Supco DE353 Dryer Flame Sensor

The Supco DE353 Dryer Flame Sensor is a flame detection component used in gas-fired laundry dryer heating units to verify burner flame presence during operation in HVAC systems. It is installed in compatible equipment where it monitors combustion at the burner assembly and sends a signal to the control system to confirm that ignition has occurred and remains stable. Positioned directly in the flame path, the sensor works as part of the safety control circuit alongside the igniter, and main control board to support controlled heating operation. It is used in residential dryers and heating applications.
