Trying to repair a Hyperkin Duke Xbox controller where the left trigger doesn’t respond. Found that the resistance of this potentiometer doesn’t change when it’s moved, so I’m looking to replace it. I’m a novice with this stuff though and I’m having trouble identifying it. Any help is appreciated.

    Are sure you’re measuring across the correct terminals? The resistance between the two terminals of the resistive portion is constant. I would expect the resistance of a failed pot to either be zero or infinite

      There’s a test pad on the PCB labeled “LT” (left trigger). I used that and compared it’s resistance to ground to that of the right trigger’s test pad. I got about 6-10k ohms on the working one (right trigger), and 3.9-4.4 on this one.
