Coritrols Inside Norcold Refrigerator
Your Dometic RM100 model incorporates a
unique, fully automatic defrosting device
for the general food storage compartment,
which eliminates the necessity for manual
defrosting at frequent intervals normally
associated with most conventional refrigerators
in the medium size range. Furthermore, the
time interval of each defrosting cycle, and the
frequency, have been so arranged that during
defrosting there is no noticeable effect upon
the temperature of the foods stored in the
refrigerator, and the frozen food storage
conditions can be maintained at all times in
the frozen storage compartment.
The following are some trouble shooting tips for
emergency use only. They relate to gas
operation and should normally be done by the
dealer.
Problem: Flame goes out. The thermostat is out
of adjustment. To adjust it, turn the dial to
"zero". If the flame does not go down to the
"low" by-pass setting, follow this procedure
(See Fig. 2.):
1
.
Unscrew the large cap screw at the rear of
the thermostat and remove the valve.
Clean the seat and valve, and replace.
2. If procedure (1
) does not correct the
problem, adjust the set screw out (in
counterclockwise direction) until the flame
goes down to the "low" position.
If the flame keeps going out when the dial is
turned to (0), remove and clean the by-pass
screw which is located as shown in Fig. 2.
Problem: Burner does not light. Remove and
clean the burner barrel, and/or check the
gas supply.
It is important that when the vehicle is
parked or stopped for any length of time it
must be properly leveled. Level the freezer
plate using a small pocket level and adjust the
vehicle so that the freezer plate is level in each
direction.
Normal installation of the refrigerator is such
that the freezer plate is parallel to the vehicle
floor. If this is evident then leveling the vehicle
will automatically level the refr~gerator and
cooling performance will be satisfactory.
While the refrigerator must be level when the
vehicle is stopped, performance during transit
is not normally affected.
It must be noted, however, that a
prolonged travel either up or down hill will
initiate a defrost cycle as the washing
motion in this case can not prevent liquid
traps and blockage.
The combination gas and electric models
employ the same refrigeralion system. The gas
controls are independent of the electric and the
electric completely independent of the gas.
One thermostat controls the desired cooling
temperature on both heat sources
. . .
gas or
120 AC.
The electric and gas control are so designed
that single operation of the refrigerator on
either of the heat sources is assured. It is not
possible to operate the unit on both gas and
electric simultaneously.
