AC Capacitor Source

[Neil Powell]

Hi, all. Sorry for another wildly OT post; I just can't help myself when it comes to tapping the wealth of knowledge here.

Anywho, I am struggling to find sources for a replacement for my AC capacitor in this picture

View attachment 81148

I think I need a run capacitor rated at 250V and 45 microfarads, but I am very much a novice in this realm.

Based on my assumptions above, I have Googled a little bit. And I only came up with one candidate - Ebay Capacitor. I'm not 100% certain this will be a suitable replacement. And it would be nice to have more than one option.

Any thoughts?

If you have an electric repair type place in your area they are likely to have one. Where I live we have a place the repairs a lot of different electric type things from motors to dock lifts etc and they always have them on hand

Good info. Going to look into finding one.

Why do you have to bust my balls? Make me work overtime? Shouldn't you do your own research first?

If you don't like my suggestions, find out how to put me on ignore, or just STFU.

Appreciate the leads.

It's a single cap, but each terminal can accept two leads.

That sounds right. Here's a picture of the connectors

And, fortunately, I took a picture of how the compressor was connected to it, so that I can put it back right.

In our shop as well as personally as posted above I agree Graingers is a good source for both parts plus good advice . With an old unit in hand knowing the voltage and capacitance they can help.

Thanks to you and Dick for that suggestion. I looked around a little on their website, which is a bit dizzying. But I think I'll call the local Grainger and possibly head over there.

Amazon is where I got mine for a spare to have on hand after the AC guy charged me $175 dollars to replace one.

Oof, sorry to hear about the pain on that! Amazon seems like a viable option, now that I know a little more about it, particularly that I don't need to (and probably shouldn't select a 250v) example.

The 250 spec just means it's the cheapest there is. Just go to ebay and get a round 45mf capacitor made by Mars or Supco. 370 or 440 will both be fine. These are made in Mexico which is as good as you can get now a day's.

Thanks to you and BandD. It helps a lot to know I can (and should) go up on the voltage rating.

You can get anything you want at Alice's restaurant and Amazon.

Good song And, yes, they probably should update it to include Amazon.

I know my local HVAC man has a fishing tackle box in his truck that's filled with capacitors with dozens of different ratings. When the temp gets up there, he's kept pretty busy. Anyway, it wouldn't hurt to walk in there with your old part and see if he has one for a decent price. Worst case, you can always leave if his price is out of your ball park. The advice of possibly getting one that has a higher voltage rating is good.
At least you could get your AC working today instead of waiting on the replacement. (FYI: All shops set their prices different, but my local guy is pretty reasonable if he doesn't have to install it)

Replaced ones on my house, my fiance's old house, and my fiance's new house all with cheapo ones off Amazon that came the next day. All less that $20. All working perfectly.

All set then. And, you got your hot and cold.

Thanks for the thought. Didn't turn up any good leads on that front, unfortunately. Should show up pretty soon. And I've got a big fan in the bedroom to tide more over, meantime.

That's encouraging.

May I suggest buying two capacitors? I mount the extra capacitor nearby so the leads can be switched when there's a failure. Local shop charged me $50 for a replacement one hot day. The very same capacitor was about $12 on ebay, including shipping.

Interesting idea. This old unit does not warrant the outlay for two capacitors. But on the next one, I just may do that.
