Air conditioner problem and FIX!
Hello, all. I just fixed a problem with my air conditioner that I thought would be a good thing to post about. My air conditioner worked when we first got the coach, but on our second outing, it s...

That strap on ours is only "snug." I had the Fan Cap out recently and didn't even have to loosen the screw. You're right, Jose, the failed caps usually swell and/or push what's left of their fluid out of a relief port.
Some Coleman units don't have the black start cap and associated relay or PTCR device. Should start (given a good power source) without those two, if the compressor run cap is good. But I'd guess (and this is only a guess) that failed start cap and/or relay might prevent an unassisted start unless disconnected.
Oddly, our home unit (4-ton central) has only run caps, no start assist. When its compressor run cap fails (and it often does, I keep a spare!), the compressor will not start, and it goes to the Locked Rotor Amps value on its rating plate. Doesn't stay there long enough to trip the breaker, though. The cutoffs on the compressor open up and then it tries again in a few minutes.
The two run caps (didn't look at the start cap) have an mfd rating and a voltage rating. Coleman says 370VAC.
You can use the common 440VAC rating, or the increasingly common 370/440 rating. Can also replace a 440 with the 370/440. Just not a 440 or 370/440 with one that's marked with only 370.
There are also durability ratings that I don't know how to read yet. Some are good for like a year's service and others for much longer. From what I've seen so far the durability isn't always reflected in the price. I just paid much less for a high-rated one than I paid awhile ago for a low-rated one at a different appliance parts store.
