Error Code Explained

What Does the Samsung E-13 Error Code Mean?

The E-13 error code on a Samsung microwave indicates a humidity sensor (also called a moisture or steam sensor) fault. Samsung microwaves with sensor cooking use a humidity sensor to detect steam released by food and automatically stop cooking when the food is done. When the sensor fails, E-13 appears and sensor-based cooking modes are disabled.

Root Causes

Common Causes of the Samsung E-13 Error Code

1

Failed Humidity Sensor

The sensor element has broken or its output signal is outside the expected range.
2

Sensor Contamination

Grease or food residue has coated the sensor, blocking its ability to detect steam.
3

Sensor Wiring Fault

The wire harness connecting the sensor to the control board has a loose connection.

Step-by-Step Guide

How to Troubleshoot the E-13 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 interior

Wipe down the interior cavity completely, paying attention to the top wall where the humidity sensor is typically located (a small rectangular opening). Remove any grease buildup from around it.
2

Power reset

Unplug for 5 minutes and reconnect. A transient sensor read error may clear.

When to Call a Samsung Technician

⚠ Stop DIY if any of these apply

If E-13 persists, the humidity sensor requires replacement. The sensor is inside the microwave cavity and replacement requires disassembly by a technician trained in microwave safety (capacitor discharge required).

FAQ

Frequently Asked Questions — Samsung E-13

Yes — E-13 disables sensor cooking modes (Auto Cook, Sensor Cook) but manual timed cooking continues to function normally.
It detects the steam released by food during cooking. When steam output drops (food is done), the microwave automatically stops. This prevents overcooked or exploded food in sensor cooking programs.
