Bosch 00623850 Dryer Door Switch

Dryer Door Switch – Bosch

The dryer door switch detects whether the dryer door is open or closed and signals the control board to allow or interrupt the dry cycle accordingly. When the door switch fails, the dryer may not start even with the door fully closed, or may run with the door open (bypassing the safety interlock). This direct-replacement door switch restores correct door-state detection and dryer safety interlock operation.
