Electrical outlet problem

I have a 2002 Georgetown 326 and having a electrical outlet problem. I had 2 heaters plugged into an outlet (one on high 1500w and the other on low 750w) near the dinette outlet. Well, they worked fine until I turned other heater on high in the morning. Shortly after, I heard a crackling noise in another outlet located in the bedroom (all it had was a laptop power cord plugged into it. That caused the outlet with the crackling noise and several outlets in the 'chain' to go dead, as well as the converter and the fridge power. I checked the breakers for voltage and they were fine. I then took out the affected outlet box that made the noise in the bedroom, and snugged the wires down good. Well, strangely, the affected outlet and 3 others started working as well as the converter. Only 2 outlets (one being the outlet the heaters were plugged in to) do not work and the fridge on shore power doesnt work ( we are using propane to power the fridge). So, it seems snugging those wires down improved the situation a bit.

The circuits that were unaffected seem to be on the GFCI circuit. The bathroom has a GFCI outlet breaker. But the affected circuits dont seem to be on that GFCI circuit.

Since I have 50 amp service, would I have another GFCI circuit located in the coach? I looked all over, but only see the one in the bathroom.

ANY help with this issue would be greatly appreciated!!

You exceeded the 15 amp circuits and the receptacles are only rated for 15 amps and are on 15 amp circuit breakers.
1500 watts and 750 watt = 2250 total watts and using 120 volts it equals 18.75 amps.
The crackling may have been the actual arching of the contacts within the receptacle.
Don't put both heaters in the same outlet/circuit or you probably are asking for a problem/fire. Look at the heater male plugs ends for burnt metal or darkened.
Plane and simply you over loaded the receptacles max amps.
What kind of answer are you looking for?

Well, before I began working on the outlet box that caused the problem, that affected box and 5 other boxes did not work, that is 6 total. After working on the originally affected receptacle, that allowed 3 other circuit outlets to work. So, now, only 2 outlet boxes do not work (including the fridge on shoer power).

Could it be that the outlet I worked on is still the problem and is causing the 2 remaining outlets from working properly? Is it possible I really just need to replace the affected outlet box that was making the sizzling noise? Seems odd that after working on the affected box, it only allowed 3 of the 5 outlet boxes to work and not all of them.

Sounds like you overloaded wiring and probably burned up the wire in a portion of the series wiring run. You may have to pull new wiring between those two outlets and replace outlets too. If a gfic outlet was in the other portion it may have saved the other run. Running them all night at near 20 amps had wire good and hot. Turning up second heater taking you up to around 25amps sizzling!

It takes a couple of minutes at 25 amps to trip the breaker (they use heat to open).

That is enough time to really do a number on your electrical equipment. Most likely there is a failed GFCI you have yet to find or a burned wire at the outlets.

Unless you are an experienced electrician I would not try to fix this yourself after having that big of a problem. You don't know for sure what and where damage has occurred so why risk your life on a possible electrical fire.

I agree with Bill here.
I have been working the electrical trades since 1968. Please don't take this wrong.
Sounds like you have a small amount of knowledge about electricity and you need to have someone who can easily identify the problem and repair as needed. What you have said and the questions you have asked shows me you really need someone experienced to work on it.

As always Herk you always demonstrate and show the problems very clearly. Thanks. But I feel this issue needs a qualified person to repair.

Thanks for the photos and advice. My knowledge of electrical systems is limited, but I feel strongly that there is a (hidden) GFCI hiding somewhere in the coach. I did replace the at fault outlet box and in doing that, allowed 4 other outlet boxes to begin working again. I suspect those outlets were in the daisy chain. The GFCI outlet that I could locate is in the bathroom, but I am 100% sure the previously affected outlet was not on that circuit. I believe, as well as a couple of others, that there is another GFCI outlet in that coach as it has 50amp service.

Is anyone here familiar with a 2002 Georgetown 326 model? If so, could you please help us in locating the other GFCI(if in fact there is another one)?

The purpose of a GFI is to trip quickly if it senses a quick short to ground.
They are used close to sinks or water and are also attached to outside outlets.

Any outlet on beyond the GFI is protected by the GFI.

All other outlet wiring should come from the electrical panel and controlled by a circuit breaker.

You can check the outside compartments to see if you can find a GFO outlet in there.

This is the best information I can give you without seeing your motorhome.
