Furnace problems (fan Wheel shattered)
I have a 2012 40' Sierra by Forest River and the fan wheel shattered last night when I turned it on. I have ran it a couple of times already this year and it worked fine.
Basically what happened last night was that I had it running and it was running well for how ever long and then it cut off (possibly cut off because it reached the temp that the thermostat was set to) then cut back on for a brief period and was really loud and cut itself off. Then it didn't start back up for a long time and I thought well that is strange it should have com back on by now since it was starting to get chilly at that point. So I got it to come back on and it was real loud and then I heard a noise (fan wheel shattering) and then I cut it off. I opened the cover to it and there are parts of the wheel everywhere. This is one of those I think they call them "suburban" furnaces that are mounted under the stove.
Has anyone ever replaced the fan wheel on one of these? do you have to pull the whole furnace out and how hard is that to do?
Also, if it is possible to pull the furnace out rather easily, is it normal for just the fan wheel to go out or does that mean there is a bigger issue as well?
