Refrigerator Failure
Failure of refrigeration does not necessarily indicate that the cooling system is defective. Other factors governing its
operation must be checked.
If a diagnostic code appears, refer to "Diagnostic Codes and Their Meanings" on page 10. If the refrigerator is operating on
gas and a loss of cooling is noticed, switch the refrigerator to the AC mode of operation (see Start-Up Instructions on pages
8 and 9). If the refrigerator has been operating on electric, switch to gas operation. After the refrigerator has been switched
from one power source to the other allow several hours to assure the refrigerator is cycling properly. This will determine if a
component failure in the electric or gas controls is causing the cooling fault. If no cooling is evident after eight hours (or
overnight), the cause of failure may be the cooling unit. To determine the actual cause for failure, contact your dealer or a
Norcold service center.
Maintenance Requirements
1. Leak test gas supply piping and fittings at least once a year. This procedure should only be performed by your dealer or a
Norcold service center. These facilities are familiar with gas refrigerators and propane gas systems.
2. Check the main line gas pressure and adjust if necessary. The correct gas pressure is 11 inches water column. It is
recommended that your dealer or a Norcold service center perform this task.
3. Clean the refrigerator’s burner and burner orifice. This procedure is required once a year minimum and should
only be performed by your dealer or a Norcold service center.
4. Insure that the LP gas supply is Propane, not another fuel such as Butane or Butane mixtures. Question the facility in
which you purchase your gas.
5. Check the burner flame appearance during gas operation. Inspect burner electrode assembly to insure it is secure to burner bracket.
