Thermistor Tests: This test will give a “GO – NO GO” test of all thermistors. Pressing the Power Interrupt Button will report the

condition of the thermistor. Note: The condition displays that follow apply to the tests for all thermistors.

Service Test 03 – Fresh Food Thermistor

PA=Pass; oP=Open; Sh=Shorted

Service Test 04 – Freezer Thermistor

PA=Pass; oP=Open; Sh=Shorted

Service Test 05 – Evaporator Thermistor

PA=Pass; oP=Open; Sh=Shorted

Service Test 06 – Ambient Thermistor

PA=Pass; oP=Open; Sh=Shorted

Fan Tests: This test will give a “GO – NO GO” test of the Fresh Food and Evaporator Stirrer fans. Pressing the Power Interrupt

Button will result in one of the following displays. The fan will always initially display Lo for fan too slow. Let the fan spin up to

speed for accurate test. This will only take a few seconds.

Service Test 07 – Fresh Food Fan

PA=Pass; Lo= Fan running too slow; Hi= Fan running too fast

Service Test 08 – Evaporator / Freezer Fan Test

PA=Pass; Lo= Fan running too slow; Hi= Fan running too fast

Service Test 09 – Open Damper Fresh Food Compartment

Tap the Power Interrupt Button and the damper will move to the open position. There is no change in the display while the damper

opens. It takes between 7 and 15 seconds for the damper to move to the open position.

Service Test 10 – Close Damper Fresh Food Compartment

Tap the Power Interrupt Button and the damper will move to the closed position. There is no change in the display while the

damper closes. It takes between 7 and 15 seconds for the damper to move to the closed position.

Service Test 11 – Defrost Heaters

If the defrost safety thermostat is closed the defrost system will draw approximately 3 amps. Pressing the Power Interrupt Button

while at Service Test 11 will energize the defrost heaters. When the Power Interrupt Button is tapped the display will indicate the

current evaporator temperature on the fresh food side of the display. The temperature should begin to quickly rise when the

heaters are energized. This can be used to quickly determine if the defrost system is energized.

Service Test 12 – Condenser Fan

This test will energize the condenser fan. Pressing the Power Interrupt Button will activate the test. Line voltage should be present

at JP13 pin 1.

Service Test 13 – Fresh Food Lights

This test will energize the fresh food lamps. Pressing the Power Interrupt Button will energize the fresh food light system. Line

voltage should be present at JP12 pin 2.

Service Test 14 – Freezer Lights

This test will energize the freezer lamps. Pressing the Power Interrupt Button will energize the freezer light system. Line voltage

should be present at JP 12 pin 3.

Service Test 15 – Fountain Lamp

This test will energize the fountain lamp (dispenser light). Pressing the Power Interrupt Button will energize the fountain lamp. Line

voltage should be present at JP8 pin 9.

Service Test 16 – Compressor Maximum Speed

The compressor should have been off for at least five minutes prior to this test. If the off time is not five minutes, the short cycle

protection within the compressor controller will prevent operation until enough time has elapsed. The Service Test may time out

(three minutes) before sufficient time has elapsed for the compressor to start. If the display changes back to this display (16 00)

reactivate the test. Pressing the Power Interrupt Button will start the compressor at maximum speed. The display will show the

current evaporator temperature on the fresh food side of the display. If the compressor is working, this temperature should quickly

drop. If the compressor does not eventually start after waiting for at least five minutes check for the following conditions: JP10,

pins 1 to 2, 2-2.5VAC this is the drive signal from the Main Control Board to the Compressor Controller. CN 05 pins 1 to 6,

230VAC, this is the output from the compressor controller to the compressor.
