I have train XB1000 central AC unit the condenser fan runs about 45 min and stops. I have changed the dual capacitor and same problem if I wait about 15 to thirty min turn back on it repeats same process. Should I replace the fan motor

Sounds like that would be the best ting to try.

Just to make sure, you are talking about the fan, not the compressor right? When fan shuts down, does compressor keep running? If so, then Josh nailed it, you most likely need a new fan motor.

One other thing to check, how dirty is your condensing coil. If it is plugged completely, it will overwork the fan motor and the compressor. Take a look and let us know what you find.

Yes the compressor is running and coil is clean the odd thing is thou the last time I started it it ran about 5hr. And now back to same thing... does the fan motor have an internal trip

Yes it has a inturnal overload what is probably what is cutting you out.

Thanks will try and find fan motor and replace

OK I like to thank everyone for there help and mygirlsdad77 you were right went out side and took panel off to get full access to coil it was dirty I power washed and everything is working great did not have to change fan motor I can't thank you guys enough!!

Glad to help. I hope it keeps working for you. If it does fail again, replace the motor and you should be all set. Make sure to check the outdoor coil at least once a year.

Great advice I already order motor just in case lol thanks
