Troubleshooting
If the refrigerator does not cool correctly:
- Make sure the thermostat knob is not in the 0 position.
- Make sure the compartment control is at the temperature setting that you wish.
- Make sure that the power source to the refrigerator is serviceable.
- Make sure that the fuse or circuit breaker is intact (See "Over current protection system")
- Make sure that the refrigerator is correctly installed and that the built in vents are not blocked.
- Make sure that the ambient temperature is not unusually high (more than 110° F. / 43° C.) (See "Over heating shut-off device
operation").
- Make sure that the doors are closed.
- Make sure that the door gaskets are sealing correctly.
- Make sure that the air circulation inside the refrigerator is not decreased by foods or by shelves that are covered with plastic, paper,
etc.
- Make sure that hot foods were not placed in the fresh food compartment of the refrigerator.
- Make sure that the freezer is defrosted.
After you make these checks, if the refrigerator does not operate, contact your dealer or an authorized Norcold Service Center.
Overheating shut-off device operation:
Operating the refrigerator in high ambient temperatures can overheat the compressor and cause premature failure of the compressor
(See the label inside the refrigerator).
To protect the compressor from overheating, 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:
The voltage required to start the refrigerator initially is 10.9 volts. 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 10.4 VDC
Restart 11.8 VDC
Overcurrent protection system:
Your refrigerator has an overcurrent 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 blue power light does not come on, check the fuse, which is located in-line with the DC
connector, and the polarity of the DC power supply. If the refrigerator still does not operate, another problem can exist in the power
module. Have an authorized Norcold Service Center check the refrigerator.
