Samsung E-11 Error Code | Fast & Reliable Repair

Error Code Explained

What Does the Samsung E-11 Error Code Mean?

The E-11 error code on a Samsung microwave indicates a fault with the humidity or moisture sensor used by the Sensor Cook / Auto Cook functions. Samsung microwaves with sensor cooking use a humidity sensor to detect steam emitted by food and automatically adjust cooking time and power level.

E-11 disables sensor cook modes but does not prevent the microwave from operating in manual mode (setting time and power level directly). It is less urgent than SE but should be addressed to restore full functionality.

Root Causes

Common Causes of the Samsung E-11 Error Code

1

Failed Humidity Sensor

The cavity humidity sensor has failed or its resistance has drifted out of specification.
2

Grease or Food Residue on Sensor

A thick layer of grease or food splatter on the sensor surface can interfere with humidity detection, causing E-11.
3

Wiring Fault to Sensor

The sensor wiring harness has developed a fault.

Step-by-Step Guide

How to Troubleshoot the E-11 Error Code

⚠️

Safety First: Always disconnect the Microwave from power before inspecting any internal components. Do not attempt electrical repairs. If in doubt, call a certified technician.

1

Clean the microwave cavity

Wipe down the full interior cavity, paying special attention to the ceiling and side walls where the humidity sensor port is typically located (usually a small grill or vent). Use a damp cloth to remove grease buildup over the sensor area.
2

Perform a power reset

Unplug for 60 seconds and restore power. If E-11 was caused by a temporary sensor reading during a high-steam cooking event, a reset may clear it.

When to Call a Samsung Technician

⚠ Stop DIY if any of these apply

If E-11 persists after cleaning and reset, the humidity sensor has failed and requires replacement. Sensor replacement requires opening the microwave cabinet — this must be performed by a certified technician due to the high-voltage capacitor inside.

FAQ

Frequently Asked Questions — Samsung E-11

Yes — manual cooking modes (entering time and power level directly) continue to function with E-11. Only Sensor Cook / Auto Cook modes are disabled. If you rarely use sensor cooking, E-11 can be addressed at your convenience.
No. E-11 is specific to the humidity sensor used for auto-cooking features. The magnetron and core heating system are unaffected. The microwave heats normally in manual mode.
Yes — a thick grease layer over the humidity sensor port can prevent steam from reaching the sensor, causing inaccurate readings and E-11. Regular cavity cleaning prevents this. Clean the cavity interior every 2–4 weeks depending on use.
