Samsung Microwave -dr- — Door Open (Demo / Reminder)

Samsung Microwave · Error code -dr-

What -dr- Means

Display shows '-dr-' (or 'door') when a cycle is started but the door is not fully closed, or one of the door switches is not making contact.

Symptoms

  • '-dr-' or 'door' shown on display
  • Cycle won't start until door is closed
  • Sometimes shown even with door appearing closed

Common Causes

1
Door not fully latched

Push the door firmly until latch engages on both sides.

2
Food debris in door seal/latch

Crumbs or buildup keep latch from engaging.

3
Misaligned/sagging door

Hinge wear prevents proper latch engagement.

4
Failed primary interlock switch

Switch doesn't close even though latch is engaged.

How to Fix It

  1. Open and firmly re-close the door.
  2. Clean the latch hooks and switch plunger area.
  3. Inspect for door sag — gently lift while closing to test.
  4. If error persists with a closed door, unplug and test/replace the primary interlock switch.
