Troubleshooting - Dometic RM 2352 Installation And Operating Instructions Manual

It is important to keep the refrigerator area free
from combustible material, gasoline and other
flammable vapors or liquids.
NOTE: The following maintenance is required once or
twice a year, but should only be done by a qualified ser-
viceman who is familiar with LP gas systems and refrig-

back of the refrigerator) for gas leaks. The LP gas
supply must be turned on. Apply a non-corrosive
bubble solution to all LP gas connections.
The appearance of bubbles indicates a leak and
should be repaired immediately by a QUALIFIED
SERVICEMAN WHO IS FAMILIAR WITH GAS
SYSTEM AND REFRIGERATORS.
C The LP gas pressure should be checked and the
main regulator readjusted if pressure is incorrect.
The correct operating pressure is 11 inches of
water column. The correct place to take the LP gas
pressure is at the test port just ahead of the burner
jet. (See FIG. 11).
Inspect the flue baffle. It should be reasonably
clean and free of soot. Heavy soot formation
indicates improper functioning of the burner. The
flue and burner both require cleaning in the follow-
ing manner:
1. Unplug the refrigerator power cord from the
volt AC~outlet. (See FIG. 8).
2.
If the refrigerator is equipped for 12 volt DC.
Disconnect or shut off the 12 volt DC power to the
refrigerator.
3. Turn manual shutoff valve to OFF. (See FIG. 11).
4. Remove cover from the burner housing. (See fig.
5. Disconnect the wire from the high voltage elec-
trode.
6. Remove the burner mounting screw and remove
the burner assembly. (See FIG. 11).
7.
Lift out the wire and flue baffle from the top of flue
tube. Clean the flue from the top using a flue brush.
Blowing compressed air into the flue
properly clean soot and scale out of the flue tube.
Replace the flue baffle.
Clean burner tube with a brush. Blow out burner
with compressed air.
9.
Before removing burner jet, clean burner area of
soot and scale that fell out of flue tube. Remove the
burner jet. Soak the jet in wood alcohol and blow it
out with compressed air. Reinstall and tighten
burner jet.

DO NOT use a wire or pin when cleaning the burner
jet as damage can occur to the precision opening.
This can cause damage to the refrigerator or create
a fire hazard.
10. Reinstall burner, being careful that the end of the
burner fits into the slot on the burner bracket.
Check to make sure slots are centered under the
flue tube and the thermocouple is positioned
properly (tip of thermocouple extends
