Wiring after installing a residential refrigerator

Replaced our Dometic refrigerator with a residential one. All is well with that. Since then we noticed one LED light above the sink and the range hood motor and light do not work. The fuses are all okay, but the appliance 15 amp fuse doesn't seem to have power. When removing wires from the Dometic circuit board, I tied together 2 whites and then tied together two white/blue stripped wires. Could this be the problem? Any ideas from the pros here? I'm out of my league with this RV wiring. Thank You for any ideas.

I am sure that you have done this already, but change the fuse for that particular circuit. You likely blew it disconnecting original fridge.

Second, go back and verify that your junction (twist caps) are indeed engaging copper of both wires they are put on. I can't tell you how many times I folded over smaller wires by mistake, particularly working on tstat wiring on air conditioners.

Third, if still no power, then connect a small 12v battery (jump box, drill, etc) to each wire pair after removing fuse. If items in question work, then you have a broken wire leading to fridge.

Fourth, if fuse is good, and there absolutely is no problem with wiring, then look closely at fuse block. Make sure fuse is engaged on terminals on both sides. Also look at fuse board for burn marks, etc. look on back side too.

If your fuse block has blown fuse indicators, use those to your advantage to troubleshoot with. Turn *everything* on. Remove fuses. If the indicator for blown fuse on that circuit lights, you likely have a break in the wiring. Start turning devices off. When indicator goes out, your problem will be located between last working device and next device (or junction).

Hi ! Welcome to IRV2! We're sure glad you joined us!

Were the wires that you tied together on the same terminal ?

Good luck, happy trails, and God bless!

Thank You!!!!!

Krbjmpr it was #2, and I see MSHappyCampers figured it out too. Can't express my thanks enough. When I disconnected the Dometic refrigerator, I put a wire nut on each single wire because in my mind I was isolating the wiring from the old refrigerator. I didn't know they were to be connected to make a circuit to run the hood vent, light and sink light. Everything is now working correctly just in time for our big trip in a couple weeks. Thanks, thanks and thanks again.
My orginal post said I tied together the 2 whites and tied together the 2 white/blue wires. My error with that sentence.
