Just remove the two leads from hi limit switch and verify across the hi limit switch that you have continuity.

If you don’t have a meter you could.. as a TEST ONLY remove the two leads in the hi limit switch and connect them together to see if furnace will fire...

This is for testing ONLY

Note...if fan isn’t coming on sail switch and hi limit switch have nothing to do with the issue
Fan isn't running so if it isn't the sail or hi switches maybe the delay relay??

I was thinking about TESTING (trust me I understand that one==don't want to burn down the RV!!) by shorting across the switch wires (even got the quick connect spades to make a jumper--for TESTING ONLY).

I did find some info online but like I said haven't been able to get in early enough to test things.....
