Check
Check hubber
Take of the burner so that the
light sensor can „see" light and
chose the menu point "Actual
light strength" in the controller
menu: check if the value is
beyond 05.
Be certain that all other
conditions are within spec to
make an ignition work. Let the
burner start.
Check connections between the
controller and the motor.
Eventually take of the motor
and try by hand to turn the
auger (fx using a tongs)
If a multi-meter is available
check the resistance across the
sensor (take off the plug on the
electrical connection plate (see
paragraph 9.2)).
