Hey all, I have a problem with my newly installed Newmac cl86 wood/oil furnace.
Right after we installed it, we had a problem where the blowers sounded like they had marbles in it, turned out it was slightly off kilter, but now is dead on balls level.
Last night (this morning, actually) out of nowhere, it started making this "grinding gears" sound. The blowers would come on and sound normally, then the "marbles" sound would start building up gradually and after a few seconds sounds like grinding gears and would start the sequence of sounds over until they shut off. I went down to investigate, but being half asleep and not knowing much about hvac anyways, the only thing I did was tighten up the drive belt (which seemed loose). I checked, and it is still level.
the next few times it came on it was okay, sounded normal. After about a half hour, it started again, first with "marbles" then "grinding gears". Finally, it just had a slight "marbles" sound to it.
Any Ideas?
BTW, for what its worth the firnace was bought new in august and installed by my brother in law, who went to college for hvac, but is pretty new to the game.
