Moved RV 2 feet and now power to AC isn’t working

[AbelMara]

Is there an auto shut off? We moved a few feet with the power still on and after moving the AC power isn’t working. The power cable is in, power on, fuses good. Ideas?

Welcome aboard! I'm not an electrician but maybe a couple thoughts.

First, there are no fuses on the AC side. Shore power is 1 leg on 30amp and 2 legs on 50amp of 120v power. They run through breakers. Any fuses are 12v and run on the batteries which are charged by the power converter when the AC power is connected to shore power.

So, all breakers are on? Did any trip and need to be reset?
Have you unplugged from shore power, waited a few seconds, then reconnected to shore power?

It doesn't make sense that you should lose AC power by just moving the rig a couple feet...unless, maybe, there is a problem with the power cord. Have you inspected it to check for any burn marks? You might also need to break out a volt meter and start checking power at the post and continuity in the power cable.

Do you have an EMS installed? Are you using a surge protector?

Yes, thanks, did all that….still looking. Seems like it must be an auto sensor.

Everything seems to be in order-but it really seems like there must be a Motion sensor shut off. Ideas? My husband is gonna kill me for not typing the right questions, but he knows what he is doing…I’m just trying to help by asking. lol!

I'm not aware of any motion sensors. I move mine often a couple feet while plugged into shore power. Never an issue.

If it were me I'd be checking everything with a volt meter, starting at the post and tracing to where current stops flowing.

What year, make, and model is your trailer?

Another thought...are you plugged directly into shore power or are you using a dog-bone adapter?

It’s the ATS, which was set up for gen prep. It’s a recurrent problem apparently in our model. We don’t have, nor will we have a generator, so we can just bypass the ATS. FYI. Whew. Our model only.

Glad you found it. Yes, those can be problematic. Sorry I didn't think of it...we don't have one in our rig.

My camper has a fuse for the furnace that feeds the thermostat and the AC will not work if that fuse is blown
