MAIN BOARD
On electronic units, two types of main boards have been
used: 115 volt AC and DC volt controlled.

NOTE: The PAL tester with the air conditioning module
attached, will allow for proper testing of communication
integrity between the control board and main board. The
PAL and the AIR CONDITIONER MODULE are available
from your Dometic parts distributor.
To check this main board, disconnect all power to the air
conditioner. Remove the fan speed wires and the
compressor wire from the main board. Set the control
board to COOL and HIGH FAN positions. Connect
power to the air conditioner. Verify the lights on the
control board are on. If no lights are lit, remove control
board and attach directly into main board ribbon cable.
If lights do not come on, replace main board. With lights
on control board, use a 115 AC volt incandescent bulb
with one lead to the AC WHITE terminal and the other
lead on HIGH and then to compressor terminal to verify
the circuit is being completed through the main board.
Switch the control pad to other settings and verify all
circuits are being completed. If not, replace the main
board.

NOTE: The PAL tester with the air conditioning module
attached, will allow for proper testing of communication
integrity between the control board and main board. The
PAL and the AIR CONDITIONER MODULE are available
from your Dometic parts distributor.
This main board is controlled by DC volts supplied from
the control board. To check DC volts, be sure OFF/ON
switch on control board is "ON". Measure the outside
(#1 [+] and #10 [–]) terminals on the cable between the
main board and the control board. The operating range
is 10 to 16 volts DC. If DC volts are not within this range,
correct the DC volt supply.
To check the circuit completing capabilities of the main
board, first disconnect all power to the air conditioner.
Then remove the fan speed wires and the compressor
wire from the main board. Set the control board to
COOL and HIGH FAN positions. Next, connect power
to the air conditioner. Verify the lights on the control
board are on. If no lights are on, remove control board
and attach directly into the main board ribbon cable. If
lights do not come on, replace the main board. With
lights on control board, use a 115 AC volt incandescent
bulb with one lead to the AC WHITE wire and the other
lead on HIGH terminal and then to compressor terminal
to verify the circuit is being completed through the main
board. Switch the control board to other settings and
verify all circuits are being completed according to the
operation manual for the specific model you are diag-
nosing. If not, replace the main board. If the circuits are
being completed, DO NOT replace the main board.

NOTE: When the control board fan setting is in the
AUTO mode, the fan motor will cycle OFF and ON with
the compressor cycle. There is a two minute delay on
start after the control board senses cooling is needed.
