The DR error on your Ge Microwave means the control board is not detecting that the door is fully closed and latched. The microwave will refuse to start until this is resolved, and the fix is usually quick and doesn’t require tools.

Error code DR
Meaning Door open / door not sensed as closed
Severity Low — the microwave will not run until fixed, but it’s rarely a safety issue
Time to fix 2–15 minutes
Tools needed None (screwdriver only if latch replacement is needed)

What the DR error means

Ge microwaves use door switches (latches) to confirm the door is fully closed before allowing the appliance to run. This is a safety feature that prevents microwave energy from leaking out while the door is ajar. When the control board doesn’t receive the “door closed” signal from these switches, it displays the DR (door open) error and blocks the start function.

This error can appear even when the door looks closed, because the issue is often with the switch mechanism itself rather than the door alignment.

Common causes

  • Door not pushed fully shut or slightly misaligned
  • Door latch or hook mechanism worn, bent, or broken
  • Door switch (interlock) faulty or stuck
  • Debris, grease, or food residue blocking the latch sensor
  • Door hinge loose or damaged, preventing a proper seal
  • Control board fault misreading a working switch (less common)

How to fix the DR error

  1. Open and firmly close the door — Fully open the door, then close it firmly until you hear the latch click into place. Try this two or three times.
  2. Check for obstructions — Inspect the door edges and latch area for food debris, grease buildup, or anything preventing the door from sealing properly. Clean with a damp cloth if needed.
  3. Inspect the door latch and hooks — Look for cracked, bent, or broken plastic latch hooks on the door. These are common wear points and can prevent the switches from engaging.
  4. Unplug and reset the microwave — Unplug the unit for 60 seconds, then plug it back in. This clears the control board and can resolve a temporary sensor glitch.
  5. Test the door switches — If the error persists, the door switches themselves may be faulty. This requires removing the outer casing to access and test the switches with a multimeter — consider calling a technician if you’re not comfortable doing this.
  6. Replace faulty parts — If the latch or switch is confirmed broken, replace it with a GE-approved part. Attempting a temporary bypass is not safe on a microwave due to radiation exposure risk.

FAQ

Can I still use my microwave if the DR error appears?
No. The microwave is designed to stop working until the door is properly closed and sensed shut. This is a safety lockout, not a cosmetic error.

Is it safe to open the microwave myself to check the door switches?
You can safely inspect the visible latch and hinge areas. However, opening the casing to test internal switches involves working near a high-voltage capacitor, so this step is best left to a qualified technician unless you have experience with appliance repair.

Why does the DR error keep coming back after I close the door properly?
If closing the door firmly doesn’t clear the error, the problem is likely a worn or broken latch hook or a faulty door switch rather than user error. These parts wear out over time with repeated use and typically need replacing.
