Microwave displays E2 and may not allow sensor cooking 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 or open humidity sensor, Damaged sensor wiring, Control board analog-to-digital converter fault

Safety First: Unplug the microwave before inspection.

Try non-sensor modes: Test manual time cook. If manual modes work but sensor modes fail with E2, the humidity sensor is suspect.
Clean sensor area: Thoroughly clean the interior, especially near the sensor grill or cover.
Inspect and reseat harness: Check the sensor harness for damage and reseat the connector on the control board.
Replace sensor: Install a new humidity sensor if the error persists. If E2 remains, the control board likely has a sensor circuit fault and must be replaced.
