Why the control reported this error
The microwave control displays this fault after detecting an abnormal sensor, keypad, door, inverter, or heating condition. Check defective humidity sensor module first; grease buildup over sensor intake holes and loose wire connector at main PCB can trigger the same code and should be ruled out before replacing auto-Cook Humidity Sensor.

Common questions
Quick answers for this fault
What should I check first for E-11?
Start with defective humidity sensor module. If that checks out, continue through the diagnostic sequence above rather than replacing a part based on the code alone.
Does E-11 always mean Auto-Cook Humidity Sensor is bad?
No. An error code identifies the condition the control detected, not a guaranteed failed part. Confirm the likely causes and wiring first. The exact OEM part number varies by model and production revision. Verify the complete model number before ordering.
When should I stop troubleshooting E-11 myself?
Stop if the next step requires live electrical testing, sealed-system work, gas or combustion service, or any procedure outside your training. Unplug the appliance before removing panels or testing internal components. Do not bypass safety switches or live-test high-voltage, gas, refrigerant, or combustion components unless you are qualified to do so.
