AC Capacitor Question
Posted on 9/7/20 at 11:16 am
Posted on 9/7/20 at 11:16 am
I have what I’m pretty sure is a bad capacitor on one of my AC units. I’ll hear it “kick on” but the fan won’t spin. When I spin the fan manually, it spins as it should. What are the important bits of info do I need from the label?
I see
35/5 +- 6%
440ac
50/60Hz
HC98KA036
CBB65B
I guess I can just bring it to a parts store but I would like to see about ordering it off Amazon. I’ve done a few searches and all the ones I find won’t be delivered until Thursday at the earliest.
Appreciate any help, I’ll probably just bring it tomorrow when I go to parts place, can’t go wrong that way I guess.
I’ll be sure to remove power from the unit and discharge any residual power in the capacitor before removing it.

Sounds like the capacitor.
Turn off the unit at the thermostat too.
May want to get a spare when you go in.

You need the volts (440) and the microfarad rating (uf), afaik.
I wouldn't wait to order online, they are pretty cheap at stores.

You have a bad fan motor

You just need these 2 readings off the capacitor, 35/5 and 440 ac when purchasing a replacement, but it’s good if you can bring it and get the same diameter and length capacitor just so it will fit in the allotted space.
If you have a multimeter with a capacitance/microFarad (uF) setting you can check if it’s bad yourself.
The American made AmRad capacitors, with 5 year warranty, are better than the cheaper Chinese capacitors if you have a choice, from where you purchase it

Good suggestion on American made caps.
MARS is another good brand.

Buy a spare capacitor while you’re at it.
They seem to fail on weekends and holidays

Where local are these sold to the public?
Just paid to have mine changed 3 weeks ago and was going to order a spare online.

I got mine at Ideal Appliance Parts on Florida Blvd in BR earlier this year.

35/5 440ac
these are the only numbers that mater
35uf is the compressor side
5uf is the fan motor side
440ac is the max voltage it can handle
you can just get an wire up a 5uf/440ac run capacitor to get the fan working in an emergency but if one have went bad the other will fail shortly as well

Any electrical supply shop or appliance store should stock some, and home depot and lowes might even carry a few. I would just call around.
If you're just ordering to have a spare on hand, then I would go ahead and buy online though. I just suggested that OP find one local so he wouldn't be without AC until Thursday. The difference in price is negligible, and might even be cheaper locally for a better quality part. You just save a trip to the store buying online.
In the last two months, I have changed the cap for the condenser fan in one unit and the cap for the air handler in another unit. Both units are 25-30 years old. My local electrical supply shop had both caps in stock for around $10-12 each, and this is a small town. One was the wrong shape so it didn't fit the strap that held the old one, but as long as you secure it so that it doesn't move and the terminals can't arc onto anything, you'll be good. I like to wrap each connection individually with electrical tape. I also like to tape up wire nuts when I change light fixtures and such, even though they were never taped to begin with in the (admittedly older) houses I've done this in.
They are really easy to change, but I would recommend watching a YouTube video if you've never done anything like this before. Specifically you need to make sure that you pull the disconnect first and that you've discharged the cap so it doesn't pop you. It probably won't kill you, but it'll scare the shite out of you.

Try Coburns. They sell a/c parts not in contact with refrigerant to the general public.

How is this performed?

Should be a disconnect on the wall near the unit. Open the cover, grab the pull handle and pull it out.
As for discharging the capacitor, it's probably not proper but I believe most people just short the terminals a few times with a screwdriver. Wear gloves to be safe I guess.

I have literally zero input to OP, but I wish I had friends like you guys locally You can answer just about anything.

Tinfo! I was under the impression that the general public could not purchase these for some reason so I never inquired until seeing this thread.
Amazon has the one I need for around $22. But for something like this I dont mind driving to a local supply to purchase.

You can get them at Grainger Industrial Supply as well.
Go to their website to find the closest
