Duel run cap with no info.


Hi DIY. New guy with a problem.
I have a nordyne A/C compressor and the fan is not working.
The compressor does run.
After pulling the fuse I can spin the fan easily with no binding.
The duel run cap is very rusted and I can only identify C5C.
The common terminal is melted and loose.
The cover housing the the wires and board had a tag at one time but is now gone.
The unit is about 15 or 16 years old and has no readable info. on it nor does the compressor itself.
It is my understanding the volts can be different 370 or 440 but the
microfadaders connot.
How can I tell what duel run cap I have ?

Hi biggles. Thank you for the reply. I tried sanding with 800 but was ineffective.
Hi hvactech126. The electrical compartment had a sticker at one time. I can see the glue residue
but the sticker is gone.
I do have the fan motor info. and also found some compressor info.
Fan motor = emerson model KA55HXSMP-23473, 1/4 hp
volts= 208-230, HZ60, amp 1.7, ph1, rpm1075
compressor= copeland model CRG3-0250-PFV-270
serial# 93E30823A, LRA 75.8
If any of this is helpful I would greatly appeciate it.

you need a 35/5 mfd 440V capacitor

this should be your model number of your a/c : JS3BA-036KA
