Looking up on how to replace sail switch I have to take the blower cover off, does that sound correct?
Thanks

Sail Switch...newer circuit boards will not allow operation if sail switch is stuck CLOSED
*If yours uses a 'Timed Delay Relay'.....circuit board would not sense/care what position sail switch was in.
Course not knowing what year your RV is and what that Statement in RED means...
Hi Temp Limit Switch would cause what is called 'Limiting' --- burner goes off/back on, off/back on etc fan continues to run
Heat Exchanger overheating...limit switch opens...fan cools HE down/flame ignites...cycle repeats
So NO it is NOT the Limit Switch
Could be sail switch
Could be Thermostat
Could be circuit board 'Pwr' or 'Blw' circuits
Could be could be could be
