I need to replace my Atwood water heater model 9E. This one isn't available and Atwood tells me I need the 10E #96163. I will need to rewire my AC switch because of the new modifications that only allow fro 12v switching. Is there an older model that I could replace it with, without changing the wiring?
Thanks

In late 2003 Atwood changed the design/controls in their 2004 Model (and all models since)
Prior to that change....electric was wired directly for 120V AC and had it's own set of T-stats and ON/OFF switch. Propane was wired directly for 12V DC with it's own set of T-stats---circuit board and On/Off Switch

Newer Versions (4E for 10 gallon & 10E for 6 gallon)
Electric & Propane use same set of T-stats, same 12V DC circuit board for controls, 12V DC On/Off Switches on a common panel and electric uses a 12V DC Relay to trigger the 120V AC to element.

You would have to find a 2003/Previous vintage model

OR

Update/change/add DC wiring to replace with NEW Model

WHY do you need to replace current water heater?

Cracked tanks can be replaced/welded
Controls can be replaced

What is issue with current one?

I ran into the same problem, the new 12v switch for LP is now a 4 wire (which requires running new wire) according to the tech from Atwood. So I replaced the tank because it was leaking, then the circuit board went out, lol.

Damn Murphy!
