Troubleshooting guide

2. The Roof Air Conditioner: There are at least two air conditioners in all
motorhomes: one on the dashboard which can be used when the engine is
running, and another on the roof, which runs only on 110V AC current. In
some Class A vehicles, there are two roof air conditioners. In most models,
there is a switch in one of the cabinets over the dinner table area that
determines which of the two you can use.
If you are running the roof A/C using the generator as your source of 110V
power and you turn the knob on the A/C from COOL to FAN, wait 2 to 3
minutes before turning this knob back to the COOL position. Otherwise, by
not waiting, the generator can become overloaded. In addition, the A/C should
not be turned on for 2 to 3 minutes after first starting the generator to allow it to
“warm up”.
Tip: In very hot weather, set the A/C temperature no lower than 65 to 70
degrees. A lower setting will not cool off the interior any faster and may
“freeze up” the A/C cooling unit, resulting in insufficient cooling.
It is perfectly fine to run the generator while driving so that the roof A/C can be
run to cool the cabin. Make sure the A/C is in the OFF position before starting
the generator. The generator is not designed to start itself along with any
other load. Starting the generator with the A/C on may “pop” the generator’s
circuit breaker which will then require a reset.
3. The Refrigerator:

The refrigerator can be operated on either LPG or 110V AC
current. It does not run on 12V DC current from the
auxiliary battery.
Note: When the vehicle is not in motion, the refrigerator
works well only when it is approximately level. Always try to
park in a level spot. Whenever you stop and plan on staying
for a while, check to see if the vehicle is level with the help of
the leveling bubble in the refrigerator. If the vehicle is not
level, lay the leveling blocks where it is lower and drive the
motorhome up onto the blocks. You do not have to make it perfect, and for a
few minutes it does not matter, but if you plan on being in one spot for any
length of time, the vehicle will need to be as level as you can make it. When the
motorhome is in motion, it does not matter if it is level or not. Do not forget to
take the leveling blocks with you when you leave.
You need to make sure the door is pushed in all the way until the door latch
catches to keep the door from opening while driving. In some models, the door
has a sliding latch that will “lock” the door and prevent it from opening. On other
models, it has a pin at the top of the door that does the same.
