Samsung Hood Error Code E-42

E-42 on a Samsung hood indicates a short circuit error in the Easy/PH sensor circuit. The control board has detected an abnormally low resistance condition in the sensor wiring or the sensor itself. This fault causes the hood to interrupt normal operation until the short is identified and corrected.

A short circuit in any sensor circuit is an electrical fault, and continuing to run the appliance is not recommended until the cause is identified. Using the hood with an active short could risk further damage to the control board or wiring. It is best to stop using the appliance and have the fault diagnosed before resuming normal operation.

Repair costs depend on the root cause. Cleaning a contaminated connector is essentially free if done yourself, while a replacement sensor or wiring harness typically costs between $20 and $80 for parts. If a control board replacement is needed, parts costs can range from $80 to $200 or more. Adding professional labor generally brings total repair costs to between $100 and $300 depending on the parts required and local service rates.

Some causes of E-42, such as a grease-contaminated connector, can be cleaned and resolved by a mechanically inclined homeowner. However, testing sensor resistance with a multimeter and tracing wiring faults inside the hood cabinet requires basic electrical knowledge and comfort working with appliance wiring. If you are not confident working with electrical components, a qualified appliance technician should handle the diagnosis and repair.

Power cycling the hood may temporarily clear the error display, but if the short circuit condition in the sensor circuit still exists, the E-42 code will return. A reset does not repair damaged wiring, a failed sensor, or a contaminated connector. The underlying electrical fault must be corrected for the error to clear permanently.
