Mine was zip tied to the top of the Styrofoam covering surrounding the heater and new replacement was the same way.

Thanks for the replies. Does this mean I will have to pull the entire water heater out in order to access the control board? I was hoping I would be able to access the control board from inside the rig.

It depends on your model RV Floorplan. Mine, 3130re, I can take off the kick panel in the bottom of my pantry and the water heater is right there.

My water heater is on the door-side and can be accessed with the wall panel removed in the passthru.

OK, I have to ask: What is the problem with the WH, no hot water on either Gas or Electric, only on Electric, or only on Gas.
There is no real control board that I know of in that unit. The board that is taped to the side is the board to provide spark when on Gas. Electric is directly connect to the element after passing through the T-stat/Hi limit switch.
We really need to know the actual issue before proper answers can be given.

Some can also be accessed thru the wall in the basement.

Have a 3750FL legacy
You can remove the grill under the fridge and have access to the water heater and furnace.
Panel fits tight.

How about a picture of your WH with panel removed. Would be interested in seeing the fan and fan wiring specifically.
