The dual capacitor for the condenser fan and compressor needs to be replaced. The specs on the capacitor from EUN SUNG IND shows 45/12 uF 370 VAC.
The specs on my non-heatpump unit is from GE and shows 12/50 uF 330VAC. The part number in the Carrier manual identify the condenser for both units as
a 10-50061-00.

Am I correct to believe that the 12 uF is for the fan and the 45 and 50 are for the compressor? I have not been able to locate direct replacements for
either of these. I know just enough about this stuff to be dangerous.

So I have a few questions: Can I use either a 370V or 440V capacitor for replacement? From what I have read this substitution is OK. Now the second
part. Can 2 capacitors be used? Like one for the fan of say a 12.5 uF 440V and 45 uF 440V or 50 uF 440V for the compressor? ie is it ok to go up a
little in the MFD?

More than likely the smaller capacitor (12uf) is for the fan and the larger one is for the compressor. But I would try to verify that with a wiring
diagram if one is available. Any voltage rating above 370v is fine. You can use separate capacitors just make sure that you observe the polarity
marking on them. But with all that said, I think this will work for you.

I have heard of a hard start capacitor for compressors. Is it advisable to use one when a new capacitor is needed?

Rick, thanks. The parts house told me I could use a 45 10 uF 370V or 440V. They just would not sell to me. While most retailers complain that people
are taking their business to the internet, these guys are encouraging it. Go figure. Is there a down side to using a lower value on the fan? My
capacitor is bulging, the compressor starts and runs fine. The symptoms showed up on the condenser fan.

I have not researched the hard start systems such as the Supco SPP6E so I know little about them.

John

The 10uf is slightly below recommended. These caps have about a 6% tolerance so a 10uf would range from 9.4 to 10.6 uf. A 12uf could be as low as
11.28 so they are close. A slightly lower capacitance results in slightly greater motor winding current. Too much current can be detrimental but this
is a small amount. It is nice to match exactly but again this will probably be ok. You can always parallel capacitors to add to 12uf. The bulging of
your cap is a definite failure.

McMaster Carr is a good source for capacitors -- the last I bought were GE.
And since you live in a large metro area you could probably have them by Tuesday latest,

The HVAC wholesalers around here are like that also but I have been successful in just talking my way around that. The one I use most often I first
bought from them was when I was 14 years old. I needed a motor start capacitor and some had to drive me over there. I bought it then and have bought
many things like a complete furnace with AC, furnace mounted humidifiers, electronic air cleaners, and the list goes on and on. Most recently I
bought a new fan motor about 2 weeks ago from a place I have never used before. I just talked my way through it. If you have any friends in the
maintenance department for any buildings like a hospital, etc, have them get it for you.

My last receipt says sold to: Contractor, cash sale.

Pardon my French, but at that point, I would tell them to go fuck themselves. Yes, they are driving the business to amazon, the walmart of the
internet, and by "protecting" their market, they are only hastening their demise. Kudos to you for trying to buy local, but these guys can take a
flying fuck. Sorry, I feel that strongly about it. It is not illegal for us to buy R410a but Johnstone supply lies and says you have to have a permit.
The counter guys will sometimes tell you the truth, as it is company policy not to sell to the public. So, I pay $100 for a 25# tank on amazon instead
of $50 where they will make $25. Fuck 'em. Hope they all go out of business since all they carry is shitty Chinese "haier" branded stuff anyway.

Now,

Most large cities have a place that sells to the public with their middle finger to the industry that charges extortion prices for poorly made crap
and shitty "technicians" who cannot troubleshoot their way out of a paper bag. We have one in Mesa, AZ. Very friendly, very helpful, They just don't
sell refrigerant. Prices are fair.

Hope you find the local guy in your area and send him the business he deserves.

/rant off.

FYI, you can use separate caps for each motor, dual caps are just a way to make the systems cheaper to manufacture for more profit, but more expensive
to service. See, there's that shitty HVAC industry working against the customer again...
