NOTE: It will take a very
precise ohm meter to accu-
rately read this measure-
ment. If a precise ohm
meter is not available, a
continuity reading will
indicate an open or com-
plete circuit. If an open
circuit is the test result,
replace the element.

THERMOSTAT
(RM2201)
The thermostat regulates the cabinet temperature by
making and breaking the heat source circuit. The
internal mechanism breaks contact (continuity) when
adequate cabinet temperature has been reached.
Check the thermostat for continuity or use a jumper wire
with insulated clips and bypass the thermostat.
NOTE: Care should be used. Do not short to thermostat
casing. Also, remove the jumper after testing is com-
pleted.
If the above test allows the refrigerator to operate,
replace the thermostat.
SECTION 6
LP GAS REQUIRE-
MENTS
The LP gas pressure to the refrig-
erator should be
11
inches water
column with half of all BTU’s of the
RV turned on. With all other
appliances turned off, the pressure
to the refrigerator should not
exceed 12 inches water column. To
check the gas pressure when the
refrigerator is operating, there is a
pressure test housing located just
prior to the orifice.

SECTION 7
LP GAS COMPONENTS
7.1 SHUT-OFF VALVE
This is the valve where the incoming LP gas supply is
attached. To check the shut-off valve, remove and
inspect for any obstructions.
Manual Gas
Shut-Off Valve
7.2 FILTER
A filter is located in the inlet fitting to the thermostat. It
protects the internal valve portion of the thermostat by
collecting any particles and/or oil that could get into the
LP gas line. The filter can become saturated and cause
a restriction to gas flow. This could cause a lack of
cooling on gas mode. If you suspect a restriction, first
verify the thermostat (See Sec. 7.3) is good. If the
thermostat is good, and filter is restricted, replace
thermostat.
