One of my cooler compressors is down...
I want to replace caps before calling the HVAC guy.
I found the run cap is 35 MFD
The start cap print was dim and dirty so I tried to rub the label. It came apart :(
The cap is 2 1/2" diameter, 4 1/4" high on a 2hp refrigeration compressor.
Very partial label: ???? TRAL AB ???? 4576BC8
What size cap should I try?

Mostly depends on the horsepower, or btuh, in your case.
Find the compressor model number, Tecumseh and Copeland both publish their cap sizes IIRC
Some info, mostly for Emerson by model number here:
Sorry, friend, don't know. 220 MFD is a wild guess.

Ummm... ONE of your coolers? Why not look in another one? Lloyd
Either they're another brand, or are in similar condition, or he forgot to think of that. Good catch.
well, I ordered a 300 from Mcmaster. we'll see what happens.
BTW, this is the only compressor like this on my place, couldn't look at another one.
Karl
That's a good place to start. I suspect it will work fine. Please let us all know how that works out.

And here I thought you were going to spin a boating yarn...
Compressor is running. I like cheap fixes.
Karl
You weren't kidding when you let us know. Good one!

I no longer have the old catalogs to see what it could have been. At least you got it working.
It's a little late now, if it was too much or too little something expensive will have broken by now - But...
Reading the old capacitor nameplate is irrelevant.
The compressor nameplate is usually stamped steel or something else equally indestructible, and most likely still legible - you can look up a data sheet on the compressor and it'll show the capacitor needed.
