Identify Dometic & Atwood Water Heater Doors by MPN and Model
Is the access door on your RV's water heater damaged or missing? A similar-looking panel may not be a suitable replacement. The heater's model plate, original frame and latch arrangement are the best starting points. These part-number comparisons help you identify doors listed for older Atwood water heaters and the later Dometic WH-series units.
Identify the heater behind the access panel
Check the complete modelLook for the data plate and record all the characters. WH-6GEA and older GC6AA models need different identification checks even though both have a six-gallon tank.
Describe the original doorNote the outside opening, door corners, mounting flange and centre or corner latch arrangement. If the heater was replaced, the opening may have been adapted.
Compare the exact replacement numberUse the part-number chart below to identify the correct door or kit category. Confirm the model and installation hardware before ordering.
Understanding the two WH-series door sizes
WH-6GA / WH-6GEA / WH-9GEA
All three are in the smaller door family. WH-9GEA is a six-gallon physical tank with a higher effective hot-water capacity, not a nine-gallon physical tank.
WH-10GEA / WH-16GEA
This family uses a ten-gallon physical tank. The sixteen-gallon designation refers to effective hot-water output, not a sixteen-gallon tank shell.
A door from an old Atwood G6A or GC10A appliance should not automatically be treated as the same part as a door for a WH-series heater. Dometic provides separate legacy and newer door part numbers.

When using a retrofit kit: 94946 and 94951 are catalogued as door-conversion kits with adapter plates for certain rectangular, centre-latch installations. The presence of adapter plates does not guarantee that either kit will fit any old opening. Check the new heater installation documents and the wall dimensions before ordering.

Current smaller WH-series doors
WH-6GA, WH-6GEA and WH-9GEA use the 6-gallon physical-tank door family.
Conversion kits for older rectangular door openings
Compare adapter plates and mounting requirements rather than treating these as ordinary replacement panels.
Current larger WH-series doors
Dometic service-kit doors for the WH-10GEA and WH-16GEA family.
Older Atwood access doors
For older Atwood water heaters, verify exact model, exterior opening and existing latch/door arrangement.
Common door-replacement questions
Is WH-9GEA larger than WH-6GEA?
No. WH-9GEA has a six-gallon physical tank and is part of the smaller WH access-door family. Its higher nominal hot-water rating is an effective-capacity designation.
Will a door from a six-gallon Atwood heater fit a WH-6GEA?
Not necessarily. The original frame and cutout can differ from the newer heater design. Some replacement installations need adapter components or a conversion kit. Use the manufacturer installation guide to confirm the opening.
Are 95500 and 95505 different sizes?
Dometic lists these as different colour/service-kit options within the WH-10GEA and WH-16GEA family. Their part numbers should not be swapped without confirming the desired colour and kit contents.
Use a water-heater parts diagram for deeper identification
See the WH-series model and parts finder, WH-6GEA diagram, WH-9GEA diagram or WH-10GEA parts list. For older appliances, compare the Atwood GC6AA10E reference. The complete heater model index covers additional models.
Confirm final fitment using the relevant Dometic installation instructions and original door or heater model. Exterior vents must remain unobstructed, and LP appliances should be serviced according to the manufacturer's safety directions.
