Dometic RV Water Heater Doors

Which Dometic water heater door fits the 6-gallon Atwood/Dometic 94010?

The Dometic 94010 door fits 6-gallon Atwood and Dometic water heaters with a cutout of approximately 12-7/8" wide by 12-7/8" tall. Confirm your existing door dimensions and the model number stamped on your water heater (typically GC6AA-10E, GCH6A-10E, or similar) before ordering. If you have a 10-gallon tank instead, see our 10 gallon RV water heater collection for the correct door and tank components.

How do I replace an RV water heater door?

Remove the four corner screws on the existing door frame, disconnect the latch mechanism, and pull the frame away from the sidewall. Clean the old butyl tape residue from the cutout, apply fresh butyl tape to the new door frame, set it into the opening, and reinstall the screws. Most replacements take 20 to 30 minutes. Inspect your gas valve and burner access while the door is off, then keep extras on hand from our RV winterizing kits collection for end-of-season service.

What color and finish options are available?

Dometic water heater doors come in colonial white, polar white, and black. Match the door to your existing exterior panels rather than the rest of your RV trim, since sidewall colors vary by year and model. The 94010 is the black 6-gallon version; colonial white and polar white use different part numbers under the same dimensional spec.

Will a replacement door restore the seal against water intrusion?

Yes, provided you apply fresh butyl tape around the frame flange and torque the screws evenly. The door itself does not seal the tank; it protects the burner and controls from rain and road spray. If you see water staining inside the compartment, inspect the tank flange and surrounding wall for soft spots before installing the new door.
