The blower motor went out on my furnace and needs to be replaced. I need to know how to get it out without having to remove the entire furnace assembly. At one end is a metal "squirrel cage) type blower. Is this blower fan pressed on to the shaft? Or will removing the set screw allow it's removal?

I'll try to get a photo of where the blower mounts to the shaft. If I do have to remove the entire furnace, which was installed in 1998, would a new furnace be worth the price in performance? Are new furnaces any better?

Any suggestions would be appreciated
 
Soaked the shaft with penetrating oil and worked it off with a large screwdriver. Replaced the motor and everything works. Whew! It's been really cold working outside. Now I can crawl inside & get warm
 
Glad you got it ok. I did mine in 2011 and was about to reply when I saw in your follow-up post that the job was done.

I had to pull the furnace on mine - there was no way to get the squirrel cage off the shaft and out through the furnace cause it was on the far side right against the casing. Some models have a bit more room and it can be worked out.
 
To get the black plastic squirrel cage out (the one that surrounds the motor) I removed the electronic  panel which opened up the aft end of the furnace box. Removing my furnace would have been problematic because it's rivited to the RV. I've got no problem drilling & installing rivits but all the tools needed for that part of the were at work. If you click on the link below, you can see in the back end where I removed the panel to get the black squirrel cage out.

The front squirrel cage is metal and is inside the round metal shroud. If I hadn't been able to separate the metal blower from the shaft, I would have gotten the shaft. This is our first RV and we just bought it used back in November and it's been an adventure since. Broken pipes, trying to get the water heater to work, trying to figure out why the propane wouldn't work, pipes freezing and cracking, blower motor going out, pipes freezing and cracking and more pipes freezing and cracking while repairing the blower motor and the broken pipes. Makes you wonder just who's big idea it was to move into an RV and spend the winter in Utah. Should have waited for a job offer in Washington where the winters are milder.

I guess I'll be pulling apart the bathroom cabinet tomorrow to see what broke. Hopefully, it'll be something easy to get to for a change
 
Hi Ho:  It's kind of like the Arkansas traveler and the leaky roof.  Can't fix it in the rain and don't need it when it isn't.  It is really cold here in Utah--highs about 15 to 20 deg.  I needed to replace the brakes on the snowmobile trailer, so against my better judgment I took it to Les Schwab.  Hardly ever do that.  Maybe I'm getting older--or just plain old.  :)
 
Dirk,

I have a number of things that need to be done on the MH before we travel this spring but today is the first day we have broken 40? in a long time and that is not warm enough to do any of the stuff as most if not all of the material should be above at least 65?.  :(
 
40 degrees! We'd be running around in shorts & tee-shirts if go that warm around here!
 
Hi Ho MistWolf:  Noticed that you are in Utah.  We live in Draper.  By the way, if you fill in a little about your coach etc. in your profile folks will be better able to help.  And, it's too cold for me outside, and the air's too yukky.  Where are you located?
 
Haven't checked in for awhile. We're up near Ogden. Weather has warmed up and I've been replacing the PVC tubing with PEX. Next project is to tear into the utility room, rip out the PVC and replace it with PEX and install valves to allow us to run city water and fill our tank from there.

Now that I've collected the tools needed for the job, it's going much easier
