Suburban Furnace - Blower Motor Failure...AGAIN

We're having the furnace blower motor in our 2008 3670RL replaced for the second time today. I'm very disappointed in the Suburban furnace. The original motor was replaced last January. Here we are a year and a few days later & we're doing it again. This must be a fluke because if it were happening to many others I think I'd have seen more about this on this forum. Or maybe most others are smart enough to go where it's warm in the winter. Either way I hope we have better luck with the furnace in our 2011 3585RL.

Fortunately, we have not had a problem with ours. It gets used a lot, mostly in the beginning and end of our summer season. I'd be curious to know why the second one failed, though.

I think the first motor was a bearing failure. When it first started failing they got it going by giving the squirrel cage a little push & it would spool up & spin fast enough to actuate the sail switch & work okay. That worked for a few weeks but we knew we were near the end of it's life.

For the second motor, it starts & spins on its own but not fast enough to actuate the sail switch. The repairman said he thought this failure had to do with the brushes. Beyond that, I have no idea.
