1998 Heil gas furnace vibration in blower motor wheel
This is a Heil gas (propane) furnace model # pgad42d1k5
My previous post concerned the ignition pilot flame not working after hvac tech installed new honeywell smart valve, new ignition, new transformer and new circuit board. After a 2nd tech fixed more issues, harness wiring and cleaning ignition tubing orifice and resetting propane pressure to ignitor the furnace works but now has a vibration and noise. The 2nd tech said that there is a vibration in the blower motor wheel. The smart valve and gas tubing is also visibly vibrating. I had not heard this noise before and thus have no idea how this came about.
Is this just coincidental? The 2nd tech said the circuit board that was replaced controls the fan. Is this the blower? Will this wear out the blower bearings?
I am assuming the only thing to do is to remove the top from this combination Heil gas furnace and remove the squirrel cage? Plan to do this myself.
Would appreciate some comments ... Thanks
