Not sure whats going on here. The heater has recently stopped working on the 1, 2, and 3 settings. It still works on the highest setting but it makes this crazy, repetitive, loud sound like something has possibly broken off and is stuck in the way. I am a noobie and have looked around the forum for similar posts to no avail. If anyone has had this issue or has any ideas, I'd appreciate it.

 

Probably needs a new blower motor. Not a very tough job. You should be able to find how to do it by searching the forum. If you find directions that works for you, let me know and I will add it to the helpful hints in the 850 forum.

 

I mean, thats the only logical explanation but I just don't understand why it would still work at all if that were the case. I will check and let you know if I find any useful write-ups.
