I need some help, please....three year old Castile making a ticking (chattering) noise at start up

[Augmister]

I did a stove fire box cleaning yesterday. Dropped and cleaned the exchanger tube baffle (top of fire box) and pulled the rear baffles to get all the dust out. Vacuumed out the dust in that fan behind the right baffle. When I restarted the stove by turning up the thermostat, after the "click" (when the stove goes on and the red light goes on- demand for heat) I normally hear what sounds like a slow rpm whir of a start up fan (not the fan blowers when the box is up to temp and the hot air comes out through the tubes in front). Well, that whirring (which is pretty quiet) now has some "chatter." The chatter is drowned out by the other stove noises but does not go away.
Does anybody know what is wrong? I get antsy when things are not right with the stove and this chattering noise means to me something has changed. Ideas? Thanks!

Sounds like your exhaust blower may need cleaned/checked out.

During cleaning did you notice the fan fins behind the right side baffle plate? That is your combustion blower. Its possible you partially cleaned it and now its unbalanced, or maybe during cleaning a bunch of stuff fell in it that you did not vacuum up.

I noticed that if you put the right rear baffle on the left side and vice versa you get a clinking noise during start up. Make sure the "bricks" line up.
