F19 error
Inspect door for imbalance
or excessive resistance
Check area around operator
for adequate ventillation
space on the sides, above,
and below the operator.
Check the electronics
enclosure for dust or other
debris near or behind the
PCBA that restricts airflow
or cooling.
Measure ambient
temperature near the
powerhead when the
overheating is occurring.
Check against the
temperature range
specification for the
product.
Check that the motor
and gearbox rotate freely
and smoothly when
disconnected from the door
If OVERTEMP fault never
clears, even when the
electronics have cooled,
the main board may be
faulty.
If motor is getting
excessively hot or does
not spin smoothly when
powered, there could be an
issue with the motor

Resolution
Configure system ID in
the menu by using the
LCD wall control.
Ensure system ID
is chosen properly.
Operator may not
function properly if the
chosen system ID does
not match the operator.
Repair or correct
conditions resulting
in excessive door
imbalance/resistance
Correct any airflow
restrictions around or
inside the operator to
improve cooling of the
electronics.
Product must be used
within the specified
operating temperature
range or risk of damage
to the operator is
possible.
Correct any issues
found, or replace
any faulty or worn
components producing
excessive drag
Replace main board.
Replace motor
