I don't very much about capacitors but I have a supplier that insists that a 40 mfd 370 VAC rated running capacitor can adequately replace a 40 mfd 450 VAC rated one. Based on what I read, a starting capacitor can vary by up to 10% but that running capacitors must be matched perfectly.

I am replacing my 3 wire condenser fan with a universal that has 4 wires 1 black 1 white 1 brn/white stripe 1 brn I bought a new dual capacitor at the same time so my question is where do the 2 brown wires go on the dual cap? The old one had one brown wire.

The dual run cap on my central a/c condensing unit went bad (had a hole in the side of it, leaking). It was a 35/3 mfd 370v dual run. I ordered one on eBay http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=150483022031&ssPageName=STRK:MEWNX:IT, and I have installed it. The contacter is working,...

We have a Rheem Heat Pump that apparently has either a bad (outside) fan motor capacitor or a bad fan motor. I was going to replace the capacitor, but can't locate it.

I have replaced my motor on my outdoor unit but can't remember how the wiring goes back to dual capacitor, I have three wires, brown with red mark, red and white. Which goes to common and fan and which terminal does the other wire go to?
