|The Carrier central AC in my parent's home is ~17 years old, and I want to change the motor capacitor as a preventative measure. When removing the cover, I discovered there were 2 capacitors installed, as follows:
5uF @ 370Vac and 5uF/45uF @ 370Vac
The dual-cap had nothing connected to the 5uF tab, and the small cap doesn't appear to be 'factory' - it's laying down on the chassis (not affixed with a clamp), and has some black electrical tape wrapped around the tabs to insulate the connectors. I suspect the 5uF portion of the dual cap went bad at some point, and whomever serviced it didn't have a dual cap available so used a 2nd cap because it was handy.
I would like to remove the small individual fan cap and replace the dual cap, but want to ensure I wire it correctly. The schematic on the cover is old and is not readily readable. Here's the current connection.
5uF cap has 1 brown wire, and 1 brown wire with a white tracer. The cap has no markings on it.
5uF/45uF cap has 1 yellow wire (C) and 1 Blue wire (Herm). Again, nothing is connected to the Fan tab.
How do I connect this back up using only a dual-cap? Thanks in advance for helping a Novice!
