What Does It Mean When My LG Microwave Shows an Error Code?

Microwaves are built to make life easier—until they flash an error code and stop heating your leftovers. If you’re staring at strange letters and numbers on your LG microwave display, don’t panic. These codes are your microwave’s way of saying, “Hey, something’s wrong.” Let’s break down what these error codes mean and what to do next.

Why is my LG microwave showing an error code?

LG microwaves display error codes to help diagnose internal problems. Each code corresponds to a specific issue, such as a faulty door sensor, overheating, or a blown fuse. Instead of guessing, these codes guide you (or your technician) toward a quick fix.

What are common LG microwave error codes?

Here are a few you might see:

F3 – Temperature Sensor Error
The sensor may be faulty or not reading correctly. It usually requires replacement.
F4 – Humidity Sensor Error
This typically shows up when the sensor can’t detect humidity levels. You may need a new sensor or a control board check.
F9 – Magnetron or Inverter Error
These are critical components for heating. This code usually means professional service is needed.
E-11 – Touchpad Error
This can happen if the control panel isn’t responding properly. Resetting the microwave might help temporarily.

Can I fix an LG microwave error code myself?

Sometimes. Try these first:

Reset the microwave by unplugging it for a minute and plugging it back in.
Check the door to make sure it’s closing tightly—many error codes are door-related.
Avoid use if sparks or burning smells occur—that’s a sign to stop and call a pro.

If the error returns after a reset or affects critical parts like the magnetron, call a technician.

When should I call a technician?

If the code involves internal sensors, the inverter, or heating components, it’s best not to risk a DIY fix. Strong Arm Appliance Repair has the tools, parts, and know-how to safely repair LG microwaves and clear those codes for good.
