four #6 crimptite screws securing the 

condenser shroud and fan assy (1) to the condenser 

and  the  two  #8-32  locking  screws  securing  the 

condenser shroud and fan assy (1) to the chassis 

base. 

3.  Remove the condenser shroud and fan assy from 

the right side of the dispenser.

4.  Remove the three #6 thread cutting screws securing 

the fan assy to condenser shroud (7). Set condenser 

shroud and screws aside for reassembly.

5.  Remove  the  three  #8-32  thread  forming  screws 

securing motor (5) to condenser fan shroud/mount 

(6). Set shroud and screws aside for reassembly.
