Read and understand the following maintenance sections of
this manual.
NOTE: Norcold is not responsible for installation, adjustment,
alteration, service, or maintenance performed by

authorized service center.
Have a qualified RV dealer or a Norcold authorized service
center do these annual safety and maintenance checks:
- Examine the gas supply lines for leaks.
- Replace or repair if needed.
- Make sure the propane gas pressure is 11 inches of water
column.
- Adjust if needed.
- Make sure the combustion seal is complete and intact.
- Replace or repair it if needed.
- Make sure the burner and the burner orifice are clean.
- Clean if needed.
- Make sure the electrode spark gap is 1/8 - 3/16 inch.
- Adjust if needed.
- Make sure the AC voltage is 108 - 132 volts and the DC
voltage is 10.5 - 15.4 volts.
- Make sure the thermocouple tip is clean and secure.
- Make sure the area at the rear of the refrigerator is free of
any combustible materials, gasoline, and other flammable
vapors and liquids.
Check the seal of the doors.
If either door does not seal correctly, excess frost will collect
inside the refrigerator. Make sure the doors seal correctly (See
Art00980):
- Close each door on a piece of paper that is about the size
and thickness of a dollar bill.
- Gently pull the paper.
- You should feel a slight drag between the gasket and
the cabinet.
- Do this on all four sides of the door.
- If you do not feel a slight drag on the
paper, the door does not seal correctly.
- Have your dealer or an authorized Norcold Service
Center correct the seal of the door.
