Agreed, they all fail over time. I believe it's just a magnetic ring around the foam float that acts as a switch, and it deteriorates easily. Get a new one, it's really hit and miss with used sensors, even if they were good when removed.
You can put a jumper wire between the two wires that go to the sensor to test the rest of the circuit. The light should go off with the wires connected.
