It's on a Fedders condensing unit which also I've never seen before. What the heck is it? It's tied from one end of it to the other and to the herm and common on the capacitor.

We talking about the same thing? I'm talking about the little small gray can that's above everything else. Makes sense it'd be a start cap of sorts but why an extra one? It's not a super start cap is it, like a hard start?

Btw that was not the issue, the regular dual run cap was blown.

The correct name is Thermister Starter Kit. We need to know how test it.

Beats me. All I know is once I replaced the dual run cap the fan didn't start. Then I unhooked that thing completely and it all worked. I thought that something wasn't right as that was only hooked to the comrpessor, checked all terminals and realized the fan spade was loose and not contacting properly on the dual run so I removed that wire, bit down a bit on the spade with my Kleins to tighten it's grip, re-installed that thingamajig and everything worked so I left it online. Turned the system on and off, on and off and it was all good.

Would you mind explaining further? I've never heard of a soft start and I haven't a clue as to what PTCR stands for.

Thanks, Obie One.

p.s.-I had a Carrier 410-A 5 ton that I cleaned the coil on today and once I replaced and re-installed the lid/fan the flash code at the condenser control board was 72, thermal cutout. Huh?
I removed the 24 volts to said board in condenser for about one minute and sure enough it reset and came on.

yeah me.
