The Door Switch is an OEM part for GE dryers, designed to ensure the dryer does not operate when the door is open. This safety feature is crucial for preventing accidents and ensuring the appliance operates efficiently and safely. The switch signals the dryer's control system about the status of the door—if it's open or closed—thereby allowing or preventing the start of a drying cycle.  Causes of damage to the door switch often include mechanical wear from repeated use, accidental damage from loading or unloading, or electrical issues such as short circuits.  Symptoms of a bad Door Switch include: The dryer not starting when the door is closed  The dryer continuing to run when the door is opened Unusual noises or the dryer stopping mid-cycle This OEM GE part is also compatible with Hotpoint, RCA, and some Kenmore models.This part fixes the following symptomsDoesn't shut offWon't startPart Number WE4M415 (AP4366862) replaces 1472475, AH2344321, EA2344321, PS2344321, WE04M0126, WE04M0157, WE4M126, WE4M157, WE4M335, WE4M337, WE4M349.
