hi Jerry from pine Meadows hobby farm I have another money saving tip for you guys for those
of you who own RVs you have a propane fired forced air furnace in your RV and that quits
working chances are the brushes wore out in the motor so this episode we're going to remove the
furnace replace the motor and reinstall it so let's start the adventure you'll be working
with gas so you want to make sure you turn off your gas supply my gas supply is located right
here so we make sure both propane cylinders are turned off and it just cuts off the gas
supply and we're going to go ahead and go to the next step at removing the furnace the next step
of removing the furnace is remove this plate that is the exhaust plate on the outside of your fifth
wheel now I'm going to start by removing this metal screw right here with a Philips screwdriver
store it right there for right now and then we go inside and take the the furnace out
and then we'll take it in and put it on my workbench you want to take a wrench
and you want to remove your gas supply just by turning that and then this wire
you have to detach it and this is where it clips and there's a little tab on the side
you press the tab and pull that little tab and now the furnace is disconnected
now we'll just go ahead and take this to the shop put it on the bench and
change that motor out okay we're on the workbench we're going to start
tearing down this furnace and it's really easy there's only two screws keeping the
furnace inside of this box and they're on the bottom and these screws are right here
you just remove these two and now we have to take the furnace out of the box okay
set the Box on the floor we won't get down anymore and we'll put the furnace
right here and we'll be working on this side of the furnace so first of all you
want to remove these two wires here you just unclip them and then you remove this holder
ah
and get those wires out of the way because they're just going to be in your way you
have a red wire down here you're going to unplug this actually services the motor you want unplug
that tap that out of the way and this right here is the other wire that is servicing the motor so
you just want to unplug that carefully now the motors disconnected now we begin the removal of
all of these screws because we've got to take the shroud off to access the little cage fan
inside go ahead and remove both screws on this bracket that holds the shroud
on because this brackets just going to get in your way when you're trying to
maneuver this in and out of there you got one more screw down here
and on the bottom right here you got this little clip I'm just going to pop that little clip off
of there easier said than done there we go just a little metal clip now this is ready to come off
and that's it to the Shroud now we're going to preserve this we're going to pull this off
this is the CL and we're to set that aside now this flywheel has a Allen bolt right down inside
there it's got a I got to have a long enough Allen bolt to be able to our allen wrench to
be able to fit through those fans and loosen that okay now on this housing we've got some
screws we got one right here it's right there I'm going to take that screw off
you got two over here and you're almost done but you have to flip it on its side because you've
got you've got this screw and this screw and then you've got that one right there
and there's one that already came out right there we got to take those off so let's get
those off now okay and this little piece right here slides out but you have to pull this away
and you just twist it right there let's save these those are our seals and then you have
this this is that exhaust pipe set that aside now we're done with the this is the furnace
without the fan so and this is your circuit this thing will go bad eventually so it's real
easy to change out just unclip those wires you got this this wire right here and you got this
igniter wire and these two wires just it's held in by two screws pull that out take it down to
the RV repair place or order it online and step it back in and you're good to go so we're going
to go ahead and change the motor out in this unit but we got to get the motor off so we've
got this screw right here we have that screw right there and that screw right there but
before we can take those on we have to remove this little allen screw that's down in there so
let's remove that at this time since I don't have the right talon ranch I've got an Allen
socket here okay that fits and then we have to yeah Jerry wait this knocked on it I use
a little tiny a little teeny tiny crescent wrench and we're just going to loosen that
and pull the fan out and that's the cage fan or scroll fan and remember which way you pulled
it out because it has to go in that same way otherwise you'll be sucking instead of blowing air
and I don't think you want to do that so put that back in my tool box for now and we're going to go
ahead and remove this I have a special screwdriver that will do exactly something like this
make note that this is exhaust comes out right next to your your air switch limit
switch so we're going to pull that right on out of there and there's your housing to
your squirrel fan your squirrel cage I'm going to set that aside now we have the
motor and you've got you've got this screw and that screw loosen so I'm going to get
a bigger screwdriver okay we're just going to loosen them when I've got taken completely off
you're just going to loosen them and now that they're loose then we're going to go ahead and
shut now make note where the wires on this motor come out of this you want to make sure you have
the wires come out in the same spot and the motors position in the same spot this is a
double shaft motor so you want to make sure you have the right shaft on the right side so
be careful when you're taking them off okay we go ahead and this is the fan shroud okay
we're going to tap at that aside now we're down to the motor and we can go ahead and find the right
one that goes to that one I don't think I have an Allen wrench to fit that yes I do this one
but it's not not long enough to go back down in there okay let's see if
I tight out loosen it it enough to come off there we go holy Sh
meal okay all right this motors out so that's removing motor from the
furnace I want to thank you for joining me on this section for repairing the RV
