High Pitched squeal. Englander PDV

[kdp7462]

Hi All

Earlier this week I pulled both blowers from the stove and really went through a good cleaning getting ready for the winter. Stove has run awesome the last 3 days. Anyway, I have had it running since about 4 this afternoon, but in the last hour or so, it has a high pitched squeal coming out of the exhaust blower area. It only seems to squeel when it is fired up. I have turned it off and let flames go out, and it stops. If I turn it back on, once the flames get going I get the squeal again. Any idea why this would be happening?

heat could be affecting the bearing on the inside of the blower motor. how old is the stove?

Thanks Mike!
I figured that maybe the root cause, so I let the stove go cool(room blower off). I then restarted it, and it has been fine since. The stove is going into its 4th season. Should I be worried that I will need to be replacing the blower this year? I just cleaned it and the inside looks good.

its a possibility, ive seen em squeal for a while and stop and run for years , and ive seen em squeal and stop and lock up soon after. so theres no "set in stone" answer for this. i'd consider maybe ordering one just in case , if the blower keps on trucking put the new one on the shelf , eventually any motor will wear out and that thing has a pretty tough life to lead. the new one wont exactly rot sitting on the shelf either.
