Samsung Hood Error Code E-41

The E-41 error code on a Samsung hood indicates an open circuit condition in the Easy/PH sensor circuit. An "open" error means the control board is detecting no continuity through the sensor loop, which can result from a broken wire, a failed sensor, or a disconnected connector somewhere along the sensor wiring harness. The Easy/PH sensor is associated with the hood's automatic operation system, which monitors cooking conditions and adjusts fan speed or other functions accordingly.

When the control board sends a signal through the sensor circuit and receives no return signal, it interprets this as an open circuit fault and triggers E-41. This is distinct from a short-circuit error, where the resistance would read near zero. An open circuit means resistance has climbed to an effectively infinite level, breaking the signal path entirely. Common culprits include a sensor that has burned out internally, a wire that has become corroded or physically broken, or a connector that has vibrated loose over time.

Diagnosing this error typically involves inspecting the wiring harness between the sensor and the control board for visible damage, checking connector seats for proper engagement, and using a multimeter to measure continuity through the sensor itself. If the sensor reads open with no continuity, replacement is required. If the sensor measures within a normal resistance range, the fault likely lies in the wiring or the control board connection points.
