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

Spark sensor
Ignition sensor
Limit switch
Main burner switch

The correct answer is: Ignition sensor

The ignition sensor is crucial in a spark ignition dryer as it plays a key role in ensuring safety and efficiency during the ignition process. Once the burner lights successfully, the ignition sensor detects the presence of the flame, which allows it to send a signal that effectively shuts off the spark igniter. This prevents unnecessary energy use and potential hazards associated with continuous spark ignition. By activating the ignition sensor, the appliance also minimizes wear and tear on the igniter, extending its lifespan. This element of control is essential in modern gas appliances to create a safe operation by confirming that the burner is indeed ignited before ceasing further ignition attempts. Understanding the function of the ignition sensor can therefore aid in both troubleshooting and operational efficiency in gas-fitted systems.
