Thetford 623955

Door Assy-Lower/6'/Panel/Black Frame/Sdl

623955 is the Thetford part number for the door assy-lower/6'/panel/black frame/sdl. It is printed in Thetford’s own parts documentation, which we hold a copy of and link below.

Thetford says to use 638835 instead

Thetford marks this number with “USE 638835” on its own parts list, which is the manufacturer telling you 638835 is what to order now. That instruction comes from the document, not from us, and not from what sellers happen to call the part.

Current number: 638835

Which parts lists carry this number

It appears on the parts lists for 3 different models: N61/N81 Series, N62/N82 Series and N64/N84 Series. A number shared across several models usually means the component was carried over between them, which is useful when the exact list for your model is not the one you can find.

Check the version before you order

This part comes in more than one version, and they differ by colour. Ordering the wrong one gets you a part that is real, correct for the model, and still not the one you need. The other versions on the same documentation are listed below — check yours before ordering.

What we have not checked

We can show you that 623955 is a real Thetford number, what Thetford calls it, and which parts lists carry it. We have not verified that it fits your camper. That depends on your model year, build date and what is actually installed, and we do not publish a fitment claim until we can show it in the manufacturer’s own document.
