I actually had a problem un-soldering the IN sensor. I ended up having to purchase another unit because it seems that the sensor broke off, and came apart. It was almost like the sensor was not just soldered on...but yet the wires actually went down in the unit itself. I was just checking to see if there was anyone else that had this particular problem, or was it a result of my poor handy skills....which are not bad btw.

Thanks for any advice. I'm just kinda skeptical of trying it again now lol.
