Reluctant fan

Jul 09, 2014 28 Replies

Well, I unscrewed the plastic grille from my Lasko 3733 20" box fan and there it was, a permanent split phase motor with a 250 V 4.0 microfarad capacitor. (Horrible fan. I keep it in the kitchen because I can hang it from the ceiling in a jiffy to blow smoke out the window before it stinks up the house.)

How would you switch speeds with a shaded pole motor?

...snip....

What warning was that? Just curious...

Should know better, but don't always.

Well, that makes some sense except that I know for sure that I couldn't replace my antique (might just be old) fan for $20. Yes, I could get a $20 fan but it sure wouldn't be a direct replacement for the CFM's that that thing moves. The OPs box fan? Maybe.

I agree!!!!

I am probably the cheapest bastard on earth...but I would not waste time with a seized-up motor.

Around here new box fans go for $15 and $3 at a rummage sale.

and the motor starts spinning. WD40 everything in sight in the motor, and apply some spray 3/1 oil any place you can get to near the bearings. Leave it outside for a few hours to dissipate the small, and then enjoy the fast- moving fan again.

For about two days, till the WD and three in one dry out.

Mine starts much sooner - a minute or two. Last time I started it I tried giving the blade a push. Seemed to help.

Thanks, but don't bother with the notes.

It's in my 'office' area. It only runs when I'm there.

When I say old the fans were built in the 1930's. If/when they fail again they typically slow down again.
