Thetford parts reference
Thetford 623980
Door Gasket
623980 is the Thetford part number for the door gasket. It is printed in Thetford’s own parts documentation, which we hold a copy of and link below.
Thetford says to use 638816 instead
Thetford marks this number with “USE 638816” on its own parts list, which is the manufacturer telling you 638816 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: 638816
