This is the best solution I could find for the left hand thread problem (as posted earlier in this thread):

American Water Heater Company Gas Enhancement Kit 4040T NG

I had to drive an hour to a Lowe's that had the part, but it is worth it to have hot water again. It works perfectly, other than I can't fit my old external cover on now. It includes the adapter to change it from a left hand thread to a right hand and was pretty inexpensive. Apparently American Water Heater Company has some sort of safety detection device built into the left hand thread and this enhancement kit maintains that functionality while changing it to a right had thread.

The thermocouple on my 7yo Whirlpool water heater went out Sat. The stores open
on the weekend had only right hand thread thermocouples, and as far as I could
find out, the manufacturer would sell me a conversion kit for $31 which would
take 10 days to receive. (out of warrantee)

My solution: I carefully clamped the threaded fitting on my old thermocouple
end-to-end in my vice so one face was up, then used a 1" cutting disc in my
dremel tool to cut a slot into the fitting so I could slide it off of the tube.
I slid the threaded fitting on my new thermocouple down out of the way, then
slipped the slotted one over the tube and carefully screwed it into the valve
fitting. It works perfectly.

If you have a several years old Whirlpool or American Products water heater, you
might want to check to see if it has the left hand thread on the thermocouple.
If it does, and it is still in warrantee, contact the manufacturer now so you
can get the conversion kit for free ahead of the time you really need it.
