eBay ClickyThe model ending in "6" seems to target the SUPCO SPP6 and yes at a better price. Talk about spelling, what's a "Hart" start kit? The description includes a PTC device then later mentions a Relay. Aren't those mutually exclusive? SPP6e replaces a hard start cap + relay setup, while SPP6 is PTC.
My take - SPP6 knockoff at a better price. Attractive with free shipping. Only problem we've had with our Coleman Mach roof A/C has been the Blower Motor itself. But at home we've had several capacitor failures, both Compressor and Outdoor Fan. I got a spare cap for home (which doesn't use any kind of start device) and while I was at it, I got a spare cap for the Coleman and a spare start kit SPP6e.
A note, I don't know if an appliance parts shop guy was "puffing" his own goods, but he thought the SUPCO kit wasn't a long-lived product. Preferred what he had but wasn't there to sell when my daughter's refrigerator-freezer was down. It's been working OK since 2009 though. Still, I brought a failed house A/C capacitor to an appliance parts shop to match up a replacement. Sales person said, well, the one you had was rated to run only about a year. This one is rated for "much more service" (which I say because she quoted the service life and I forgot. So there's probably a quality difference in these parts.
Every on was Made in China, of course.
