Fuzion GFCI

[Pearce369]

We purchased a new 2023 Fuzion 428 1/24, It has tripped one of the GFCI"s ever since we purchased. I have taken it to th e dealer 12 to 15 times in the last year, Service says it won't trip while they have it but they only have it in the service bay for minimal times while working on other issues. I had my electrician install my 50 Amp shore power. I have checked all the outlets connected to the GFCI, all seem to be fine. I have residential refrigerator and have removed it from the slide and unplugged it to check the outlet. GFCI has not tripped without Refrigerator. I elected to plug it into another GFCI outlet and it has not tripped. my question is does anyone have an idea if it might by a bad GFCI, I don't think it is the frig because the other GFIC has not tripped! Any ideas where to check next?

I have pretty much the same setup on my Alpine. Mine was tripping the GFI when I got it. It was so bad that I disconnected the load side of the GFI and tied it all together on the line. This of course stopped the GFI tripping but then the breaker started tripping. I found a wire in the receptacle circuit that was being pinched when the dining room slide was let out. I repaired that cable and solved my issue. Sometimes appliances that have motors will cause GFIs to trip.

The GFCI is on a multi-outlet string and could be throwing a fault anywhere on that same circuit. As Randy suggested, I would start by looking at the wiring in or to the slide-out where the refrigerator is located. Do you have one of those plug-in circuit testers? They are inexpensive, but can help diagnose electrical issues pretty quickly.

Gfci

Thank you for your replies. I had service replace the GFCI with a new one. I inspected all of the outlets i was able to identify and all circuits check good with my test equipment. I plan on pulling the GFCI and checking it to make sure the service department didn't make a mistake replacing it! It is so bad that I will not put food it because it would cause food to spoil.

This is "speculation only" but I'd suspect that somewhere along that GFI line you have a missing neutral. It doesn't happen "all the time" but with the slide movement, a wire "under there somewhere" breaks contact and the GFI trips.

Now, there is a "converter plug" called a MOLEX connector located INSIDE the trailer, next to the slide. The purpose of that MOLEX connector is to connect ROMEX "single strand wire" to flexible "multistrand wire" that can be bent and survive the multiple slide extensions/retractions. I'll post a photo later in the thread to show you what a MOLEX connector looks like. If you locate that connector, I'd suspect you'll find a loose wire or a broken wire either going into the MOLEX or exiting it. That "exit multistrand wire" goes under the trailer, sits in a "wiring mold" that bends when the slide is retracted and extends when the slide moves out. Then that multistrand wire goes "up into the slide" (probably along the sidewall where it can be protected by the wall mass) and then to the refrigerator plug.

That multistrand wire is just a "short piece of extension cord type wire" and is subject to not only flexing, being pulled and pushed with every slide movement and is exposed to anything "hazardous or dangerous" in the wheelwell.

So, I'd start looking for that MOLEX connector, spend some time making sure it's properly wired, the connections are tight and the MOLEX is properly connected and then secured in place. Follow the wire going under the trailer and inspect it carefully. My guess is that you'll find your "issue causing the GFI to trip" along that flexible multistrand wire.

GOOD LUCK, Here' are the photos of a MOLEX connector.

You need to let the slides out and climb under both of them. That circuit goes from the bathroom to the kitchen slide and over to the opposite side slide and likely connects to an outside receptacle. The cables are in the wire looms that fold up when the slide goes in. When my slide went out it was stretching and pinching the SO cable that fed the dining room slide receptacles. A wire repair and some Nuke tape fixed it right up. You can unplug the fridge from that circuit and plug it into another one that isn't GFI. I suspect if you don't have a pinched wire you have a loose wire in one of the receptacles. Identify all of the recepts on that circuit and check them. Those press pin boxes are terrible.

Followup

Thank you I need all the advice I can get. I talked to my electrician, and he said he will come and see if he can find it if I don't. I have the refrigerator out and plugged into another GFCI and have not had an issue with it tripping, so it has to be in the wiring associated with the other GFCI. I will continue to post and hopefully will have an answer picture included when I get to the problem!

Thank you for all the help I started tracing down the wires and the outlet for the refrigerator and when I opened the outlet box the main feed wire was so loose it fell out. I attached a picture which shows bent connectors and the box warped from wires being improperly installed! After replacing the receptacle and box with residential fixtures and outlet, it appears i have solved the issue, the GFCI has not tripped. I plugged the refrigerator back in and everything seems to be resolved. Just another example of poor workmanship in the manufacturing of RV's it appears that all manufacturers have the same problem! Service seems to have problems with qualified technicians to find and fix problems especially electrical. There should be stricter regulations and inspection of the manufacturing process. All the electrical system should meet the same standards as homes to prevent this quality control problem which can lead to fire issues!

Thank you for your help I found the Molex connectors, and all seem to be tight. Interesting how this all is tied together I found a loose screw on the GFCI and repaired it but it made no difference. I did post a picture of what I found and replaced a outlet with residential outlet and box. Apparently improper installation was the problem box warped, and the wires fell out when I removed the cover on the box. Blades in outlet were bent' Thanks again
