The E-6 error on your Ge Microwave means the control board has detected a problem with one of the door interlock switches. Fix hint: this usually needs a switch replacement or a wiring check, and in most cases you should stop using the microwave until it’s resolved since the door switches are a safety feature.

Error code E-6
Meaning Door switch (interlock) error — the control board isn’t reading a correct signal from one or more of the door switches
Severity High — the microwave will not run, or may not run safely, until this is fixed
Time to fix 20–45 minutes
Tools needed Phillips screwdriver, multimeter (optional, for testing switches)

What the E-6 error means

GE microwaves use two or three interlock switches on the door to confirm it’s fully closed and latched before the magnetron can run. This is a critical safety feature that stops the microwave from operating with the door open. The E-6 code appears when the control board gets a signal that doesn’t match what it expects — for example, one switch reads “closed” while another still reads “open,” or a switch has failed and sends no signal at all.

This is similar in spirit to how appliances flag mismatched sensor readings elsewhere in the home, such as the Ge Washing UE Error Code: Causes and Fixes when a washer detects an unbalanced load reading.

Common causes

  • A worn or failed primary, secondary, or monitor door switch
  • A door latch that’s misaligned so it doesn’t fully engage the switches
  • Loose or corroded wiring connections at the switch harness
  • Debris, grease, or food residue blocking the latch mechanism
  • A damaged door hinge causing the door to not close flush
  • A faulty control board that’s misreading otherwise-working switches

How to fix the E-6 error

  1. Unplug the microwave first. Door switches carry line voltage, so always disconnect power before opening the cabinet.
  2. Inspect the door and latch. Check for a bent latch, misaligned door, or buildup of grease and food debris stopping the door closing fully.
  3. Test the door switches. With the microwave unplugged, use a multimeter to check continuity on each switch as the door opens and closes — a switch that doesn’t change state is faulty.
  4. Check the wiring harness. Look for loose, corroded, or disconnected wires at the switch terminals and reseat or clean any connections.
  5. Replace the faulty switch. If one switch tests bad, replace it with the correct GE part number for your model rather than swapping in a generic switch.
  6. Call a technician if the error persists. If all switches test fine but E-6 still shows, the control board itself may need replacing, which is best left to a professional.

FAQ

Can I keep using the microwave with an E-6 error showing?
No. The door switches are a safety system, so the microwave should not be used until the fault is fixed and the door locks and seals properly.

Is this something I can fix myself?
Checking the door latch and cleaning debris is safe for most homeowners. Testing or replacing switches involves mains voltage, so if you’re not comfortable working with electrical components, it’s safer to call an appliance technician.

How much does it cost to fix a door switch error?
A door switch itself is usually inexpensive, but labour for diagnosis and replacement can vary. If the control board needs replacing instead, the repair cost is significantly higher and may be close to the price of a new microwave.
