Electrolux Microwave Error Code E62

The E62 error code on an Electrolux microwave indicates a humidity sensor short circuit fault. The humidity sensor, sometimes called a moisture or steam sensor, is used in sensor cooking modes to detect the steam released from food and automatically adjust cooking time and power level. When the control board detects an abnormally low resistance reading from the sensor circuit, consistent with a short to ground or an internal sensor short, it flags the E62 code and halts normal operation to prevent incorrect cooking results or further component damage.

The two primary causes of this fault are a shorted humidity sensor itself or a failure within the smart board (the main control board that processes sensor signals). A shorted sensor typically results from moisture intrusion, physical damage, or component degradation over time. The smart board can also produce this fault code if its internal circuitry responsible for reading sensor input has failed, even if the sensor itself tests within normal parameters. Identifying which component is at fault requires inspecting the sensor wiring harness for damage and measuring resistance across the sensor terminals.

Diagnostic procedure begins with inspecting the humidity sensor for visible damage and checking for a short circuit using a multimeter across the sensor terminals. A properly functioning sensor should show a specific resistance range rather than near-zero ohms, which would confirm a short. If the sensor tests normal, attention shifts to the smart board, which may require replacement if its sensor input circuit has failed internally.
