    Truck Stock - Start Capacitors / Start Kits

    I haven't really found anything specific regarding the subject of stocking start components for 1.5 - 5 ton split systems. I have many run capacitors and though start component failures aren't as common I'd like to have some components on hand. It seems that Trane is pretty finicky about OEM start components but are there some pretty common start cap and relay combinations that should be kept on hand or is the more practical route the universal start kits, if so which ones?

    We don’t stock any start caps. We stock a hard start cap that I use to get them by until the right start cap can be ordered.

    If the ONLY thing you work on is as you stated (1.5 - 5T) AC ,then you might get by w/ the 5-2-1 relay/start cap kit'S or the Supco SPPE kit'S. The 5-2-1 kits ,which there are 3 all have 3 diff strength st caps. So why are there 3 diff size st caps? Even the Supco SPP(E) series of which there are 7 diff sizes use the 3 diff SPPE sizes to match up to the three 5-2-1 kits. The 3 "fairly" common st caps in those kits are 88-108 mfd,189-227 mfd & 270-374 mfd. Chose carefully and wisely. BUT, I suggest that you start a list of what the compressor maker ACTUALLY calls for and see for yourself that you are doing the right thing for the customers comp and your reputation.

    Along with a variety of run caps, I just stock a couple of hard starts. Usually works until I can get the CD right start cap.

    I have around 20 diff Copeland start caps on-board as I do AC&R, and I like OEM exact parts.

    So you don't like that How about this
    2.5, 5, 6, 7, 8, 9, 10, 12, 15, 20, 25, 30, 40, 50, 60, 70, 80, 90 & 100

    All 440 volt
    Now there are several micro caps but well save those for a later date.

    pay attention to the caps you come across and write them down.

    Get a couple to carry ... along with a supco "SUPR" Relay

    That relay is universal and will buy you plenty of time until you replace it with OEM

    I still have a couple out there waiting on OEM

    Thanks for the reply but I believe you have misunderstood my inquiry. The subject is starting components not run capacitors.

    Isn't a Run cap a Starting Component?

    That's pretty much all you'll have on a small unit like that!

    I have all 3 of the 5-2-1 Compressor Savors (see attachments).

    I use the one that most closely matches the manufactures specs for the Start Cap MFD rating, and Potential Relay specs (pick up, drop out and continuous voltage).

    On Trane units, I only use their OEM start cap and relay.
