AC tripping breaker

[mattp160]

We just got back from our 2nd camping trip this year. On our first trip we had no AC issues. On this trip I noticed the AC would stop working throughout the day and night. I decided to check the breaker and it was tripped.
I flipped it back over and a few hours later, it tripped again.
We have a 2014 vibe 826vfk. We just purchased it this year so I plan on taking it back to the dealer this week.

I also noticed that the AC would hum very loud at night and almost vibrate the camper. Is this normal?

Looks like the trailer is still under warranty, I would not mess with anything and take it straight back to the dealer. You could lose your warranty if you tried to tinker.
It could be a bearing or something else causing an imbalance somewhere.
The good news is you know the breaker works .

If still under warranty take it back to dealership for inspection. But it could be that you had low voltage at the campsite, which would increase current draw and trip breaker if above rating.

Fronzie,
I thought the same thing, so I hooked the camper up to my 30amp connection outside my garage and after a few hours it tripped the breaker again. I'll be calling the dealer tomorrow to get an appointment setup.

When you mention that it trips the "breaker" is it the 15 amp air conditioning breaker or the 30 amp main breaker? If it's the 30 amp main breaker, you might have too much load on it at same time eg: air conditioning, water heater, refrigerator, converter...if it is the 15 amp air conditioning breaker and voltage is within tolerances, then your air conditioning or breaker needs to be look at.

I would (CAREFULLY) remove the cover and take a look at the fan.
Might be a wasp nest in there causing an unbalanced and overweight fan.

That could make the fan noisy and increase the start up load (in addition to the compressor) that exceeded the amperage rating of the breaker long enough to trip it. (Especially if the voltage was on the low side to begin with.)

had similar problem, if a/c is on elect hot water heater and coffee pot, my breaker would trip...... found that info in the owners manual after the fact that is normal for 30 amp system..... now I just use gas for hotwater and never use elect hotwater heater, has not tripped again

RV is at the dealer right now, they think the problem is the motor. They said it's not spinning freely like it should causing it to overheat and trip the breaker.
They're getting a new motor and installing that.


Gregtx- when I tested this out at my house I didn't have anything else on. In fact the water heater breaker was turned off at the time.
