The A1266 is the same thing as my A733. My transistor came in today and I am putting it in but I already purchased a replacement blower motor long ago to get a fast fix. Sorry but I don't think I will be in a hurry to tear the dryer down again to test this out since it is working fine, I'm hanging on to this motor as a spare for now. I posted earlier about how to test the transistor with a Fluke, look back on the earlier page. Maybe you can try one if you want to try and save the $145 and let us know. It is only a nickel and shipping from Mouser to try out! There isn't much to the circuit and from my experience these transistors fail pretty often. Jury is still out on this one though since no one has taken it all the way through and posted back with a fix.
