Components.
This burner has four basic components: a sili-
con carbide (glow bar) igniter, burner tube, sensor, and a two-
stage gas valve consisting of a split-coil valve and a secon-
dary coil valve. The split-coil valve is opened when the dryer
thermostat calls for heat, while the secondary valve does not
open until the igniter has attained ignition temperature.
2.
Pre-Ignition Circuits.
When the dryer thermostat calls for
heat, circuits are completed through the holding coil, sensor,
booster coil and igniter. Both coils must be energized to open
the split-coil valve. Once opened, the holding coil can hold
the valve open without assistance from the booster coil. The
sensor triggers the current to travel around the secondary coil
and through the igniter, causing the igniter to get hot.
