Hi
I have an AC blower/heater industrial, which I think needs a capacitor. There are 4x wires brown blue green and black. If I connect the brown blue and green it hums, and if I spin it it runs halfheartedly, and gets hot. I assume I need a capacitor. Does it go between the red and black wires?
A diagram would help, please, unless I'm correct.
I have attached photo of a similar motor, as an example.
Regards, Camerart.

 

Green is Earth, measure the resistance between the Brown, Blue, Black wires, the lowest reading goes across the Live and Neutral, the other wire in series with the capacitor to Live.

Hi D,
Ok, thanks. Capacitor ordered.

Ensure it is AC motor run rated Cap, preferably non-Chinese origin!

Hi M,
Too late it's on order from lil' ol' China.

You should have ordered a dozen!
