Explain igniter has to pull 3.5 amps before the gas valve will stay open .? ( is this part of the safety circuitry ) ?? please explain how this circuit works ? Del . No heat converted to L P gas .
Answer Del, You're discussing a gas range ignition system, not a gas dryer system. A dryer ignition system works on heat. Here's the basic operation: The neutral circuit for the gas valve and ignition system is supplied through the motor switch. The power circuit(120 VAC) is supplied through the timer and thermostats to the coils on the gas valve,and then to the igniter and Radiant/flame sensor. All of the components and circuits are "closed" at room temperature. When the dryer is started, and power is supplied to the igniter it will start to glow/heat. When the igniter reaches a temperature of 23 to 2400 degrees F., the radiant/flame sensor circuit opens, the remaining valve coil also opens and gas is released, and ignited. The igniter bar has got to be in the burner flame and needs to have a slight glow to it, during the "burn" in order to maintain the path of least resistance,and hold the gas valve coils open, and an active flame. This hould help, I hope. So you're using LP gas, was the burner assembly properly converted, WE25X217, do you have at least 10 WCI gas pressure at the gas valve, and does the igniter cycle on, and off, without an ignition or flame. Thanks and Good Luck.
