Harman Advance-2 Distro Blower

[Rick5472]

I am noticing that my Harman Advance-2's distribution blower seems to be at one constant speed with the mode selector dial set to the high position in room temp mode. The room temp is staying at the set temp. It used to throttle the distribution motor up and down depending on the room temp. Seems to be constant now. Any thoughts?

Have you turned it to stove temp to see if it works correctly?

Same thing in stove temp mode.

It seems like the blower speed is on the high speed in both room temp and stove temp modes. The fire throttles down in room temp mode but the blower speed remains constant. Can't tell if I have a problem with my control board, blower or something else.
