Air cond will run for 1-1.5 min then stop , will restart after about 2-2.5 min

going out on safety. drawing to many amps or overheating.

Have you tried here? ( http://www.rvcomfort.com/rvp/tech_info/manuals.php )

Try a new fan motor. It runs about $125.00, It will run a few min. then will trip the motor themal switch. you can probably still here the compressor running. It may also trip the breaker on shore power . good luck! the part you are looking for is a 1/3 hp 115vac 2 speed 1580/1020 rpm part number #1468-3069

Pull filter off at ceiling and look in at coils and see if all frosted up, and let me know what you find. Check when it shuts down.

The only thing that is going to but the fan off is the thermostat. When the fan stops, immediately check the thermostat on the wall. See is there is power between the B terminal and the GH terminal. If none, then replace the thermostat. If there is, then replace the control board in the AC. That means that the fan relay on the printed circuit board is weak.

ring jayco for a tech to come and fix it for you.sounds like a short in the unit some were.

The fan motor is getting hot and going off on the internal overload in the motor.
This is caused by either a low voltage, a bad capacitor, or tight or dry bearings in the motor.
To check the bearings turn the power off to the unit, then spin the fan blade if it spins freely then the bearings are ok.
To check the capacitor you will need some kind of
tester or you can buy a capacitor and replace it, that's what a lot of people do. They usually don't cost very much.
To check the voltage you will need a voltmeter and measure the volts at the unit.

sounds like the unit is low on freon. it will need to be serviced so the leak can be fixed then recharged.

Start capacitor, fan motor or the compressor is worn out. Most times its start capacitor. Thanks, Sea Breeze
