ELECTRONIC CONTROL FEATURES

The user interface in this appliance controls the product cooling system. The product cooling diagnostics is in the bag of this page. temperatures in the refrigerator The cooling portion of the electronic control in this appliance controls the compartment and pulses the defrost heater.

The pulsed defrost feature is controlled in the following manner:

1. Pulsed Defrost Heat – During the defrost cycle the heater is energized continuously for the first 5 minutes. It is then cycled off for 180 seconds and on for 120 seconds. This on/off cycle is repeated until

the Refrigerator thermistor reach the cut-in temperature or the maximum defrost time ( 55 minutes ) is reached.

To ENTER DIAGNOSTICS MODE:

Set Freezer Temp to lowest setting prior to entering SERVICE DIAGNOSTIC MODE. (LED 1 should be only LED

illuminated over “Freezer Temp”)

Press SW6 and SW4 simultaneously for at least 3 seconds.

Release both buttons after all LED’s are illuminated for 1 second.

All Icons and loads are turned Off. The Service Personal must use SW1 button

to advance steps into Service Mode.

The display will show LED1 on to indicate the control is in step 1 of the diagnostics routine.

Each step must be manually advanced. Press SW1 to move to the next step in the sequence.

Diagnostics will begin at Step 1 following the sequence shown in Table 1. To guarantee good voltage

comparison to indicate load failure, a minimum of 2 seconds is needed in each step for system stabilization.

All thermistors will be tested without action required from Service Technician. This check is done after

Heater Off (Step 6).

To EXIT SERVICE DIAGNOSTICS Mode, do one of the following 4 options: operation. 1) Press SW1 and SW2 simultaneously for 3 seconds. 2) Disconnect the product from power. 3) Allow 20 minutes to pass. 4) Press SW1 after service check completed. Following the exit of the diagnostic mode, the controls will then resume normal

PASS CONDITION: Pressing SW1 while in Step 13 the system returns to normal mode. FAIL CONDITION: Pressing SW1 while in Step 13 fail message status is displayed by blinking LED´s for specific failure as shown in Table 2.
