Thetford 690862
Spark Electrode
690862 is the Thetford part number for the spark electrode. It is printed in Thetford’s own parts documentation, which we hold a copy of and link below.
Thetford says to use 690877 instead
Thetford marks this number with “USE 690877” on its own parts list, which is the manufacturer telling you 690877 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: 690877

What we have not checked
We can show you that 690862 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 That depends on your model year, build date and what is actually installed, and we do not publish a fitment claim until we can show it in the manufacturer’s own document.
