Turn the furnace on and blower engages, blows cold for 30 seconds during the purge / pre-ignition cycle and cuts off.
Have checked / replaced both the sail switch and hi-limit switch and same symptoms.
I can manually engage the sail switch after switching to Heat Gas on the thermostat and the blower starts to which everything will fire up but once I let my finger off of the switch it falls back to it's original position and the unit essentially cuts off after a minute or two of run time.
Have checked all of the vents and there is no blockage, etc.
Am on 50a shore power, so no issues there.
Have checked propane, all is full, flow is fine.
I feel like for some reason the blower fan isn't producing enough output to engage the sail switch, but output when running for startup produces sufficient air inside coming through the vents so not sure.
Have a Dinosaur 50 PINS Plus board on order and waiting for it to come in to change next.
Completely stumped as this point-
Thoughts?
