Samsung Hood Error Code E-22

E-22 on a Samsung hood indicates a temperature sensor short circuit error. The control board has detected that the temperature sensor circuit is reading outside its expected resistance range, specifically showing a shorted condition. The hood will not operate normally until this fault is diagnosed and resolved. The issue can originate at the sensor, the wiring harness, or the connectors.

You should not continue using the hood while E-22 is active. The temperature sensor is part of the hood's thermal protection system, and operating without reliable temperature monitoring could allow internal components to overheat without the hood responding correctly. Discontinue use until the sensor fault has been resolved.

A power reset may temporarily clear the E-22 code, but if the underlying short circuit condition still exists in the sensor or wiring, the error will return once the control board re-evaluates the sensor circuit. A reset alone is not a repair. The sensor, harness, and connectors need to be physically inspected and tested to permanently resolve the fault.

A knowledgeable DIYer comfortable with basic electrical testing can inspect the wiring harness and connectors for visible damage, and use a multimeter to test the resistance of the temperature sensor. If the wiring and connectors appear fine but the sensor reads near-zero resistance, replacing the sensor is a straightforward repair. Control board replacement is more involved and may be better suited to a qualified technician.

Repair costs depend on which component has failed. A replacement temperature sensor typically costs between $15 and $60 for the part. If the control board is at fault, parts can range from $80 to $200 or more. Adding professional labor, total repair costs generally range from $100 to $350 depending on the diagnosis and your location.
