I installed a new condenser fan motor and capacitor but after an hour of working the fan tuned off,checked the voltage, and amps to motor everything read fine.compressor kept on running so I shut off.I don't know what else to look for this is the first time iv'e seen this problem happen. I installed a 1/4 hp 208-230v motor.

It is possible that you connected the wires wrong. Did the capacitor you replaced work only for the fan motor or was it a dual capacitor for the fan and the compressor?

The capacitor that I replaced was only for fan motor. I'm sure its wired correctly there was only four wires frm motor, blk and what wich I connected to contactor,brwn and brwn with what line connected to capacitor.

I rinally figured it out. I called the manufacture and they told me that even though the unit said it needed a 1/4 hp fan motor I needed to replace it with a 1/3 hp.So I did and it worked fine . Who would have known.Thanks
