No AC Power

[toddperry491]

Newbies here. Love camping. This year got everything ready to go. Air conditioner and outlets have no power. Lights, radio and anything on DC power working. Thought at first it was just they Air conditioner. Replaced capacitor. No AC power at all. Help.

[Kimber45]

are you plugged into shore power?

[toddperry491]

It was plugged in to my house.

[Bama Rambler]

Did you check all the breakers in the house and the RV?
How are you plugged into the house? What adapter are you using?

[Kimber45]

welcome to the forum. this thread is going to go 100 different ways quick. depending on how you are plugged in at home I would not be trying to run the a/c or there may not be enough juice to get it going.

[toddperry491]

I am using the power cord and adapter that ca me with the camper

[bikendan]

Did you plug the cord into a GFI outlet? If so, it may have tripped.
It would also help if you put your RV information in your profile.
We have no idea what type of RV that you have, nor brand or model.

You still haven’t answered how it’s plugged into the house. Are you using a 30A -> 15A adapter to plug into a standard household outlet? If so and you ran the A/C you either tripped the breaker in the house breaker panel or you tripped a GFCI outlet that’s on the same circuit.

First step is to test/check the outlet on the house. Getting power there or not? If not then it’s a problem on the house side. If you have power there then the issue is on the RV side, could be a bad adapter or something upstream. You have to follow the path the power flows and figure out where it’s stopping to know where the issue is.

Just as above you need to check:
Outlet you are plugging into is it GIF or switched
House breaker
RV breaker
The cord
the Adapter
the Converter on the RV

The house breaker is ok the gfci in the camper doesn't work and when I check power out of any of the breakers I get nothing

[pkmkaz]

Correct me if I’m wrong, but I was under the impression that if you adapt a 30 amp “shore power” outlet down to 115 volts, the only things in the RV that work is anything OTHER than the AC... the AC draws too much amperage.

[toddperry491]

It was working a couple weeks ago when I was checking everything

That is correct and wrong all at the same time. when you are running off your home necked down you only have 15 amp or 20 amps depending on the circuit you are plugged in to. everything should work but not all at the same time. allot of folks will run on a 20 amp circuit. I prefer not to.

Plug something else into your house outlet that the RV is currently plugged into(after removing the RV cord), and make sure that outlet has power. Just grab a hair dryer if nothing else handy.

If you have power at the house outlet, then we can move forward towards the RV.

You have to start with the basics...

Do you own a multimeter and know how to use it?
If so...

Do you have power in the house outlet you are plugged in to?

Do you have power at your adapter? (before plugging your shore power cord into it)

Do you have power at the end of the cord that plugs into the side of your R/V?

Do you have power at your breaker/power distribution box in the R/V?

[toddperry491]

Ok so maybe I damaged the camper cord?

Not talking about GFCI in the trailer. You need to check for a GFCI outlet on the house side that’s on the same circuit that you’re plugged into. Just because the house breaker is OK doesn’t mean you didn’t trip a GFCI outlet on the same house circuit. You need to verify if the house outlet you’re plugging into has power or not, as I mentioned above. If you don’t hav power at the outlet then you won’t have power in the RV. Check methodically from the house breaker to the house outlet the RV is plugging into if you have no power at the outlet. No use checking random points in various systems, follow the path.

Regardless of the amperage the voltage is still 120v. The RV has no idea what amperage it has available, so trying to run the A/C on a 15A outlet will typically trip the breaker or GFCI outlet on the house side due overload. The A/C uses 120v. Amperage doesn’t tell you what the voltage is so the comment about adapting 30A to 115v makes no sense. The 30A RV outlets are all 120v.

[toddperry491]

Yes I have 120v on the outlet

[toddperry491]

All have power except the power dis yt? Ibution box in the camper

And do you have 120v coming out of the adapter that the RV plugs into? Are you using one of those black hockey puck looking adapters or a dogbone adapter? Regardless, check for voltage coming out of the adapter.
