A very important function of the igniter
assembly is to measure the condition of the
flame. The flame completes the high voltage
circuit and the spark stops when enough flame
is present.

If all of the diagnostic steps have been
completed with positive results and you are
still experiencing lack of cooling, be sure the
orifice, burner and flue tube have been
cleaned. To clean the orifice use an alcohol
based solvent and air. NEVER use a drill bit
or jet tip cleaner to clean any orifice, as these
devices will damage the factory machined part
and CREATE A POTENTIALLY
DANGEROUS SITUATION.

To properly clean the flue tube we would
suggest obtaining a flue brush. The part is
available through your local
Dometic/Duo-
Therm distributor.

Now that we understand how to troubleshoot
and repair the A.E.S. controls, do not forget
that you must have the basics of proper heat,
ventilation and leveling for the absorption
cooling unit to operate effectively.
