Which device shuts off the spark igniter in a spark ignition dryer after proper ignition?

The device responsible for shutting off the spark igniter in a spark ignition dryer after proper ignition is the ignition sensor. This component plays a crucial role in safety and efficiency by detecting when the flame has been established. Once the ignition sensor confirms that the flame is present, it signals the system to deactivate the spark igniter to prevent continuous sparking, which could pose a hazard or lead to unnecessary wear on the igniter itself. This ensures that the ignition process is both safe and energy-efficient, as the igniter is only active when needed to start the flame.

Utilizing an ignition sensor helps maintain operational safety and prevents potential risks associated with prolonged ignition attempts, such as gas buildup or excess heat generation. The proper functioning of this sensor is essential for the dryer to operate effectively and safely.

In contrast, while components like the spark sensor, limit switch, and main burner switch may have their own specific functions within the system, they do not directly control the deactivation of the spark igniter. The spark sensor monitors the presence of a flame but does not shut off the igniter; the limit switch typically regulates the temperature or pressure within the unit; and the main burner switch is more associated with turning the burner on or off rather than managing the ign
