StingrayL82,
OK, that green color on the black wire connected to the bottom of the second fuse bothers me. This appears to be corrosion and that is bad. It will cause heat.
First turn off the shore power.
That corroded connector needs to be cut off and the wire cut back until you find clean wire with no corrosion. Then put on a new connector and clean up the screw and buss on the bottom of the second fuse, then reconnect the wire.
Turn the shore power back on for about 15 seconds, turn it off, then see if the connection is hot. I use an IR thermometer for this type of thing, but you can use a finger (carefully) in a pinch.
If it is still cool, try the power for 30 seconds and check again. If still cool, then turn on the refer for about 30 seconds and check again. If still cool, then try for 5 minutes. Note that refers on 12vdc draw a lot of power, so a little resistance can cause a lot of heat. Because they draw so much 12vdc power they are normally only used when driving so they don't kill the battery.
Do you have an electrical meter? If not, you should get one and keep it in the RV. You can get one at Harbor Freight for about $10.
I already re-wired all of the 12VDC wires going to the fuse block. I also used JB Weld made for thermoplastics and re-attached the lower fuse connector for the fridge fuse. Everything is cool to the touch, as I do not have an IR thermometer.
I have a digital Sears multimeter. Wife also just bought me a 120VAC circuit tester, while she was shopping today.
