Thetford Norcold 9183 - Manual (Page 13)

Failure of refrigeration does not necessarily mean the cooling system is defective. Check other factors governing
its operation.
If a diagnostic indicator appears, see Diagnostics.
If the refrigerator is operating on gas and a loss of cooling is noticed, switch the refrigerator to AC mode of
operation (see Start-Up Instructions).
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
