Hot Water Tank Element

Has anyone replaced the heating ac element in a 10 gal national tropical?
where is it and how do you get to it to remove and replace it?
I know my gas works but I think when I bought it the previous owner Burt the element out
when I switch on the 12v switch the gas works but when I put the 120 ac on nothing want to check the power to the element and the ohms
thanks in advance

What brand and model? After you know that, go online and search for an owners manual. A parts diagram will most likely be found. The diagram should be good enough to figure out how to remove it.

Two posibilities.....1) If you have an "aftermerket" installed heating element, then it is installed in the drain plug hole on the front of the heater, easy to get to. If it is "original", then it is installed in the back of the water heater, very difficult to access without cutting an access hole in the cabinet face inside the MH, (that's what I did) Rook

Best answer^^.


The two major brands, Atwood and Suburban, locate the elements in different places. Atwood is typically at the rear, hidden from easy access, whereas the Suburban is located in the front, behind the outside access door, and is easily removed.


My former coach, a Tropi-Cal, had an Atwood heater but I didn't have to change the element. My current coach has a Suburban 10 gallon and I recently replaced the element. Very easy with the proper tools.

Before you replace the element, see if there is a red 'reset' button behind the cover. Most electric elements have a built-in safety to prevent damage if it's powered up without water in the tank. Simply pressing the red 'reset' button may be all you need.

Ditto to what Richard said. That RED reset button is on the back of the tank. Rook

The above post provides very good info about the 2 different brands.




In your profile you post 2005 year RV
If you have an Atwood it could be bad element BUT could also be a DC Voltage issue.......No DC on 'electric' controls, Bad DC/AC Relay, Bad AC wires on DC Relay or bad element

Element, DC/AC Relay along with associated wiring is under protective cover on backside of water heater tank


Access to backside could be from inside RV, from a removable panel in compartment next to water heater, from removable panel underneath RV

Atwood Wiring






IF Suburban ...much easier
Element under cover behind/below gas valve
120V AC wiring is direct----Circuit Breaker to AC Junction Box (on backside of tank) to On/Off to set of t-stats to element













So as you can see.......matters WHICH Brand/Model you have




AND what year of RV........
No Reset on Atwood after 2003 (2004 versions do not have reset for ECO/Hi Temp T-stat)

I have a 2006 National RV Seabreeze LX 8321, does anyone know where the hot water tank is located? I sure can/t find it and it's a 10-gallon one. I found the 120V and 12V switches on the control panel and that's it.

Just look for the outside panel. It's got a quarter turn latch on the top. If that doesn't work. Run some hot water and turn on the propane part of the water heater. Now,,,,,, go outside and find the roar of the flame. Don't ask how to get back in the coach
