230 VOLT (60/50Hz) POWER GRID SYSTEM
Symptom: Refrigerator does not cool or operate.
Remedy: Is the 230 V electrical plug in a 230 VAC outlet? If not, plug it in.
Is the 115V electrical plug connected to the 115 VAC outlet on the transformer.
Is the circuit breaker for the 230V outlet open? If so, reset the circuit breaker.
Is the thermostat dial turned to an operaonal posion (not OFF)? If not, start with a seng of
4 and turn to the seng you want. If the thermostat sll does not start the refrigerator, check
the thermostat for connuity: turn the dial fully counter-clockwise and check the resistance
between the two electrical connectors of the thermostat. It should be an open circuit. Turn
the dial clockwise unl you hear the click of the contacts inside. From this point on, resis-
tance between the connectors should be approximately zero ohms. If the thermostat checks
out bad, see par. 3-11 for replacement procedure.
If the system sll does not start, with a new thermostat if the old one failed the connuity test,
substute a new starter relay. Follow par. 3-7 through step g. Then remove the terminal
connectors from the relay terminals, pull the relay o the pins holding it to the compressor.
Install a new relay onto the compressor plug and reverse the procedure to connect the system
for running.
Symptom: Refrigerator operates, but does not cool.
Remedy: Has the refrigerator been turned on for at least an hour?
Is the thermostat set to a low enough temperature. If not, try a lower seng.
If the refrigerator sll does not cool open the door and touch the cold plate (evaporator). If the
cold plate has frost and is cold to the touch, see par. 3-11, for replacing the thermostat.
If the cold plate is warm, return the refrigerator to depot for further checks and/or replace-
ment.
Symptom: Arcles in the refrigerator and/or freezer secon are too warm.
Remedy: Has the refrigerator been turned on for at least an hour?
Is the thermostat set to a low enough temperature? If not , try a higher seng.
If the refrigerator sll does not cool, open the door and touch the cold plate (evaporator). If the
cold plate has frost and is cold to the touch, see par. 3-11, for replacing the thermostat.
If the cold plate is warm, return the refrigerator to depot for further checks and/or replace-
ment.
Symptom: Arcles in the refrigerator and freezer secon are too cold.
Remedy: Has the refrigerator been on for at least 1 hour?
Is the thermostat seng too high? If so, turn the dial to a lower seng, and let the refrigerator
run for at least two hours to check the temperature. If it is sll too cold, reduce seng to a
lower number.
If changing the thermostat seng does not warm the refrigerator, see par. 3-11, for replace-
ment of the thermostat.
3-6 Correcve Maintenance Procedure
CAUTION
Before performing any of the following, be sure that the
refrigerator is unplugged from its power source.
