Read and understand the following maintenance sections of this
manual.
NOTE: Thetford is not responsible for installation,
adjustment, alteration, service, or maintenance
performed by anyone other than a qualified RV
dealer or an authorized Thetford Service Center.
Have a qualified RV dealer or an authorized Thetford Service
Center do these annual safety and maintenance checks:
- Examine the gas supply lines for leaks.
- Replace or repair if necessary.
- Make sure the propane gas pressure is 2.7 kPa.
- Adjust if necessary.
- Make sure the combustion seal is complete and intact.

Refrigerator Storage
Before the refrigerator is stored for an extended (seasonal)
period of time:
- Defrost and clean the interior of the refrigerator.
- Close the doors with the storage latch.
If the refrigerator is stored for an extended period of time, before
start up:
- Make sure there are no obstructions in the vents, the
ventilation air pathway, the burner, the orifice, or the flue
area.
Door Sealing
If the door does not seal correctly, excess frost will collect inside
the refrigerator. Make sure the door seals correctly:
- Close the door on a piece of paper that is about the size and
thickness of a dollar bill (See Art00980).
- 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 is not sealing correctly:
- Make sure the screws of the hinges are tight.
- Make sure the door gasket does not touch the door
latch:
- If the door gasket touches the door latch,
loosen the screws of the door latch.
- Raise the door latch just so it does not touch
and tighten the screws of the door latch.
- Make sure the door latch holds the door closed
- Make sure the burner and the burner orifice are clean (See
Art00956).
- Clean if necessary.
- Make sure the electrode spark gap [3] is 3-5 mm (See
Art00955).
- Adjust if necessary.
- Make sure the AC voltage is 216 - 252 volts and the DC
voltage is 11.7 - 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.
