Thanks Frank for pointing me to the AT2 manual. All fifty-seven pages of it!! I was not aware of it being on the site. I can't find any reference or link to it in the REPAIR section of the site under Air Conditioning. That's where I found the MTSC booklet on ATII. (Maybe a link is there, but I can't find it. It certainly ought to be.) The manual combined with Kenyon's loaner factory tester will be a fantastic resource to club members with ATII!!!

Btw, getting the fan out is not as difficult as you might think. You just have to take the ps-wheel off and remove the plastic mud guard.
