2. CONTROLLER BOARD

Note: Refer to the controller board service manual.

IMPORTANT

If receiving a service call, ask the user to turn off the power to the icemaker and turn it on again, while watching the icemaker. This will reset the controller, and in some cases normal operation will resume.

CAUTION

1.Check that the icemaker has been earthed properly. If not, the controller board will not work properly.

2.Do not change wiring and connections, or the controller board will not work properly.

3.Do not touch the reverse side of the controller board and tiny electronic devices on it.

4.Do not repair the electronic devices and parts on the controller board in the field (except for fuse replacement). Replace the whole board assembly when it fails.

5.To get static free, always touch the metal part of the icemaker before servicing. Electrostatic discharge will cause severe damage to the controller board.

6.The signal ground wire must be connected to the control box when replacing the controller board after service.

7.The controller board is fragile. Handle with care. * Do not drop the board on the floor.

*Make sure that the board is placed correctly into the guides in the control box. Mis-alignment could cause breakage when replacing the control box cover.

*Handle the board by the edges only. Do not touch the electric parts and devices.

Procedure

Normal

 

 

 

 

 

 

 

1. Thermistor

 

 

CAUTION

 

 

5 -7 kilohms

 

 

 

 

(on evaporator)

 

Thermistor sensor part is fragile,

 

 

 

 

glass sealed. Handle with care.

 

 

 

 

 

 

 

 

 

 

* Disconnect the connector CN13 on

 

 

 

the board.

 

 

* Remove the screw and the

 

 

 

thermistor holder on the evaporator.

 

 

* Immerse the sensor part in a glass

 

 

 

containing ice and water for 5

 

 

 

minutes.

 

 

* Check the resistance between CN13

 

 

 

connector pins.

 

 

* Replace the thermistor in its correct

 

 

 

position.

 

 

* Connect CN13.

 

 

 

 

 

 

 

 

2. Bin Control Switch

Manually set the micro switch in the

Approx.

 

TRIP and RESET positions, and

TRIP(Closed) 10 sec.

 

check the period.

RESET(Open) 80 sec.
