50 + 15 is an odd one. Who makes the AC unit. I usually just replace them with a 35/5 at 370 volts and that is fine.

Duo Therm by Dometic.

It sounds like a bad capacitor. You can really only check if compressor is pulling too much with a clamp on amp meter. I would go and buy the cap for $15 to 20 bucks and try that. 

I need a 50+15 and have a local shop looking for one. I wasn't able to find one on amazon, Graingers. ebay,..  Was hoping I missed something on the board.

No I didn't. I rest my thermostat checked the lines in the unit to see if clean.. My wife said that when she turned it on earlier it sounded like it started hard. is there anything further I can check? I did checked the 3 amp fuse,good, didn't see loose wires either..

I have 2 rooftop duo-therm ac's with heat pumps. the living room ac was working fine then the compressor started shutting down and restarting for maybe 2 to 3 seconds each time and would cycle on and off. The fan stayed on throughout. It has been 90 with high humidity so I turned it off for the night. This morning when I tried to restart the ac it took about 2 - 2 1/2 minutes for the fan to come on (normal start) but again the compressor would try to start, I could here it bump on but shut back off, after a couple times of this I shut it off again waited a while and tried it again same results. I pulled the capacitor check it with an analog volt meter. it bounced to zero then back at each side, and it had no visual damage. Any Ideas??
