Fireplace Blower Motor Running Slow

Have a Quadra-Fire Bodega Bay fireplace insert (wood burning). The electric blower is pumping out much less air than previously. You can now turn the fan speed control all the way up, where in the past it was too noisy and shaky at full speed - you'd have to back it down a bit. I jumped the fan speed control to see if that was the problem - no impact. Brought the fan into the dealer - they say it works fine and is up to spec. Any ideas? What would cause a fan to suddenly run slower at full voltage? It's a typical "squirrel cage? blower common to fireplaces and wood stoves. Thanks,
Steve

Is it really running slower or just moving less air? Could the ducting be restricted? Did you try running it out of its location?

On your speed control you should have an adjustment screw. When you turn the speed control on (clockwise) it will be on high speed. You then turn it back towards off to get the highest rpm's. As you move it clockwise the fan should slow down and all the way clockwise it should be at its slowest. Turn the unit on and turn the speed control all the way clockwise.
There is a hole on the side of the speed control for adjustment purposes. Turn the adjustment screw and slow the fan down but do not go so far as to stop the fan. Now turn the speed control back towards off an see if it increases in rpm's as you like.
