Hello there,
i have a forest river, sandpiper 2004, fifth wheel. most everything on board has been upgraded or replaced over the years other than the suburban furnace that sees a fair amount of use in the winter. i've spent countless hours checking and rechecking, and from what i understand, the furnace tends to be a pretty straightforward appliance in terms of the order of steps, and checks so i think ive eliminated everything other than the following.
one cold day recently, out of nowhere it sounded like something had suddenly obstructed ther fan, or blower, of the furnace. it sounded like a fan being forcefully stopped in motion, some screeching, and then, silence, it stopped.
So at this point everything looks good until the blower would normally turn on, but nothing from there or beyond. so the thermostat gets set, i hear the clicking from above, theres a fan sound from my cpverter sending the power, and usuallyn at this point i will hear the clicking a couople times then the converter fan stops and nothing.
take the furnace out and immediatly i can tell, that the blower opr fan which shoulod spin or move freely...doesnt, its siezed to say the very least, i cannot physically force it to rotate. so i thought i was heading in a pretty obvious direction and from what ive read generally its an obstruction... suchas a rodent etc etc. but theres nothing in there. i cannot see anything that would cause the siezecd state of the motor.
so i guess my question is, once i have the furnace ourt and disconnected, where should i go from there to troubleshoot what the problem could be. can the motor quit like this and also just sieze firmly, i mean so firmly i cannot forcefully rotate it. should i proceed to remove the shell and check further inside, any suggestions would be appreciated.
just to add im aware of the sail switch, the fuse, propane flow is sufficient at the panel etc etc, even though things like the sail switch and igniter should happen post blower, they all check out.
thanks alopt ahead of time i really appreciate any sugggestions
