High-Limit Temperature Sensor
The 'Sn1' code is the specific diagnostic flag for the High-Limit sensor circuit. This sensor monitors the heater manifold temperature; when its internal thermistor fails or the wire harness degrades, the control board disables the heater as a safety precaution. Replacing this sensor restores the closed-loop safety circuit.

Water Temperature Sensor
While 'Sn1' refers to the high-limit sensor, this water temperature sensor is located in the same environment and utilizes the same thermistor technology. These sensors frequently fail in tandem due to chemical exposure and thermal cycling; replacing both ensures the control board receives accurate differential data.

Main Control Board
If new sensors do not clear the 'Sn1' code, the failure likely resides in the logic processing unit of the PCB. Electrolytic capacitors or the analog-to-digital converter pins associated with the sensor headers can fail, preventing the board from correctly interpreting the sensor's resistance values.
