Is this an OEM Suburban replacement part?

Yes. We stock OEM Suburban replacement doors built to the original specifications for fit, color match, and venting cutouts. If you also need internal components, see our related 10 gallon RV water heater parts for tank-style Suburban units.

How do I install the replacement door?

Installation is straightforward. Remove the existing door hinge pins or screws, lift the old door off the frame, and set the new door in place using the same hardware. No sealant or gasket work is required for the door itself. Inspect the surrounding flange and seal while the door is off, and if the seal is cracked or compressed, replace it at the same time.

What other Suburban water heater parts should I keep on hand?

Common wear items for Suburban water heaters include the thermostat, thermal fuse, gas valve, anode rod (on tank models), and the access door itself. If you are winterizing the rig, also see our RV winterizing kits to protect the water lines and bypass the heater correctly.
