RV Water Heater Parts Diagram FAQ

How do I find the correct RV water heater parts diagram?

Start by locating the full model number on the RV water heater rating label or data plate. Then use the jump links or page search feature to find the matching Atwood, Dometic, Suburban or Girard model.

Where is the model number on an RV water heater?

The model number is usually listed on a rating label near the exterior access area, tank jacket, or water heater cabinet. Always match the complete model number, and check any serial number notes, before ordering replacement parts.

Can I order RV water heater parts by OEM part number?

Yes. After opening the correct parts diagram, search the OEM manufacturer part number shown in the parts list. This is the best way to identify compatible control boards, gas valves, burner assemblies, thermostats, heating elements, relief valves, doors and service parts.

Are Atwood and Dometic RV water heater parts interchangeable?

Some Atwood water heater models later appear under the Dometic name, but compatibility still depends on the exact model and OEM part number. Always compare your full model number, serial notes and existing part number before ordering.

Do RV water heater access doors come with replacement water heaters?

Many RV water heater access doors, trim pieces and exterior components are model-specific and may be sold separately. Always check the listing description and compare your existing water heater before ordering.

Where can I buy RV water heater parts after finding the part number?

Once you identify the OEM part number, search it directly on the site or browse the New RV Water Heater Parts, RV Water Heaters and New RV Tankless Water Heaters collections.
