Anywhere to get a fan capacitor tomorrow?
Posted on 7/24/21 at 8:41 pm

Condenser fan running slow, going to assume it is the capacitor at this point. Haven't had time to look to see the model/ratings, but wondering if there is any chance of finding one somewhere tomorrow.
Any suggestions? NOLA area.
ETA: Looking at the fan specs I believe is will be a (35?)/5uf (microfarad) 360VAC

Amazon maybe. Otherwise you're SOL until Monday.

I don’t know enough by any means to say for certain, but I don’t think that’s how it works. Pretty sure capacitors either work or don’t, and this causes the fan to either work or not work.
If it’s slow, I’d think it’s more likely a problem with your fan motor.
What you can do though, or so ive been told, Is take a water hose and mist your outside unit constantly. So like a sprayer on very low. This will help to remove some of the heat to maybe allow your unit to work better.

I believe this is a run capacitor, which would allow it to kick on, but not come up to speed. Something how the capacitor works as the other phase or something. Hopefully some spark chaser jumps in to clear it up.
I am concerned about the fan and might purchase one for a spare if it isn't too bad. Looking at my a/c usuage it started on Thursday and I just caught it today. So I am concerned I overheated the motor and caused some damage that might not show until next week.

Most supply houses will do a call out for $100 on a Sunday but you would probably need an account.
I've learned to keep A/C capacitors and one relay on hand. Over the life of the unit you are guaranteed to replace all 3 in 10 years. (start cap/run cap/relay).
Many newer units have the start and run cap combined into one unit.

If you should find one on a Sunday, it will costalotium.

So....about your extras....
I see Lowes in Harahan has "limited supply" so I am hoping and praying on that one. Probably just one lost in the stock. Ordered a few high possibilites from Amazon to be delivered Monday.

What size do you need? My spares are dual run (start and run in one cap).
I do have a commercial account at Johntsone supply here in BR.
High likeliehood with these temps you may not have to pay for a callout as I bet people are needing parts with the high temps the last few days.
Post up your email if you want me to contact you and I can call Johnstone in the AM if you want.

ETA: Your asking about NOLA area but your sig says Prairieville so Dunno if BR is any help...

In NOLA. If it gets to the nut cutting I will try to get in touch. Have someone that can call in to Johnstone for me on Monday, but need to get my capacitor size for sure.
Probably don't have much of a chance of fixing it until Monday anyway with work, but was being hopeful.

Have you looked at your capacitor? Usually takes 3 minutes to find and they are usually visually bloated when bad

You can get parts on Sunday at Johnstone, but may have to pay a callout fee. Have your buddy call today, they may be in the office doing callouts for someone else and then you don't pay the fee.
As far as the cap goes. They can be swollen sometimes but not necessarily. You're giving two numbers in your OP which would be a dual run (large value is start cap, small value is run cap). You can also measure the capacitance with a DMM. Any supply house will stock it and most A/C guys will have one on their truck.
Good luck.

If you have to pay a $100 call out fee, may as well just pay the $200 and get an AC company out in case it’s not the Cap and move on with life.

Got it apart and it is a 40/5uf 370. Looks pretty decent. I know there are some tolerances that allow for a different cap, but I think I will just wait until tomorrow and go to Johnstone and get a fan motor as well incase it isn't the cap.
Managed to keep the house below 74 with window units so it ain't too bad.

Do you have a multimeter with a capacitance (micro Farads) function? If so, it’s very easy to check the capacitor to see if it’s within specs or bad - tons of YouTube videos by HVAC techs on this. If replacing, get a American made capacitor if possible - AmRad, Jard, Mars.
Your initial description of the problem does suggest it could be bad fan motor - maybe bushings in the motor are bad - fan motor might run, but often it squeals. A quick way to check if it’s bad bushings is if you can give the blade a good spin through the grill and it rotates freely - maybe 3 complete revolutions - bushing are likely good. If it stops rotating after a quarter, 1/2 a complete revolution then the bushing are likely bad and the motor needs to the replaced. Had to replace mine 1.5 years ago with this issue. If you need to replace the motor or get a spare, try to get a OEM motor and not a universal fan motor. All the wire colors will match, and a universal usually comes with an extra wire and colors of wire may not match the OEM. It’s an easy DYI project - I replaced mine.
If you have to replace the fan motor, change the old capacitor even it checks out as being good.

In addition to what CrawDude said, make sure the fan blade is placed on the shaft exactly as the old one was.
Otherwise, the air flow will not be proper. Measure the distance from the motor to the blade mount.
And don't get shocked!

Yes - this extremely important.

Thanks for all the info and pointers.
My goal is to not get shocked, not fall off the roof, and get the a/c repaired. Hopefully in that order.
I did realize one thing that I should probably somehow address. Last week I put a gable fan in the attic to try and remove some heat/humidity. Due to a lack or options, and roof design, the gable fan discharges hot attic air withing about 2' of the outside condenser unit. Probably not an ideal situation for cooling the condensing unit. Definitely not an ideal situation doing this job with a 1700cfm hair dryer pointed right at you.
