Summary

Description of Alphanumeric Codes for 900 Series (Diagnostic Indicators)

A1-LP Gas Ignition Failure

Describes the A1 code for burner ignition failure during initial start-up or re-ignition.

A2-LP Gas Re-Ignition Failure

Details the A2 code for failure to re-ignite the gas burner during normal operation.

A3-Fresh Food Compartment Door Ajar

Explains the A3 code indicating the fresh food compartment door has been left open too long.

A4-AC Mode Selected, AC Power Not Available

Covers the A4 code when AC mode is selected but AC power is not available.

A5-AC Input Voltage Too Low

Describes the A5 code for low AC input voltage, leading to source switching or operation cessation.

A6-AC Input Voltage Too High

Details the A6 code for high AC input voltage, causing source switching or operation cessation.

A7-DC Input Voltage Too Low

Explains the A7 code for low DC input voltage, resulting in lockout of LP Gas and DC heater operation.

A8-DC Input Voltage Too High

C1-Burner Failed Ignition and DC Heater Failed

Describes the C1 code for burner ignition and DC heater failure in 3-Way AUTO mode.

C2-AC Heater Output Fault

Details the C2 code for AC heater output fault when the heater should be OFF.

C3-DC Heater Output Fault

Explains the C3 code for DC heater output fault in 3-Way models.

C4-DC Heater Failed Open

Covers the C4 code for DC heater failure (open circuit) where voltage is supplied but no current flows.

C5-Back-Up Operating System

Describes the C5 code indicating the Back-Up Operating System is active due to thermistor failure.

C6-AC Heater Failed Open

Details the C6 code for AC heater failure (open circuit) where voltage is supplied but no current flows.

C7-Flame Sense Circuit Failure

Explains the C7 code for a failure in the flame sense circuit.

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

Covers the C8 code for AC heater current being out of tolerance.

C9-DC Heater Failed for Current-Out-Tolerance

Details the C9 code for DC heater current being out of tolerance in 3-Way models.

d1-Inter Control Failure

Explains the d1 code indicating an internal control board failure.
