Electrolux Microwave Error Code E62

E62 on an Electrolux microwave indicates a humidity sensor short circuit error. The control system has detected an abnormal signal from the humidity sensor circuit that is consistent with a short. This fault points to either the humidity sensor itself or the smart board as the source of the problem.

It is not recommended to continue using the microwave while E62 is active. The fault indicates a problem in the sensor circuit, which can prevent the unit from operating correctly, particularly in sensor cooking modes. Using the unit in this condition could lead to incorrect cooking results and may mask additional developing faults.

Repair costs depend on which component has failed. Replacing a humidity sensor is generally the less expensive repair, with parts typically ranging from $15 to $50 depending on the model. Smart board replacement is more costly, with parts often ranging from $80 to $200 or more, plus labor if a technician is involved. Getting a diagnosis before ordering parts is advisable to avoid unnecessary expense.

A knowledgeable DIYer can perform initial diagnostics, including inspecting the sensor wiring harness for visible damage and checking for moisture at the connector. However, testing sensor resistance and replacing the smart board involves working inside the microwave cabinet, which contains a high-voltage capacitor that retains a dangerous charge even when unplugged. The capacitor must be safely discharged before any internal work is performed.

A power reset, such as unplugging the unit for a few minutes and restoring power, may temporarily clear the code if the fault was caused by a transient condition like moisture at the connector. However, if the humidity sensor is genuinely shorted or the smart board has failed, the E62 code will return once the microwave attempts to read the sensor again.
