(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.
