I had a similar problem on mine. The terminal inside the plastic cap on the temp sensor had corroded and eventually the wire just broke off. I found the temp sensor to be not screwed in very tightly. I believe it had been leaking a tiny amount of water around the threads for a long time, which eventually corroded the wire. I repaired the wire and terminal by careful soldering and replaced the sensor just for good measure using a small amount of liquid teflon type thread sealant. (I forget what it's called, PTF or PTL or something like that.) I tightened it as tightly as one dares tighten a brass threaded part (which isn't too tight.) No problem since repair about a year ago.
