2 Function
2.1 Gas Unit
2.1.1 Gas Solenoid Valve (Y57)
 In gas dryers, gas solenoid valve Y57 is activated via heater relays 1K1/1
and 2K1/1.
 Gas solenoid valve Y57 consists of gas solenoid valves Y57/1 and Y57/2.
 Gas solenoid valve Y57/1, in turn, consists of a maintaining coil and a
booster coil.
 Gas solenoid valve Y57 only opens when both solenoid valves (Y57/1
and Y57/2) are opened.
 Gas solenoid valve Y57/1 only opens when its maintaining and booster
coils carry voltage.
 Once gas solenoid valve Y57/1 is open, it remains in this state as long as
its maintaining coil carries voltage.
