(4) Burner Ignitors
The ignitor module provides high voltage
pulses for the top burner igniters only. CAU-
TION: Do not attempt to measure the high
voltage output of the module.
When a burner knob is turned to the LITE
position, the ignitor switch on the valve stem
closes, and provides power to the module.
Internally, power is applied to a rectifier charg-
ing circuit, that pulses a step-up transformer
two or three times-per-second. The secondary
of the transformer has two windings, one for
each pair of maintop burner igniters. With two
outputs, one set of igniters can spark without
the other set sparking. There are no adjust-
ments for the ignitor module.
