Thread: Possible failed capacitor?

Something about the rating does not sound right to me given that it is on a 240v motor.

I’ll enquire about this point

Image on cap itself says 450v so about right.

He means on my cap, not the one in the link

So where did the 125V figure come from? Was it printed on the dead cap or did someone give you that figure?

I see, my mistake.

When I was picking up the capacitors from the company I quizzed the tech about the 125V spec on the start capacitor, he said it might be the wrong capacitor for our grid, or sometimes motors have a 120v circuit for the start, I didn't press further because I have no knowledge to ask any further informed questions. But I now have a 400 uF 250V start cap and a 25 uF 250V run cap. It's been repaired and it's running fine

thanks everyone for the tips
