If you plug the sensor into the board (so it has power), then wave a metal object (screwdriver tip should work nicely) very close to the head of the sensor, the light should go on if it's reading.

<p>I'm looking for some help with an ID3 Glacier Point 3D printer that I currently use. The hall sensors on one end of the X and Y axes have stopped functioning. I need to diagnose and confirm that the hall sensors are faulty before I can replace them (work stipulation.) I'm wondering if anyone can point me in the direction of some diagnostic technique to detect faulty hall sensors? Google hasn't been much of an aid here, unfortunately.

A photo of the sensor might help. Does the firmware show any diagnostics for this sensor with the axis positioning information?

I am. I was able to isolate the bad sensor using a continuity test (simple, but I'm new to this.) Attached is the bad sensor that I took out. It's a long shot, but I don't suppose you'd know where I can find a replacement sensor?
