High Voltage Cable; Upper Circuit Board - Dometic RM2612 Service Tips Manual

HIGH VOLTAGE CABLE

Disconnect high voltage cable from electrode. If sparking starts during trial-for-ianition, the cable is
good. If there is no sparking during trial-for-ianition
there is a sparking sound from the igniter during trial-for-ianition, then replace high voltage cable.
ELECTRODE
Do a visual check for cracks or breaks on the ceramic insulator. The spark gap must be set at three
sixteenths (3/16") of an inch and tip of electrode above the slots in the burner.

UPPER CIRCUIT BOARD

NOTE: The PAL tester will allow for proper testing of the integrity of the upper and lower circuit boards.
PAL is available from your Dometic parts distributor.
With main ON/OFF switch on display panel in OFF position:
Check for DC voltage at Plug 1, Terminal 4 (orange wire) and terminal 5 (red wire) negative (-) DC on
the lower circuit board. If no voltage, then check fuse condition. Check for DC voltage between J4
and J10 terminals on the lower circuit board.
Next, check for DC voltage at the upper circuit board between terminal 4 (orange wire) and terminal 3
(red wire) which is negative (-) DC. If no voltage, and your previous check proved voltage at the lower
circuit board between these wires, replace the cable assembly.
With main ON/OFF switch on display panel in ON position:
Check for DC volts between terminal 3, red wire (-) negative and terminal 5 (green wire) and
terminal 1 (black wire). If there is no voltage, the ON/OFF switch on upper circuit board is defective.
