Our family has a 10 year old G32V and this heating season I could tell that the venter motor was too noisy. However the temperature of it seems fine and the amp draw is fine also. This leads me to believe that I have a bit of time before it needs to be replaced. Of course I would like to know of the approximate price of this 'motor' and the installation cost. (By chance can someone recommend a LENNOX dealer or HVAC company in the Greater Toronto Area?)
See if it's easy to separate the motor part from the impeller part of the vent assembly. Possible, if you can get the manufacturer and model of the motor you can buy just that part. You can also try a few drops of 50 weight motor oil run down the shaft into the bearings.
