SOURCE: RV ROOF TOP AIR CONDITIONER TRIPS BREAKER

Possible low voltage condition would cause that kind of a problem. To small a cord without the ability to carry and maintain the voltage would cause a voltage drop. I would test the voltage supply and make sure it is within 10% of that required for your A/C to operate properly.

The compressor motor , once warm is grounding out due to wear and is going bad.Have the compressor replace while it is still clean is cheeper and easier that doing it after a burn out,which  will eventually happen,if the compressor is tripping the brreaker as I suspect..

SOURCE: dometic rv air conditioner over 100 deg. trips breaker.

The problem is that when u add up the electrical draw from all of these appliances running full bore, your draw exceeds your available amperage. Now you are doing the math and saying no...... Let me tell you why. It is rare to find a situation where a 100 amp service actually porovides 100 amps. You almost always have voltage dropo. And when you are adding extension cords to the mix the drop is even more. That said, When you are using the AC try to minimize the use of other appliances, especially the microwave which is a big draw too.

I'm betting it has something to do with the shift lock actuator or the harness to the actuator. I'm pretty sure it is located on the top of the steering column on your vehicle. The lower part of the dash will need to be removed and then the steering column lowered in order to gain access to it.

This vehicle does have an airbag and unless you experience with airbag systems I would not recommend tackling this yourself.

unplug the interlock. Replace the fuse. Start the vehicle. with your foot on the brake manually release the interlock with you hand and shift through the gears. If the fuse does not blow your on the right track. If the fuse does blow let me know and I'll get you some more info.

Let me know if you have any questions and thank you for using Fixya.com

I have a Ruud air-conditioner/heat pump and it blows 5 amp fuse.


It sounds like the thermostat wire going to the condenser is ground, It either got pulled loose and is touching the housing or as in most cases the wire got cut or was chewed by an animal. You need to turn electric off to both devices and physically inspect the thermostat wire going from the air handler to the outside unit, also inspect where they connect inside the unit. When you find the break, cut and strip each individual wire and securely wire nut each conducter red to red white to white and so on. There you go all fixed. That's when I give you the bill for $75...except this time you write that check to yourself. Good Luck

If your blowing fuses then you have something grounded or shorted. By grounded I mean a wire has come loose and is touching the cabinet or a part that allows it to go to ground or your motor, capcitor or compressor is shorted.
