Failure of Refrigeration
Failure of refrigeration does not necessarily indicate
that the cooling system is defective. Other factors
governing its operation must be checked.
governing its operation must be checked.
If the refrigerator is operating on gas and a loss of
cooling is noticed, switch the refrigerator to AC elec-
tric operation. (See "Operating Instructions on page
13). If the refrigerator has been operating on electric,
switch to gas operation.
tric operation. (See "Operating Instructions on page
13). 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 as-
sure the refrigerator is cycling properly. This will de-
termine if a component failure in the electric or gas
controls is causing the cooling fault. If no cooling is
evident after eight hours (overnight), you must con-
tact your dealer or a Nocold service center to deter-
mine the cause of failure.

Note: Do not attempt to operate the refrigerator

will not power the cooling unit to its full capabili-

NOTE 1: Both GAS and AC modes require a 12 volt DC control voltage; Therefore, unit cannot start without the 12 volt DC source.
NOTE 2: Without 120 volts AC connected, unit will automatically try to start up in GAS mode; If gas is not present (bottle could be
empty), unit will try to start, then lock out. ("CHECK" light)
NOTE 3: No gas supply to burner, unit will try to start, then lock out. ("CHECK" light)
