Identify Suburban RV Water Heater Doors by MPN, Tank & Corner Style
If a Suburban heater door has been lost, rusted or bent, you need more than a door with the right colour. Find the model identification on the heater, note the style of the original exterior frame, and compare the complete manufacturer part number. This guide separates SW storage-tank doors from the SAW6 direct-fit family so you can identify a matching replacement.
Look at the heater first, not just the door
Check the model plateLook for SW4, SW6, SW10, SW12, SW16 or a SAW6D/DE/DEL family model. A similar door does not prove the heater model.
Note the exterior frameIs the original door flush against the surround, or does it have rounded corners? Record the existing frame and latch arrangement.
Read the full MPNPart numbers differ by capacity and finish. Even two white doors may be different sizes or shades.
Recognize the exterior door style
A rounded outer-door shape and a flush-mounted rectangular door can have different frame requirements. Use these simple shape sketches to describe the original door, not to establish fit from appearance.

Identify the original access door by number
The following numbers and descriptions follow Suburban's water-heater catalog. The door family and capacity are more important than a close colour match.

Matching note: The heater model and installed access frame must be confirmed. The SAW6 direct-fit door family is not the same as the SW storage-tank access doors, even though both may be described as six-gallon.
