Dinosaur Board..........(YES different then OEM)
1) IF fan doesn't come on AND GREEN Light is ON then 'sail switch' is stuck closed.
(Must be open before fan runs and closes it)
2) Fan runs and GREEN light does NOT come on then problem with 'sail switch/high limit switch' circuit......either sail switch is not closing or high limit is stuck closed.
You have a stuck closed sail switch....issue #1
