Hey all, I'm a new RV owner and new to the forum. I wish my first post wasn't because of a problem I was having but I do need some help.We bought our 2014 heritage glenn 356qbq about a month or so ago to live in after we sold our house and while we were building a new one. We've been living in it for 3 weeks but have noticed a reoccurring problem. Randomly the 120v power will cut off leaving just the 12v stuff running off of the batteries. I check the campers breaker box and nothing is ever tripped, I then check the dedicated 50amp breaker that the camper is running off of and it's never tripped, I then go to the receptacle to make sure it hasn't pulled out and I've never found it moved but yet the power will stay off for usually around an hour to an hour and a half, until suddenly it'll cut back on.It's happened 3 times now, and all 3 times the power has come back on at a time I'm not actively doing anything, like I'll be standing in the living room thinking and it'll cut back on. Since this is my first camper I have very little experience, so I'm hoping someone can point me towards some other things to check.Thanks in advance for an help!

I've also checked the power at the breaker box and going into the camper at the cord outside with a multimeter and there's no problems there either.

Sounds like a loose connection..check all that you can find.

Next time it goes off use your multimeter to check if you have power at your power distribution box where the breakers are in the camper. You may have a loose connection there where the power comes into it. Your multimeter is going to be your best friend for tracking this problem down. When the power goes out start checking at the furthest point of your camper and start working toward it until you find where the power stops. Do you have a 50 amp cord plugged into a 50 amp outlet or are you adapting down to something else? That may be your problem too.

Thanks for the replys, the power cord is plugged straight into a 50 amp 4 prong receptacle, no adapters. I will check for loose connections tonight.

Do like Doug says. Might pull the breaker panel off and check for loose screws. Unplug from pedestal first. Maybe get an Electrical person to help you if need be. I am a good troubleshooter. You may call me if you like.

Maybe the previous owner installed a surge protector? Some units will shut off power if voltage is too low or too high or there is a fault in the ground or neutral lines.

Exactly what I was thinking.

Ok, when I got home my wife told me the power had been off for hours. So I went straight for the campers panel box. I got all 4 screws out that were holding the cover on and the instant I started pulling the cover off the power popped on, so it's definitely in the panel box. I checked every screw I could and couldn't find one that was loose. I wiggled every wire that I could and never saw even a flicker in the power. Hopefully next time it goes out it will stay off long enough for me to get the cover off and the multi meter in there.

Thanks everyone for the replys, I will update this post the next time the power goes out..
I haven't heard of a surge protector being installed on it, how could I tell if there was one?

Follow the RV power cord where it goes inside rig...then look for a EMS box/Surge Guard controller
