Summary

Safety Information

Operating Controls

Operating Sequence-900 and 9100 Series

Auto Mode

Describes automatic energy source selection based on priority and availability.

Manual Mode

Explains manual mode selection and consequences of interrupted energy sources.

LP GAS Mode Operation

Details the ignition cycle, lockout, and re-ignition attempts for LP Gas operation.

Description of Alphanumeric Codes for 900 Series (Diagnostic Indicators)

A1-LP Gas Ignition Failure

Covers burner ignition failure on initial start-up or during normal gas operation.

A2-LP Gas Re-Ignition Failure

Describes LP gas re-ignition failures during normal gas operation cycles.

A5-AC Input Voltage Too Low

Signifies low AC input voltage affecting refrigerator operation and energy source selection.

A6-AC Input Voltage Too High

Indicates high AC input voltage that may cause operational issues or shutdowns.

A7-DC Input Voltage Too Low

Alerts to low DC input voltage, potentially locking out LP Gas or DC heater operation.

A8-DC Input Voltage Too High

Signals high DC input voltage, which might require correction for proper operation.

C1-Burner Failed Ignition and DC Heater Failed

Indicates failure in burner ignition and DC heater for 3-way models in AUTO mode.

C2-AC Heater Output Fault

Detects AC heater current when the AC heater should be OFF, causing operation lockout.

C3-DC Heater Output Fault (3-Way Models Only)

Senses DC heater current when the DC heater should be OFF in 3-way models.

C4-DC Heater Failed Open (3-Way Models Only)

Indicates DC heater is supplied voltage but not drawing current, resulting in no cooling.

C6-AC Heater Failed Open

Occurs when AC heater receives voltage but doesn't draw current, affecting operation.

C7-Flame Sense Circuit Failure

Indicates a problem with the circuit that senses the burner flame for ignition.

C8-AC Heater Failed for Current Out-of-Tolerance

Detects AC heater current outside specified tolerance, impacting operation.

C9-DC Heater Failed for Current-Out-Tolerance (3-Way Models)

Signals DC heater current outside specified tolerance for 3-way models.

d1-Inter Control Failure

Indicates a malfunction within the refrigerator's main control board.

Description of 9100 Series Flashing LED's (Diagnostic Indicators)

Flashing LP Gas LED - Burner Ignition Failure

Indicates burner ignition failure on initial start-up or during normal operation.

Flashing AC LED - AC Input Voltage Out of Range

Indicates AC input voltage is either too high or too low for proper operation.

Flashing Battery LED - DC Input Voltage Out of Range

Signals that the DC input voltage is either too high or too low.

All LEDs Flashing (3-Way) - Burner Ignition & DC Heater Failure

In AUTO mode, indicates burner failed ignition and DC heater for 3-way models.

All LEDs Flashing (All Models) - AC Heater Output Fault

The control senses AC heater current when the AC heater should be OFF.

All LEDs Flashing (3-Way) - DC Heater Output Fault

The control senses DC heater current when the DC heater should be OFF.

All LEDs Flashing (3-Way) - DC Heater Failed Open

DC heater is supplied voltage but not drawing current, resulting in no cooling.

All LEDs Flashing (All Models) - AC Heater Failed Open

AC voltage supplied to heater, but AC heater not drawing current.

All LEDs Flashing (All Models) - Flame Sense Circuit Failure

Indicates a problem with the circuit that senses the burner flame.

All LEDs Flashing (All Models) - AC Heater Current Out of Tolerance

AC heater current deviates from the acceptable operational range.

All LEDs Flashing (3-Way) - DC Heater Current Out of Tolerance

DC heater current deviates from the acceptable operational range for 3-way models.
