It detects the machine’s rotating movement and provides RPM speed information to the equipment’s control system. If your elliptical has a faulty, damaged, or missing speed sensor, this part may help restore accurate speed detection and normal sensor operation.
This product carries the NordicTrack brand and is identified by part number and SKU **SS339**. The product listing names it specifically for the **NordicTrack 831.29894 elliptical**.
Product Details and Benefits
The SS339 is an **elliptical RPM speed sensor**. Its main function is to sense rotational speed within the exercise machine. The sensor supports the equipment’s ability to monitor movement while the elliptical operates.
A functioning RPM sensor helps the machine receive speed-related information from the moving mechanism. When the original sensor stops working correctly, the elliptical may not detect movement as expected. Replacing the sensor with a matching part can help address a sensor-related fault without replacing the entire machine.
This part is useful for customers repairing or maintaining a NordicTrack elliptical and for technicians sourcing a specific replacement component. Its clearly identified part number makes it easier to compare the replacement with the component currently installed in your equipment.
