I just had my TT a/c looked at by an rv place the guy went up to the roof and took the cover of the ac unit and took a grey in color part of the unit and told me that this was the capsor. and this is why my ac motorfor the ac does not turn on on its own. when I look at the part I seen some type of paste uzzing out of the part it was black in color.Can some one tell me if the ever heard of this? some times I dont trust some of this people. or maybe I am paranoid?

Start capacitors are known to basically melt when they go. I think he's telling you the truth. $25. part, plus labor...

Very common. An oozing capacitor is losing its electrolyte and therefore will not function correctly. It may even be shorted internally. Its probably a dual unit (3 terminals) with one section for the fan motor and the other for the compressor.

Sounds like he's telling you the truth, kenny. The part is probably much cheaper than the service call/labor.

And one more question How long are theis capacitors are supposed to last? thanks in advance to all that replied.....

It depends on what happens to them. If you stall the compressor (like turning the AC of and on again) it puts a huge load on them and will blow them after a few times.

If it's a 13.5K BTU replace it with a Supco 6E. That should last longer than the original.

I have some capacitors that are several decades old and still good and have seen others that fail within a year. I don't know why but like any electrical/electronic component there is a wide range. In electronics school we were taught that active components like transistors are the most common device to fail and capacitors are second most common to fail. Inductors and resistors being least likely to fail. Don't consider your situation a big deal or worry about a repetitive failure on this component.

A wide range of component quality, to be sure, and a wide range of environmental variables, too.

There's not that much difference in quality as there are a handfull of manufacturers that make them for different vendors. Environmental factors don't affect them either as they are sealed components, not does starting the compressor. That's what they are made to do. Longevity is luck of the draw. I have had to replace them when they were relatively new and I have customers with units that still have all of original components including the compressor.
