Spray that sucker with some lightweight oil, such as (at least - WD-40; better - Liquid Wrench; best - Kroil or some such thing) Let it set for a while, then spray again. Take yourself a Stilson wrench (pipe wrench) and put a bit of pressure on the sensor. Start tapping the wrench with a smallish hammer. Do the "Anvil Chorus" a few times, while spraying (soaking) again a couple times. This should break loose all of the rust, sludge, and other crap that's binding the threads. If still not free, fit a 2" diameter by 6' long steel pipe (like for chain link fences) over the end of the wrench, and gently (you have a lot of mechanical advantage now) increase the pressure on the wrench. If still no luck, you'll probably need to buy a new pipe - but there's always the "blue wrench"! Karl Wolz
