Samsung Oven door — Door Open or Plunger Switch Fault

Samsung Oven · Error code door

What door Means

Samsung's official display message when the oven door isn't fully closed or the door plunger switch isn't registering. Bake/broil won't run while displayed.

Symptoms

  • 'door' shown on the display
  • Oven beeps and won't heat
  • Cycle pauses mid-cook

Common Causes

1
Door not fully closed

Door bumped open or gasket holding it ajar.

2
Failed door plunger switch

Microswitch in the frame failed.

3
Bent hinge

Door not seating squarely against the frame.

4
Wiring fault to plunger switch

Wire from switch to main PCB open.

How to Fix It

  1. Press the door firmly closed; the message should clear.
  2. Inspect the door gasket for obstructions or damage.
  3. Remove anything caught in the door (oven mitt, foil, bakeware).
  4. Open and close several times and watch that the plunger fully depresses.
  5. If the message stays even with the door closed, test the plunger switch for continuity when pressed; replace if faulty.
  6. Check the hinge for bend/sag; replace hinge if the door won't seat square.
