How to adjust an elliptical reed switch

The reed switch is attached to the frame, where it senses a magnet on the rotating pulley to detect the elliptical's speed. The reed switch transmits the speed signal to the console, which displays the speed. If the console doesn't display the correct speed, the reed switch may not be close enough to detect the magnet as it passes. Adjust the reed switch alignment following the steps in this DIY repair guide.

This repair guide covers ProForm, Weslo, NordicTrack and Image elliptical exercisers.
