[Kraftwerk]

Just to follow up. The motor is fixed and running perfectly. I thought I should tell you what I discovered (so many threads here trail off and you never know what the heck happened, right?) I took the fan to the work bench opened it up. Right away, it seemed like it could use a good cleaning some dust was in there and some grease and some greasy-dust. It is a fairly simply thing to dissect and very well engineered. No plastic, logically constructed, probably 30 years old or more and made in USA. So, worth fixing. I worked at it for six hours at my work bench in 90 heat. One thing which seemed suspect was the centrifugal switch (Turns out there are no capacitors) This thing has a self regulating motor, so when the switch spins 800 rpms it turns the motor onto full running speed and shuts the switch off. Genius. Very durable design. So I cleaned the switch, it was a bit gummed up which took effort and delayed the turn-on. Much better now. After I had cleaned everything I began to put it all back together and found the REAL problem: a bit of wire to the core had lost its insulation and was grounding out on the motor body. Duh, so simple. Easy fix: cut the wire, re-twisted the wire together after slipping on heat-shrink to cover the whole thing. Motor works well is as quiet as ever spins the fan blade with out issue. Glad I didn't spring for that $75. (or $230!) Chinese crap, This Ohio- built product will run awhile I think. Thank you for all your ideas and input. Moral of the story: if it was made in USA, you might get lucky. All it cost was my time.

(ps. sorry not to post photos my Apple product is pissed off at me since I recently reached a 'fully loaded cloud capacity'. A problem for another day)
