There was not an A/C installed in the trailer when we bought it. I bought a new carrier 15,000 BTU low profile unit and had it installed. I camped for two days after installation to test everything, and it all worked. It is when I brought it back home that it started acting goofy. I do have the trailer plugged into shore power, but my house still has only 20 amp circuits with old screw-in type fuses. It is also connected with a small guage 50' extension cord.
Plugged in a lamp to the fridge outlet with AS connected to shore power, and it has power - lamp comes on.
I am working today, so I am relaying info back and forth to my wife, who is trying various methods. She did try and plug the A/C directly into the extension cord running to the house, then turn on A/C fan only and it came on.
But the A/C is wired to a standard plug and plugged in with the fridge. Can this circuit handle this load? Is this the proper way to wire a new A/C? (I didn't have any problems when connected to 30 amp hookup at the campground).
She tried the same thing with the fridge (plug directly into house extension cord), and she did not hear it come on and start running.
I will definitely look at the new lights for the 12V side of things.
Could it be that my house circuit/cord is too small to handle the A/C current draw? This doesn't explain the fridge though...
