TORQUE SENSOR CIRCUIT BOARD
FIG. 63 TORQUE SENSOR CIRCUIT BOARD P1341 |
Location:
The torque sensor circuit board is located on the rear of the cooling drum mount just left of center.
Test Procedures:
1.Place black meter lead at
DO NOT TURN ON AUGERS!
2.Using a strip of paper, momentarily block the light path between red LED and white phototransistor. If the meter displays 5vdc when blocked and 0v when unblocked, then the Torque Sensor is good. If there is no 5vdc reading, verify that both red and white sensors are clean.
3.If there is still no 5vdc reading when blocked, place the red meter lead at

Removal and Replacement:
1.Remove the two
2.Remove the cover and set aside for reassembly.
3.Remove the #8 locking screw on the lower right side of the auger motor mounting bracket securing the auger motor run capacitor. Set capacitor aside with wires attached.
4.Disconnect the auger motor plug from the connector on the main wiring harness.
5.Remove the three remaining #8 locking screws securing the auger motor mounting bracket to cooling drum mounting bracket.
6.Remove motor with mounting bracket, split pin/
torsion spring bearings as an assembly and set aside for reassembly.
NOTE: When removing or installing the motor be sure the split pin in the motor shaft is turned to a position that will clear the torque sensor circuit board.
7.Disconnect the plug from the dispenser main wiring harness to the torque sensor circuit board.
8.Remove the
9.Remove torque sensor circuit board and discard.
10.Install new torque sensor circuit board in the slot in the rear of the cooling drum mount and secure with a
11.Refer to Fig. 42 and reconnect the wires.
12.Reinstall motor with mounting bracket, drip tray, split pin and torsion spring bearings using three #8 locking screws onto the cooling drum bracket.
13.Install the auger motor capacitor on the lower right side of the auger mounting bracket using the remaining #8 locking screw.
14.Connect the auger motor terminal to the terminal on the main wiring harness.
15.Refer to Fig. 64 when reconnecting the wires.
16.Position the auger motor cover on the cooling drum mount and secure with two
