Hi. My Lennox furnace makes a squeaking /whining noise every time when it is powering down and to a certain extent when powering on. I posted a video on youtube:
I replaced the filter and vacuumed around the inducer and blower fan and also lubricated the bearing of the inducer fan with WD40 without resolving the noise issue.
Does anyone know where this noise is coming from and what I could do about it?
