Dometic Water Heater Dual Switch Panel | 91230 | Gas+Electric | 12V

Control both the gas AND electric sides of your Atwood/Dometic gas-electric RV water heater from inside your RV with the Dometic 91230 Dual 12V Switch Panel. This genuine Dometic OEM dual-switch wall panel lets you independently activate the gas burner OR the electric heating element (or both) from a convenient indoor location — without having to step outside to the water heater compartment. Conserve propane, manage shore power loads, and monitor operation at a glance. The right add-on (or replacement) for owners of Atwood/Dometic LP gas-electric water heaters who want full indoor control of their hot water system.

Dual-Switch Design — Independent Gas AND Electric Control

The 91230 features two independent switches on a single wall panel — letting you control each heating mode separately:

• Gas switch — activates the propane burner side of the water heater
• Electric switch — activates the electric heating element side of the water heater
• Run either independently or together based on your immediate needs and available power sources

That flexibility is meaningful for gas-electric water heaters because each heating mode has different real-world advantages:

• Electric only when on shore power — saves propane, no combustion noise or fumes
• Gas only when boondocking or off-grid — no electrical load on your battery system
• Both together for fastest heat recovery when you need hot water immediately

For Atwood / Dometic LP Gas-Electric Water Heaters

The 91230 is designed for use with Atwood and Dometic LP gas-electric water heaters — including modern models and older versions. Compatible with models such as:

• WH-6GEA
• G6AA-10E
• GC10A-4E
• Other Atwood/Dometic gas-electric water heaters across the G/GC/GCH/GH series

Verify your existing water heater model on the manufacturer label before ordering — the 91230 is designed for gas-electric variants and is not the correct switch for gas-only water heaters.

What This Switch Does

The 91230 is the user-facing wall control for your water heater:

• Activates the gas burner when the gas switch is on
• Activates the electric element when the electric switch is on
• Can run both modes simultaneously for fastest recovery
• Convenient indoor activation \u2014 no need to walk outside to the water heater compartment
• Conserve propane by activating only when needed
• Manage shore power loads by toggling electric heating on/off based on what other appliances are drawing

Real-World Benefits

Why RVers choose to add (or replace) a dual switch panel:

• Energy savings \u2014 only heat water when you actually need it rather than maintaining hot water continuously
• Source flexibility \u2014 use electric when on shore power, gas when boondocking, both together when you need rapid recovery
• Convenient activation \u2014 turn on the water heater while in the bathroom getting ready to shower, rather than walking outside to the unit
• Boondocking-friendly \u2014 propane conservation matters when you're off-grid for extended periods
• Shore power management \u2014 toggle electric heating off when running other high-draw appliances to avoid tripping campground pedestals
• Replacing a failed switch \u2014 restore the indoor control capability when the original panel has failed

Common Failure Symptoms

Common reasons to replace the wall power switch:

• One or both switches are unresponsive \u2014 pressing doesn't activate the corresponding heating mode
• Intermittent operation \u2014 works sometimes, doesn't other times
• Switches feel loose, sticky, or stuck
• Visible damage \u2014 cracks, broken interface, or wear
• Discolored or yellowed panel beyond cleaning
• Original switch panel is missing from the installation

Before assuming the switch has failed, rule out simpler issues \u2014 wiring connections, power supply, fuses, water heater electrical condition \u2014 since these can mimic switch failure symptoms.

White Wall-Mount Design

The 91230 features a clean white finish for clean integration into RV interior walls. Standard screw-on wall-mount installation \u2014 mounting hardware is NOT included (use the existing mounting hardware from your old switch, or standard wall-mounting screws appropriate for your wall material).

12V DC Operation

The 91230 operates on 12V DC \u2014 standard RV electrical, no special inverter or AC power required. Compatible with the wiring already in place on existing Atwood/Dometic gas-electric water heater installations.

\u26a0\ufe0f Professional Installation Recommended

Water heater dual switch panel installation involves working with the RV's 12V DC electrical system and water heater control wiring. Improper wiring can result in water heater operation issues, switch damage, or electrical faults \u2014 particularly with dual-circuit gas+electric water heaters that have multiple control circuits. Installation should be performed by a qualified RV service technician for best results.
