Ok, I've been out of the DIY arena for a while so I need some help.
I've replaced the condenser fan motor on a residential HVAC unit and the new motor uses a 7.5 µF run capacitor just like this one:
The replacement motor only has three wires: (AS DID THE ORIGINAL)
Black - I assume goes to the power on the circuit board (like the old one)
Brown -
Orange -
The old setup used a start/run capacitor rated at 40/5µF (the three terminal cylinder type) which powered both the fan and compressor motors. I know I can't just use this for the new motor as it is rated for 7.5µF.
So, here are the questions:
1. Do I just add the new 7.5µf run capacitor? And how should it be wired up?
OR...
2. Do I buy a new start/run capacitor (three terminal cylinder type) rated at 40/7.5µF? Will the higher µF rating damage the compressor motor? ...since the original is 5µF
Please advise.....it's hot.
Also, sorry for the misspelled title.....Capascitor?
