Piezo
Does the refrigerator not operate in gas
mode?
1. Depress the piezo button several times in
quick succession.
2. If you do not hear a click or do not
feel resistance each time the button is
depressed, replace the piezo.
Switch (AC or DC)
Does the refrigerator not operate in AC or
DC mode?
Confirm that the switch for the AC or DC
power is set to the on position.
Confirm that the voltage supplied to the AC or
DC switch is within specification.
Perform a diagnosis on the heating element.
If the problem persists, replace the switch.
Thermocouple
Does the refrigerator not operate in gas
mode?
Clean the thermocouple tip with an
alcohol- based solvent and let air dry.
1. Confirm that the gas is lighting but not
staying lit.
2. Confirm that the voltage of the
thermocouple while in the burner flame is
between 14–30 mV.
3. If the voltage is out of specification,
replace the thermocouple.
Thermostat
Does the refrigerator not get cold
enough in AC mode but does in DC or
gas mode?
Does the fresh food compartment freeze?
Does frost build up rapidly?
Adjust the thermostat to the appropriate
setting for the operating conditions.
I
If the ambient temperature is above 80 °F
(27 °C), or the door of the refrigerator is
opened frequently, the thermostat should
be set to 7.
1. Set the refrigerator to AC operation.
2. Set the thermostat to 5.
3. Place a bottle of water in the
compartment of the refrigerator.
4. When the thermostat turns off the heating
element, use a substance thermometer
to test the temperature of the water in the
bottle.
The temperature should read
approximately 40 °F (4 °C).
5. If the reading is out of specification,
replace the thermostat.
