110v Outlet Issue

In your power distribution box, as per the photo, you have 7 breakers for the 110 volt side and you have 9 fused 12 volt circuits.  I believe the 2 / 40 amp fuses that are separated are for the reverse polarity protection on the trailer.  Your trailer is a 2016.

I have a 2019 179, therefore the wiring schematic has changed over the years.  My trailer is currently in storage, so I can’t go to the trailer for the ready reference, which is needed. At this point all I can do is go from memory (which isn’t great for me at this point in time).  On my trailer I have only 3 – 15 amp breakers labeled; first fuse, Interior lights, A/C (for controlling purposes only), second fuse, LP, WH, MP, Pump (powers LP-LP/Carbon Monoxide Tester, WH powers water heater controller, MP powers tank level indicators and monitor panel, Pump powers water pump), third fuse, Bath lights and fan, stereo radio. There is a 1 – 7.5 amp fuse for the furnace fan. Also there are 2 -30 map fuses the first one is labeled for the 2 slide out motors and the second fuse is labeled for the battery and the Refrigerator heating element. As you can see our trailers are wired differently on the 12 volt side of things.

On the 110 volt side my trailer has only 4 / 15 amp breakers, 1 / 20 amp breaker, and 1 / 30 amp breaker.  The 15 amp breakers are labeled for; the first is, converter, the second is for the GFI outlets & Refrigerator (heating element), the third is for the Microwave, the forth is for the electric heating element in the water heater. The 20 amp breaker is for the Air Conditioner. The 30 amp breaker is for the incoming shore power to the distribution box.

With all this being said and going from my memory the wiring in my trailer for the GFI outlet which is located between the bed and the dinette low on the bed support and then feeds the other in house 110 outlets which are 2 more by the kitchen counter (one on either side of the trailer) a third one by the television and the last one is mounted on the outside of the trailer. All of these house use 110 outlets are “protected” by the GFI outlet by the bed/dinette.  

Using a multi meter verify that you have 110 volts to the GFI outlet. If you don’t have power to that outlet, find the problem between that outlet and the distribution box. As a side light none of the house outlets are feed by the 12 volt system in a standard wired trailer.  You are correct in thinking that the refrigerator, microwave, and TV are on different 110 breakers.  It also may be helpful to find the labeling electrical schematic. Mine is mounted to the inside front cover (door) of the distribution box. Another side light to my understanding is that there is a converter in the distribution box converting 110 volts to 12 volts (battery) going to the battery. The R-Pods made in 2016 did not have as standard equipment an on board inverter to convert 12 volts (battery) to 110 volts.   Hope this helps.
