AC / Supco assistance needed

Ok, I checked this weekend and I only have the Supco Spp6, not the -e : so I put the stock unit back in for now as it seems to work comparably.

The model number is 49201A876; I'll try to post a picture of the model sticker ASAP. I'm still interested whether the spp6e would be an improvement with a small generator.

Thank you all for the advice!

The FACTORY start cap is matched to your compressor the aftermarket is not it's a one size fits all. Its not broke so why to try to fix it. I made my living in the refrigeration business.

Either SUPCO, SPP6 or SPP6e, will connect the same ways. Two black wires replacing whatever the OEM start assist had. Probably Red and Yellow, with PTCR inserted in one of them. Unless part of your OEM start assist is bad (PTCR and/or the capacitor itself), SPP6 is another PTCR unit and will be little or no improvement. SPP6e has some intelligence to it.

Thank you J-D! The supco I have I believe is the 'e' version, it's the 2 wire. I'll double check tonight on which one it is.

YES. The OEM Start Assist Capacitor AND the associated PTCR device BOTH need to be removed. If you were installing a SUPCO SPP6 (no "e") it has its own PTCR built in and you need only the one built into the SUPCO unit.
The SUPCO SPP6e (E-Class) has a built in electronic device that approximates a Potential Relay, and that's all you need with it. Another PTCR would only interfere with either SUPCO device.

Chris (or anyone else), I did install the Supco in place of the stock unit and it seems to work identically. However, I'm wondering if the PTCR should have been removed when I installed this?

Any clarification any of you can give would be greatly appreciated!

chris,

Thank you for the quick response - replacing the stock with the supco should be easy enough. The black capacitor is the starting cap, correct? What is the 'PTCR' inline with the starting cap? Should this go inline with the supco as well?

This is a 9000 BTU coleman unit. I'm not sure what the model is as my paperwork doesn't say - but it says 'low profile 9000k btu' in the build sheet for the trailer. Had I bought the trailer new I likely would have opted for the 13.5k, but I didn't. Ironically, the 9k costs more than the 13.5!

I have noticed the AC will not attempt to restart when it is shut off for a few minutes - assuming this is the effect from the high pressure switch?

I guess the good news is this should run on my Honda 2000 if the converter isn't in boost mode, so maybe I don't need the twins anymore!

You do have a start kit installed, which is the equivalent of the Supco SPP6. In my opinion, the SPP6E would be better with a genset than the stock part. You would replace the existing kit.
What model is that? I haven't seen a high pressure switch in one before.
