A light machine oil (Singer sewing machine oil) applied with a syringe (possibly with a big-bore needle for accuracy) is far better. But it does free up sticky or stuck drive spindles. 1 Link to comment Share on other sites More sharing options...

It is my 80 year old body and slowly failing eyesight that is letting me down nowadays. I'm only 65, but various bits are failing or falling off, sadly most can't be replaced using parts off Lazada 😞 Yeah, I don't do ladders and heavy lifting and I need optical assistance (use the phone camera to even read the instructions that come with some kit), but I have family to do the stuff I can't. 2 1 Link to comment Share on other sites More sharing options...

I can still do ladders though normally no higher than 3 treads. I did 4 treads this morning but I was definitely unhappy about that. For instructions I normally scan them into my computer and increase the text size. In settings I have already increased from 100% to 125% as my standard and sometimes to 150% and even 175% for some texts. It is an age thing and gets to most people in time. 1 Link to comment Share on other sites More sharing options...

Each to his own of course, but one wonders why you are even looking here 🙂 That's the trouble with this forum, no sense of humor. 2 Link to comment Share on other sites More sharing options...

steven100 Posted June 3 Author Share Posted June 3 new fan Capacitor update : replaced the capacitor with a new one and nothing changed, it still doesn't work. I may take it to a repair shop and get them to fix it ..... 1 Link to comment Share on other sites More sharing options...

Next stop, the thermal fuse, on Hatari fans these are simply zip-tied to the windings and are relatively easy (ok awfully fiddly) to replace. 1 Link to comment Share on other sites More sharing options...

steven100 Posted June 4 Author Share Posted June 4 The thermal fuse could be located in one of those insulated wire covers, but rather than cut the winding strings I'll make sure it's not located near the speed switch on the pedestal shaft first.

Update ..... after loosening the screws holding the winding together ... then plug it in and switch on 1 ... I get a slight buzzing noise, 2 .. strong buzz ... and 3 it's buzzing ... so It's not the thermal fuse either I don't believe .... I think it's the motor shaft alignment or the winding alignment as it's trying but just won't force to spin. Link to comment Share on other sites More sharing options...
steven100 Posted June 4 Author Share Posted June 4 Tried again .... loosened all the fixing bolts to the winding casing .... loosened the back spindle screws ... baby oil down the front bearing .... got plenty of buzzing on 3 ..... but no power to the shaft or very very minor ..... oh well ' I did try ... but sadly it's either the rubbish bin or the pop repair shop ...

I'd say the former....sounds like one of the windings are open circuit if all the previous has been checked and eliminated. They look fine but a multimeter test would confirm continuity. Split the windings at the common and test with a megger to make sure no shorts between the two there to be absolutely certain. Then test with growler for interwinding short within each field winding. As many said before, bin it. Edited June 4 by bluejets Link to comment Share on other sites More sharing options...

What's a "growler", we have two "Yappers" but when they "growl" it's almost comical 🙂 EDIT Wiki answered my question https://en.wikipedia.org/wiki/Growler_(electrical_device) Never come across one, but I've never been into motors either. 1 Link to comment Share on other sites More sharing options...

I could remove the motor and go and buy a new motor at Amorn .... Link to comment Share on other sites More sharing options...
