Hello: 2021 Sport Trek 312 here
Breaker is a double.... 15 on left (microwave), 20 on the right (AC). 15 tripped several times and finally microwave wire is dead. I replaced the breaker, still no power. Wire insulation cover on microwave wire is white while the wire coming into the breaker box has a green cover so the wire is connected "somewhere." KZ says they don't have wiring diagrams which is the dumbest thing I've ever heard but nevertheless, I am trying to figure out where the green wire connects to the white wire in hopes of finding a disconnected wire. I turned ever single breaker on and the 15 off, then checked ever single power outlet, light, etc. in the camper and all have power so this is a direct wire somewhere or so it seems.
Anybody seen this or have additional ideas?
Thanks,
Tim in Texas

I have no clue what you are saying. The AC system in a trailer is the same as in a home, black is controlled by the breaker, white is neutral and green or bare is ground. Green is never used to carry power. Photos might help.
Did you remove the outlet for the microwave? Are the wires connected properly behind it? Those self-contained outlets can be troublesome, they exist for quick assembly reasons. Did you check for power across the black and white wires? Did you check for power at the breaker?
There are no wiring diagrams, wiring is tossed in at assembly and no two are the same.

The AC system in a trailer is the same as in a home, black is controlled by the breaker, white is neutral and green or bare is ground. Green is never used to carry power. Photos might help. When I refer to "green," I'm saying the outside wrapping that contains the three internals wires is green (see pic, 15 side)  coming in to breaker but white (see pic)  going to the outlet for the microwave. The AC is irrelevant here because it is on the 20 amp breaker side and works fine.
Did you remove the outlet for the microwave? I did not remove it but used my tester and detected zero power anywhere on the wires going to that outlet. I can certainly try that. Are the wires connected properly behind it? Those self-contained outlets can be troublesome, they exist for quick assembly reasons. Did you check for power across the black and white wires? I assume testing the main white wire (containing the tree wires, white, black and bare ground) would be sufficient. There is no power detected. Did you check for power at the breaker? Yes, power is leaving the breaker.
After watching some manufacturing videos for RVs, I'm assuming the slide was built at one station while the chassis and other parts of camper were built separately. Perhaps the wiring was installed in the slide for microwave, fridge, TV and once the slide was assembled to the main chassis, those wires had to be connected to wiring that was assembled to the main chassis hence the white to green wire scenario. I intend to get underneath, remove a belly pan and hope to find where wires are connected. Perhaps it's a simple disconnected issue.

You will have to open the actual outlet up and see if one of the wires in the outlet came loose. I had that happen in my unit. The fridge and outlets on my counter went out, had to hit the starting point and follow where the electric stopped. It was a loose connection that just went out. If it was popping the breaker, You should see some burning because it might have been shorting out to pop the breaker.

You might be able to see the green sheathed cable behind another outlet, pop a few of the most likely suspects. It appears that you have a good opportunity to replace that poorly installed, junk outlet behind the microwave with a real one in a box.

It appears that you have a good opportunity to replace that poorly installed, junk outlet behind the microwave with a real one in a box. Since I turned off the questionable breaker, and then found power at every single outlet including all lights, TV, fridge, outside outlet, etc. I "assume" there is only the microwave on that circuit. Manufacturer didn't even know. I'm really hoping when I drop a few belly panels I find that green sheathed wire and then I should be able to follow power. Thanks for the input! |

The microwave should be the only thing on that breaker, however we know that the cable changed color somewhere. Code does not allow a splice outside of a box. One of your self-contained outlets may have been used as a junction box and maybe you will find green behind it, just because the outlet works doesn't mean that the connection to the outgoing cable is good.

There will be junction box where the slide room is connected to the main body. This box must be accessible, so look in the corners of the slide room for a blank cover, or inside one of cabinets. You can also under the slide for where the wiring is going into the slide, that might give you an idea as to where the power is coming into the slide room.

The guys building these things wire, and plumb, them as they seem fit, on any given day. (/cynic mode) Lyle |

I had our Microwave stop working after it came back from dealer, found wire off on plug that Microwave plugged into ...
Tight spack over Microwave to work on an only a single plug, had to take door off over Microwave to work on such so
it wouldn't keep hitting me in head ... What should have been a 20 minute job at most took me over a hour an 5 tools
to connect one wire back into plug LOL
