For those who want the gritty details...

Ah. Good, two more things to look out for regarding the fan. Time to pop the cases off again and do some preventative maintenance.

I finally got my 2nd MMM to program. I ended up reseting the parameters on my DX3R and the MMM found neutral. I'm still not sure why I didn't have this problem with my first MMM, but eveything's working fine now.

Thanks for all your input Patrick. It's great having your help in this forum!
