120 volt outlets not working, need help!

[whit]

Hi all,
I purchased a 2005 Dolphin class A motorhome last year and it has been great. However today while cleaning it I noticed the electronics (DVD, Digital Box, etc.) cabinet had no power. My motorhome is plugged into a 30 amp outlet at my home. I used a tester and I am getting full power at the breaker box. No breakers are tripped. I thought for sure it was going to be a GFI, however I checked all of them and they are not tripped and all have power. There are 3 unless I missed one, but I don't think so.
The outlets not working are in the electronics cabinet above the passenger seat, one outlet down by the floor next to the passenger seat, the rear bedroom outlet for the rear tv, and oddly enough, the refrigerator outlet.
There was a 2nd, unused outlet in the refrigerator panel that worked, so I replugged into that. so at least my refrigerator has power.
I don't know what else to check?

Thanks, Mike

Whit: have you fix the problem yet. I have a 2003 Georgrtown and i had the problem. I had 3 outlet that would not work. I got to pulling out each outlet. On the 3rd outlet when i pull it out. this was the type you push the wire in instead of screws to hold the wire in. My solution
was i look for months for an outlet. the outlet was osblete. what i did i by pass that outlet
and then all the others work. Hope this help.

Your inverter should be in one of the back outside compartments on the curb side adjacent to your battery compartment. On the inverter are 3 circuit breakers, the 30 amp one is input power, 15 amp one for the micro wave and the 20 amp one feeds the tv and almost all other 120 volt receptacles, notice I said almost all the ones off the inverter, there are a couple powered directly from the main ckt bkr panel such as block heater and some rear bed room. I believe your problem is that 20 amp breaker on the inverter. Let us know what you find! If this doesn't fix it also let us know for further troubleshooting. Blessing ;Keith

My inverter has three circuit breakers. One for each leg of the incoming voltage and one for the charger portion of the inverter.

Ours has two breakers located on the generator itself, and they are a real pain to get to. Have to open hatch and remove cover to get to them. So guess what. Seems like I am always haveing to get out, and reset at least one of them. Just about anything unusal will trip one or both of them. A real pain!

I would suspect, just a pure SWAG, it's pretty near where the shore power cord enters the RV. That's where mine is.

Good luck on finding the inverter. I'm pretty confident that the problem is associated with it.

Also look near the fridge in the vent cubby on the outside. I've seen GFI's placed there that sometimes trip.

Question: Have you found it yet.. I've seen this several times and it is almost always the Inverter breaker tripped.. And to give you an idea of how common it is.. I'm not an RV service technician.. So it's just helping neighbors and I've seen it many times.

If you haven't already checked it, don't forget that there is often an outdoor outlet for attaching a TV or whatever. Once we had this problem, checked everything inside to no avail and finally called the factory - they reminded us to check outside, which turned out to be the tripped GFI.

double post. wrong click.

My 2001 Dolphin...has a CONverter and and INverter. The INverter, after all these years is starting to fail. Exactly what the OP describes.

In my Dolphin, 2 outlets in the front...the one under the dash by the passenger seat and the one where the coffee maker is plugged in. It also controls the very very front where the TV and such are...and for same strange reason the 2 outlets in the BEDROOM. (Don't ask me)

In the past year, I've had maybe 3 failures where the INverter circuit breakers had to be re-set...and once where my RV dealer, on the phone, told me to un-plug it, let it sit for a minite or two...the plug it back in to allow it to reboot.

This spring, the INverter is being bypassed...by removing it. Seeing I have little talent for electrics, my RV mech is doing the job and assures me I will have no problems with that circuit.

Pricing, on the 'net, a new INverter....wow. $14-1500 for something I simply have never used (like for the coffee maker).

I had this same problem in my Bounder.
Turned out to be a tripped circuit breaker on the inverter. Some of the 120v outlets run through the inverter. None of the breakers in the panel were tripped but there's a push/pull (mine has two) breaker on the inverter.
My inverter is installed in such a way/position that it was sort of hard to see. But, I couldn't figure out why I had no power to just certain things. So I started looking at EVERYTHING electric, just happened to "stumble" across the inverter breakers. That's when I saw one was tripped.
We have the same kind/type of breakers in one of our airplanes.

The devices you describe leads me to the Inverter/Charger. It is very common for breakers to trip right on the converter itself. 110 volts passes through under normal conditions.

The refer socket that was dead is probably for an ice maker section of it. The entertainment stuff would naturally be on the converter/inverter path.

My only experience like this was when all the sockets on one side of of my 5th wheel quit working. Turned out that I had not pushed in the power cord to the outside of the outside of the trailer completely in and did secure the lock ring correctly.
