Screen No. 4 - AC Electric Input Volt-
age
This screen displays AC input voltage measured by
control.
A - Identifies information screen.
B -The control will display the AC input volt-
age to refrigerator. Each LED is assigned a
number. To determine AC input voltage, add
numbers above illuminated LED for voltage.
Shown: 64+32+16+8=120 VAC
To verify:
1 - Measure input voltage at receptacle supply-
ing AC voltage to refrigerator. Voltage should
be +/- 10 VAC of control display.
2 - Measure output voltage of the control board
to AC heater. Voltage should equal input volt-
age measured in Step 1.
Screen No. 5 - AC Heater Current
This screen displays AC current measured by the
control (decimal point implied).
A - Identifies information screen.
B - The control will display the AC heater
current measured by control. Each LED is as-
signed a number. To determine current of AC
heater, add numbers above illuminated LED.
Shown: 16+8+4+1=29 or 2.9 amps
(decimal point implied)
To verify:
1 - Measure AC current draw through AC
heater (2.7-2.9 amps). The current will be +/-
10% of the control display.
