Fuse Box Wiring

[djellis]

Furnace quit working (nothing comes on as in no power) so I looked at fuse box first. Fuse also runs water pump. Water pump no power either.
Swapped out 15 amp fuse. Still nothing. I have been parked for a couple years (full-timer) in one spot on grass. I have had problems with Texas Crazy ants getting in electrical outlets and blowing GFI. WF-8900 Series converter is located under stove. Can I pull it out from the front to check where the wires are connected to the fuse to see if that is where my problem is? Anything else I can check?

Pull out the fuse and use a 12v test light to see if you have power to the fuse socket before you yank the converter out. If no power, then I'd look behind the converter.

Tested it. Getting 12 volts and water pump is working. Forgot to turn off shore water before testing. So I have a furnace problem. Will start working on determining problem. Thank you for your help.
