That "should be" a RUN Capacitor -------Its not the Part Number that is important..... its the 15 uF and the 370v spec.

They have several 'run capacitors', check the specs. A higher voltage is better as well as higher 'max operating temperature' ( 85*C is typical). It's what will PHYSICALLY fit is kinda important.
Also buy more than ONE !! Shipping is same and always have a spare,that you won't need is way better than needing one Saturday night at 2AM...
https://www.grainger.ca/en/product/CAPACITOR-189-227MFD/p/WWG2MDR5 is a 'run one, 200MFD'.....

START Capacitor...... you may want to try one RATED at 250V instead of 125 v.... should get longer life..

Thanks fellas. Definitely going to buy more than 1. I need 3 as we speak and have 36 exhaust fans on the farm so I'll probably buy 3 to start then after I'm sure they'll work I'll probably buy 10 at a time

dang 36 fans ! See where the 'qty discount' point is ! I used to buy computer parts in Quebec cheaper than here in Ontario and that's after shipping / taxes were added.
Also keep track WHICH fans are failing. Is it random or always 'the four on the south west wall' ?If the former..probably life of the parts, if latter, an 'environmental' issue ?

Are these motors able be to oiled? If so, there is special ‘electric motor’ oil that should be used. Not just run of the mill motor oil, or 3-in-1 oil.

I tried to follow the science, but it was not there. I then followed the money, and that’s where I found the science.

I won't say no they can't be but I've never seen an oil cup or hole that says oil or anything like that

Capacitor specs:
Run capacitor C107558440048
15.0uF 370VAC/B 50/60Hz
I searched for this number and it didn't come up. Got a close number but the last 4 digits were wrong
Start capacitor C103237310113
189-227uF 125VAC 60Hz
Found several matches with this number in different sizes. I'll measure mine and see which one fits. I think I've got the start/run thing right. Seems kinda strange to me that the run capacitor has a higher voltage rating than the start capacity though

The run capacitor operates at a higher applied voltage, for a longer period of time, than a start capacitor.
For the RUN capacitor, Johnstone Supply catalog pg 138 shows thier G35-270 as Titan part POCV15A Motor Run Capacitor, oval shape, 15MFD, 440v, height 2.75" width 2.75, depth 1.75" for $11.00
They list the same capacity 15MFD 440vac diam 1.75 height 3.25" in round form factor pg 140, G35-383, part PCRF15A, also $11.00
If your motor's failed capacitor is a Motor START cap, then replacing it wht a Motor Run will be death knell for it- they can NOT be interchanged of purpose.

life of motors..quality of air... been thinking about the 'hen house hell' and have a suggestion Instead of running 2 fans for 30 seconds each, run ONE fan for a minute. The combined volume of air moved is the same BUT each motor doesn't get 'short cycled' and destroyed. You said 36 fans, so if in one loooooog building, wire them up 'odds and evens'. #s 1,3,5,7,35 come on together then 2,4,6,36. That would be a better air moving pattern and distribute the 'wear and tear' on the motors and fan units evenly. I know you'll have to adjust for ammonia,but the idea is to have fewer fans on longer. It'll meet the guv regs(CFM/pound/hr ? ) and should save on repairs.
I did a similar setup for a bank with all electric heat and AC. Only two HVAC came on for 5 minutes. The pattern was 1,2 then 2,3 then 3,4 then 5,6 then 6,1. Loop repeats. was my first PLC program. Saved the bank 10K a month,so they were happy.

We do something slightly similar to that. Each house has 4 exhaust fans. 1 fan in the front wall, 1 in the back wall, 2 on one side wall. While the chicks are young and we can run only 3 fans, we rotate the 2 side fans each cycle. While we're brooding, we have to run the end fans every cycle because we're a center brood house. We use petitions and curtains to shut off the front 25% and the back 25%. We have to run the end fans to keep air flow the same inside and outside of the brood area. I've had instances where we had a fan on the end quit while we were brooding and when we're pulling more air in the center and less on the ends the curtain will pull the petition over and the birds wind up going to the ends before they're ready. Doesn't happen often but when it does it's about like chasing greased pigs.
We also run "stir" fans. They are 18" fans mounted in the peak of the ceiling. When the exhaust fans shut off these fans run until the exhaust fans come on again. The air constantly moving inside the house keeps the litter almost too dry.
We could try running 1,2,3 then 2,3,4 then 3,4,1 then 4,1,2 after we "whole house", meaning after we take up the petition and let them have the ends. Don't know what the integrator will think but might try it and see.
Going back to the variable speed fans, the problem we run into is the integrators really like to listen to certain professors at certain universities that do research for the poultry industry. Now when you're doing research you want to prove your results. When you plug a variable speed fan into your research, you introduce a massive variable and it makes the results harder to replicate. From what I've been told, this is the reason why "research" shows we're better using standard 1725rpm motors instead of variable speed. It's BS but that's what I've been told. There are integrators that will allow and some even promote variable speed but ours isn't one of them
