✅ Cross Reference Information

Current Part Number3501W1A019S

Common Symptoms

  • Door does not latch or close securely.
  • Microwave remains in a door-open condition when the door is closed.
  • Microwave starts inconsistently when the door is closed.
  • Loose, broken, or visibly damaged latch-holder housing.
  • Interlock-related operation problems after door impact or latch wear.

Check Before Replacing

  • Disconnect power before inspecting the assembly; do not work inside a microwave unless qualified because high-voltage components can retain a lethal charge.
  • With power disconnected, inspect the door hooks, latch-holder housing, and surrounding mounting area for cracks, looseness, obstruction, or misalignment.
  • Confirm that the door closes evenly and engages the latch without excessive force or lifting the door.
  • Do not defeat or manually bypass the door interlock. If the microwave operates with the door open, stop using it and obtain professional service.
  • If electrical switch testing is required, have a qualified technician perform it according to the appliance service documentation.

Pro Tip

Because this assembly includes the latch housing and multiple interlock switches, replacing the complete assembly can address a damaged switch mount or small amount of latch-holder play that may not be corrected by replacing a switch alone.
