DRYER 9577/9588
GAS VALVE OPERATION
The gas valve is a two-stage valve. When the ignition sequence begins, the
igniter is turned on and valve one opens. When the igniter reaches 370° F
(188° C), the igniter is turned off and valve two opens. If the flame detector does
not detect ignition, valve two is closed and the process is restarted. If ignition
occurs as planned, the drying cycle will operate.
