The ERR error on your Ge Microwave means the main control board has detected an internal fault it cannot resolve on its own. This is a general control error, and in most cases a power reset will clear it, but repeat occurrences point to a deeper electronic fault.

Error code ERR
Meaning General control board error — the microwave’s electronic control has detected a fault in its internal system
Severity Medium — the microwave usually stops working until reset, but rarely causes a safety hazard
Time to fix 5–20 minutes
Tools needed None (screwdriver only if inspecting the control board)

What the ERR error means

The ERR code is GE’s generic way of telling you the control board has run into a problem it can’t identify more specifically. It could be a minor software glitch, a power surge, a sensor communication issue, or a sign that the control board itself is failing.

Because this is a catch-all error rather than a specific fault code, the first step is always a full power reset. If the error keeps coming back after resetting, the control board or a connected component likely needs professional attention.

Common causes

  • Temporary software glitch in the control board caused by a power fluctuation or surge
  • Loose or corroded wiring connection between the control board and the keypad or door switch
  • Failing control board due to age, heat damage, or moisture exposure
  • Door switch or interlock sensor sending a faulty signal to the control board
  • Recent power outage or brownout that left the microwave’s electronics in an unstable state
  • Overheating of internal components from prolonged or heavy use

How to fix the ERR error

  1. Unplug the microwave for 60 seconds. This clears the control board’s memory and resolves most temporary glitches. Plug it back in and check if the error clears.
  2. Reset via the circuit breaker. If unplugging doesn’t help, switch off the breaker feeding the microwave for a full minute, then switch it back on. This forces a deeper reset than unplugging alone.
  3. Check the door switch and latch. Open and close the door firmly several times to ensure it’s latching properly. A door switch not registering correctly can trigger a general control error.
  4. Inspect for visible damage. With the microwave unplugged, check the control panel and back vents for signs of moisture, scorch marks, or loose wiring you can safely see.
  5. Test on a different outlet. Plug the microwave into another outlet to rule out a weak or fluctuating power supply as the cause.
  6. Call a qualified appliance technician. If the ERR code returns after resetting and ruling out the door switch and power supply, the control board likely needs replacing.

FAQ

Can I keep using the microwave after an ERR error clears?
Yes, if the error clears after a reset and doesn’t return, it’s generally safe to keep using the microwave. Keep an eye out for repeat errors, which suggest a bigger issue.

Does ERR mean the microwave is unsafe to use?
Not typically. ERR is a control fault, not usually a safety shutoff. Still, if you smell burning or see sparks, unplug it immediately and don’t attempt repairs yourself.

Will a power surge protector prevent this error?
It can help. If your home has frequent power fluctuations, a surge protector reduces the chance of the control board glitching, similar to how it protects other appliances like the units covered in the Ge Washing FL Error Code: Causes and Fixes guide.
