Trouble Shooting
If the refrigerator does not cool properly:
- Ensure the power switch/thermostat is not in the off position
- Ensure the power switch/thermostat is at the temperature setting that you wish
- Ensure the power source to the refrigerator is serviceable
- Ensure the fuse or circuit breaker is intact (see "Over Current Protection System")
- Ensure the refrigerator is correctly installed and that the built in vents are not blocked
- Ensure the ambient temperature is not unusually high(more than 110° F/43° C)
- Ensure the door is closed
- If the weather is hot, ensure the door is sealing correctly
- Ensure the air circulation inside the refrigerator is not decreased by foods or covered shelves
- Ensure hot foods were not placed in the fresh food compartment of the refrigerator
- Ensure the freezer is defrosted
After you make these checks, if the refrigerator does not operate, contact your dealer or an authorized
Norcold Service Center.
Over-Heating Shut-Off Device Operation
Operating the refrigerator in high ambient temperatures can over heat the cooling unit and cause
premature failure of the compressor (see the label inside the refrigerator).
To protect the cooling unit from over heating, the refrigerator will automatically shut off when the
temperature of the power module is higher than 212° F (100° C). The refrigerator will not restart until
the temperature of the power module is lower than 176° F (80° C).
Low Voltage Protection System
In order to prevent completely draining the battery, the refrigerator will automatically shut-off when
the DC supply voltage becomes too low. The refrigerator will not restart until the DC supply voltages
increases. These shut-off and restart voltage levels are:
12VDC Operation
Shut-off 10.4VDC
Restart
11.6VDC
If the DC supply voltage is outside of the listed limits above, the refrigerator will not operate.
Over-Current Protection System
Your refrigerator has an over-current protection system in the electronic circuit to prevent damage
to the inverter, which may occur due to a reverse polarity connection.
If the refrigerator does not operate and the green power light does not come on, check the fuse
located in line with the DC connector and the polarity of the DC power supply. If the refrigerator
still does not operate, another problem may exist in the power module. Have an authorized Norcold
Service Center inspect the refrigerator.
24 VDC Operation
Shut-off 22.7VDC
Restart
24.0VDC
