You don’t want to use a round cap in an oval mount or vice versa. Looks like USA2034 would work. | |||

They call that price gouging here. After a particularly bad hurricane it is against the law to raise prices. Before that happened all kinds of price gouging went on. I remember the local Otasco store selling chain saws and other supplies for triple the usual price. Word got around and they were out of business within a year. I would never do business with an AC firm like that. Do you realize that he thinks you are stupid? | |||

Thanks! I can't find a USA2034, including on AMRAD website. They don't seem to offer an oval can 15uf capacitor. https://amradmanufacturing.com...otor-run-capacitors/ Would the specs on the USA2209 work for me? Is there a functional concern with a round vs oval can? Or just mechanical stability in the mount? "Wrong does not cease to be wrong because the majority share in it."

Can I order a spare just knowing the make, model & serial number of the AC Unit ? Or do I need to pull the cover and CAREFULLY look at the existing Capacitor ? Thank you. | |||

Typically, the manufacture data plate/sheet does not provide the value for capacitors. There are some sites that you can search that have the correct values for capacitors for quite a few units, but it takes some digging. Identified by compressor make/model, as well as fan make/model. You need to check the one you have, but realize some techs will stick what they have on their truck to clear the ticket. (shameful as that is). If you find a good HVAC tech that is trustworthy, get their name and request they do your service, or call them directly if they have moved on to another company.

Thank you.[/QUOTE] I’d do both, never know if someone threw in a different one in a pinch. I’ve used Capcom brand ones in the past, “assembled” in Mexico. Can’t say I’ve had any issues.

It’s mechanical stability. I tried an oval one once because it’s what they had in stock. I rigged that seemed sturdy enough at the time, but 4 months later it slipped and shorted against the mounting strap. Fortunately, no permanent damage. As far as specs, you have to use the correct capacitance, the uf rating. I once read why and it made sense at the time, but I cannot remember much. Something about the motor’s windings, phase something, rotational magnetic field, I don’t know. Whatever it was, it wasn’t a case where a bigger one could be substituted. The VAC is a different story. You can use a cap rated for 440VAC instead of one rated for 370VAC, but not the other way around. I don’t know about the tolerances. I suspect the difference between +10% -5% and +6% -6% wouldn’t matter. I would get whatever USA made brand I could. I’ve never needed to replace a cap for the blower motor. I have done at least 5 for compressors, 2 contactors, and 1 breaker. | |||

Yes, and that provides better margin of reliability as the higher 440V rating cap can withstand any surge in voltage without damage (in a lower voltage system), but the microfarad rating has to be the same.

I believe code requires a disconnect switch at the AC unit outside . | |||

Older houses may or may not have a local disconnect, certainly modern construction will have a non-fused disconnect within sight of the unit. __________________________________ NRA Benefactor I lost all my weapons in a boating, umm, accident. http://www.aufamily.com/forums/ | |||

So I pulled the cover a took pictures of the Capacitor. Looking on the AmRad website they list one of the correct size (75/5) and it is close in physical size (height is within 1/2"), part number USA2222B. I can't find any manual for the unit a Tempstar (Carrier) N4A360AKN400. The house is about 4 years old, but I don't know if the previous owner ever had work done. So I'll ASSUME that the Capacitor that is installed is the correct size. Thanks again. | |||

Yes, Tempstar shows it as 440V 75+5 "the meaning of life, is to give life meaning" ✡ Ani Yehudi אני יהודי Le'olam lo shuv לעולם לא שוב! | |||

Thanks!! Good info to know. Very helpful. I have replaced both caps under duress (ie - it was during the high heat of summer) so it was cheap parts. I think the condenser twice and the blower once over the past 25 years. I aim to be ready with amrad parts the next time.  "Wrong does not cease to be wrong because the majority share in it."
