Condenser fan dual rated capacitor

I have been looking for a replacement capacitor for my Condenser fan. It has a dual rated 7.5 / 45 MFD 370 volt. I have found a 7.5 / 50 MFD 370 volt. Will it work? I do not want to damage the compressor, so I am looking for some knowledge! Anyone got an answer? Thanks![FONT=]undefined[/FONT]

A capacitor that is too large will pass too much current to the start winding and overheat it.

If you can't find an exact replacement you can use separate capacitors.
A 7.5@370 and a 45@370 would do it.
Just use a jumper between each of the capacitors where the power wire is connected, connect the 7.5 to the fan and the 45 to the compressor.

Thumbs up condenser fan capacitor

Thanks for the reply. Thats just what I am going to try. I spent most of this morning trying to find the correct replacement, and finally decided to go with the seperate ones. I will proceed with a little more confidence now that I have read your post.

In the future remember that you can "over size 10% on the capacitor with no ill effects.
