I tried everything I can think of, pics of meter ,capacitor and motor to fan.

Ok here goes . I don't know much about this subject but very handy and don't like to throw stuff away and will always try to fix it before throwing it out.

I watched several YT videos and read your Ebook and I'm still lost.

I have a Honeywell HS-1655 pedestal Fan . After awhile blades took awhile to get going when starting. I always thought it just needed to be oiled. Well one day last week it just stopped spinning but fan would turn on and was able to change speeds but blades would never turn again.

So I took it apart and blade shaft was really hard to turn and thought yes easy fix it needs to be oiled. So I oiled it and waited a awhile and blades and shaft were now moving freely ,YES !

I put it back together and nothing ,same as before :{

So that's when I started to watch YT videos and decided to buy a capacitor , same one ,
CBB61 3uf 250VAC . So I temp hardwired to test before soldering it,nothing ,same crap. Controls work just as before but blades won't turn. So I search for my meter to test the capacitor and look for instructions on how to test a fan capacitor ,set to ohms at 200k from what I understood.

My meter has ohms but no setting for 200k but I set it to max and without max. I test both capacitors old and new on ohms setting ,nothing stays at 0 . So I put fresh batteries in meter, still no reading. I short out leads and the bars on bottom react so meter is good.

So I move the selector on meter to 12 O'clock [as this stage I'm moving selector everywhere to see any reading} and get a reading of 2.952 that looks like it might be correct, within 5% of 3uf . Both capacitors old and new get readings at this setting.

I don't know what setting this is called .This is my meter {see pic} maybe someone here can help me figure this out. and if 12 O'clock on meter is the correct choice. I also attached pic of meter, capacitor and what the motor model is.

Thanks for your time.

Unless you already did it, the rotor needs to be removed completely for the bronze bearings to be cleaned and oiled properly, Also it could be a case of wear.
with no power, the rotor could be centralized, but if there is wear on the bearings, the rotor could be attracted to one side of the stator.
What happens when you turn it or try to spin it when applying power?

Well there is power because I can change the settings on fan but blades don't turn at all. Nothing happens when I try to spin blades ,they just turn freely with poser on but they never get going,its as if no power to shaft.

Sorry,what do you mean by rotor? Thanks

The readings look normal.
If you have changed the cap for the same type and value, motor start rated version, then it most likely is not the cause.
Why is the readings at that selector setting and not at Ohms ? I thought to test a fan capacitor it had to be at ohms,please explain as this is all new to me. Thanks.

The blades are operated by the rotor, (the part of the motor that spins!).
So with power applied, there is no resistance to turning the shaft? Or IOW, does it seem as no force is applied to the rotot?
It could be in the switching, i.e. open circuit etc?

You only use ohms range to test a capacitor if you believe it is shorted, if good, it will test open circuit.
With the meter at 12oclock, it measure capacity.

With power blades turn freely same as if no power . Before they wouldn't turn at all ,very hard to turn but after oil job blades turn freely with power or no power.

So my next thing is to take apart fan where the controls are and to test for an open circuit ? Any links to show me how to do that ?

Thanks so much for your time.

I don't know of any specific, just a case of carefully take apart and measure the from the source of the supply through the control to motor.
It could be a variable speed, separate motor windings or a semi conductor control.

Yes it is a 5 speed oscillating ped fan, and I have no idea what motor windings and semi conductor control are. I also don't know how to measure the from the source of the supply through the control to motor. So I'm lost here.

I tried my best to figure this out ,watched tons of videos and read many DIY before asking for assistance .I took apart entire thing and oil it {yes I removed shaft } even bought new capacitor after oil job fail.

Thanks for your time and help ,much appreciated .

At this stage I give up and going to throw it out as I can't test for open circuits if I don't know how to test it. I feel like flinging it out the window,wasted so much time on it.

Not your fault ,I just can't spend anymore time on this .
