what value of cap you need?? ...probably rated 270 Volts?

It's a specialty cap, made specifically for AC Units.

It's called Dual Run because is actually powers
both the fan motor and the compressor.

It's a 370VAC  40Mfd cap.

Don't worry about it...  I'm saving $20+/day by not cooling the house !

Curious Steph.   Did you get the part and did you fix it?   Did you really save over $300 doing it yourself?

Yup, yup and yup...

I found the part on-line for $17US,
but it was going to take 1 week to ship.
I ordered it anyways, in case I could not find anything locally.

I then spent that week-end looking for the part locally, and
basically got the run around.

On the Monday, I called every AC shop in Ottawa,
and half didn't even know what the hell I was talking about.

The last AC guy I called, told me to call a small motor /electrical shop.

I called a few (..who also had no clue what I was talking about ),
but one guy was very helpful...
he told me "... well, we don't have any "dual" cap, but why don't you wire two caps together...? "

" .. I can do that ??? "

" Sure, plug the compressor to a 40MFD cap and the fan to a 5MFD cap
and ground them together... "


It was ugly, but it worked  (...see the pic of the original [busted] cap, and the replacement "hybrid" ).

So I got the AC running on the Monday,
which turned out to be the last day of summer.

The weather dropped 15C the next day, and the leaves started falling.

So I apologize to everyone for cutting summer short by fixing my AC myself,
but it was worth $300 !

[ BTW:  I did get the eBay replacement cap a few days later,
but didn't need it by then...     ]

Good going!!  had the same problem with my milling machine motor blowing a cap.
was on the weekend and had to finish a part asap
looks like it was wired by the same guy    
did you watch Mcgiver too??  

Nice job Steph.   I guess the $300 savings went to the Chexx and vid games  

I just blew $216 on getting the rubber gasket on the freezer replaced.   Couldn't believe that was it.   I surfed the usual causes and most were talking about more complete board / compressor issues.   $216 is peanuts compared to you - as that covered 2 visits to the house and the $100 "gasket"...
