Why Does The Fuse To Our RV's Water Heater Keep Blowing Out?
by Anne Beldman
This fuse keeps blowing. We cannot use our hot water ...and wonder if this could have anything to do with the cable to the TV as when we connect to the park the connection gets very hot. We have had a RV electrical specialist here for six hours and he cannot find out what is causing our fuse to blow and our cable connection to get hot (so hot you cannot touch it) We now use a spare cable and bypass the Minnie Winnie which runs out of the passenger door.
Help Please, We are in a remote park and not close to an RV repair shop.
Greetings Anne thanks for submitting your question on our Ask An RV Question Page.
First let me say that I am sorry that you are going through this. The fact that you have had an "RV Electrical Specialist" trying to diagnose this problem for over 6 hours and he/she cannot find the problem concerns me. It may be time to get someone else in to take a look at the problem.
The symptoms you are experiencing can be caused by several conditions. The first step that needs to be taken is to determine if the problem that you are experiencing is being caused by the electricity you are receiving from the RV Park or if the problem is in the electrical system in the RV.

A properly equipped "RV Technician" can check the electric being supplied to your RV at the park. They should check the electrical connection from the RV Park for proper ground, correct polarity and proper voltage (not too high and not too low).
I would also suggest that they check the cable TV connection at the RV Park to make sure that no high
voltage is being passed through the cable connection. As there is no reason for any Coax cable connected to a TV to get hot unless it is receiving high voltage. By the way any of the electrical problems mentioned above could also potentially cause your TV to pass voltage to the Coax TV cable.
If all of the testing on the RV parks electrical system proves to be normal then we can safely assume that the problem is in the electrical system of your Motorhome.
Having your RV's electrical system thoroughly tested may require a trip to an RV repair facility where they have ready access to the tools and equipment needed to diagnose and repair the problem.Now protect all of your Vehicles and your family while on the road: Join Good Sam Emergency Road Service Today and save!
My best guess is if this is the first time that you are experiencing this problem that the problem is going to be in the RV Parks electrical system. Before you go to the expense of getting another technician out there, I would suggest that you move to another RV space and see if that eliminates the problem.
I wish I could be more helpful, but I am at a disadvantage not being able to actually be there to run the tests myself.
I hope that the information I have provided is useful
