Microwave shows E2 and may stop during sensor cooking or not start those modes.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Shorted humidity sensor, Sensor contaminated with grease or residue, Wiring harness short, Control board misreading sensor

Safety first: Unplug the microwave.

Clean cavity and sensor area: Wipe down the interior, especially near the sensor grille, to remove steam residue and grease that can affect readings.
Reset power: Unplug for 10 minutes, then reconnect and test sensor modes.
Inspect sensor: Remove the outer cabinet and inspect the sensor and wiring for damage or contamination.
Replace sensor: If E2 persists, replace the humidity/sensor cook sensor.
Control board: Persistent E2 with a new sensor may indicate a faulty main control board.
