SECTION 10 Error Codes
The codes are displayed ashing (alternating between
temperature and message) on the display.
No communication between display and power modules.
The control system will revert to full automatic operation
selecting the best energy source available with AC rst
and GAS being second priority. The temperature setting
will be maintained at the mid position. The power module
will continually attempt to reestablish operation of the dis-
play module. Test control cable between upper and lower
control, control (on-off) panel and lower board, clean all
grounds, and try a different DC power source. If prob-
lem still exists change lower control board.
E 0
E 1
Hardware fault in the gas operation system. Test Up-
per and lower controls, solenoid, wire harness, clean all
grounds and try a different DC power source. If problem
still exist change lower control board.
A failure of the temperature sensor device or associated
electronic circuitry has occurred. If the connection to the
temperature sensor is faulty or the circuit to the thermis-
tor is open. The cooling unit will shut down to keep from
freezing the water tank in the refrigerator. Test Thermistor.
There has been a rare occasion where the lower control
board will not detect the thermistor.
SECTION 11 Diagnostic Mode
To perform a diagnostic test:
1. Turn off the refrigerator. (press ON/OFF button)
2. Press and hold the TEMP. SET button and then,
press the ON/OFF button.
3. Release the TEMP. SET button. Press it again to
toggle the list of functions step by step.

11.1 Diagnostic Test
Error Code Tips.
The DC line to the refrigerator should be a dedicated line.
Other components on the DC line could cause the voltage
to vary. Changes in voltage could/will/may create an error
code. It is possible for ame failure to occur even on AC
operation. When on AC operation the ame failure safety
checks are running constant. It does not mean the unit is
not operating on AC; just the unit has detected a problem
or glitch and shut down the gas side. Turning the unit off
and back on should eliminate the gas failure.
