Capacitor Fail?????20 bloody characters.

motor runs fine if i give it a push. i assume the cap in the pic is a dual start/run. only shows 1 value (4mfd) so does that mean it's 2 x 4mfd caps in the one can? assuming that.best place to get one?

Is this it pal?

don't get big-headed though. your doors are only 2'6" wide.(that's 900 millipedes for the younger plebs).

Now seriously... I'm confused.. I had to measure my living room door width.. Mine is 680mm wide....
I work in mm... I'm no Yank..

Think you might need to recalculate that mate.

yeah, yeah. too late to edit. should be 750mm or thereabouts. bloody french dimensions. so confusing. just because they can only multiply by 10.

Hi bud,are those capacitor terminals not paired?

dunno.might just be a start cap. will know more when replacement has gone in.

Looks like a regular run cap for a PSC motor. If there's no centrifugal switch or relay, there can't be a start cap, which would usually be more than 4μF. What's the application?

motorised curtains. on a timer.when the control unit gets 240V motor runs 1 way. removal of the 240V sends motor other way. in either case motor runs if given a nudge but won.t start on it's own.

I had the same problem with my dryer. The drum would only turn if I helped it. I changed the cap for one I bought from Ebay for about £4 ish. Did the job perfect and kept the missus in a employed.lol

PSC then, two identical windings with common N, cap bridged between the two live ends. To open, C/O relay makes winding A live via limit sw, winding B becomes the cap winding. To close, relay makes B live, A becomes cap winding so phase shift is in opposite direction. Expect two leads on the cap will be the windings and the other two the feeds from the limit switches.
