Austroflamm lazy flame

[65malibu]

Hi all, new to this forum.
I'm having a lazy flame / clinker problem with my 1995 Integra insert. It just doesn't seem to be getting enough combustion air lately. I've got a manual and have checked the voltages on the combustion blower between terminals 3 +5 during operation. They are: low = 40v, high = 119v. I had Joe Narduzzi repair the circuit board and check the user panel 2 years ago and I replaced the combustion blower the same year. I haven't done the cold run test to check the air sensor yet, but that has been replaced a few years ago as well. The stove is cleaned every weekend including the rear chamber. ( It is in a see through fireplace, so there is easy access). Stove pipe was just cleaned. I haven't re-gasketed it in a while, but the door closes and latches tightly. Any ideas why the voltage is so high when in the high position? The manual calls for 52v. I'm burning La Crete pellets

I would call Joe and see what he says. It would seem the motor is the problem,BUT that actually is a rare event, it is usually the capacitor for the motor that gets weak. Other pellet stoves have used this motor,also. AND, if my memory is correct, a capacitor from a Ravelli will work,they are spliced in, not permanent crimp like an Austoflamm. But there are different ones, and it might even have been a different manufacturer. Joe might remember.

I did replace the motor and capacitor in 2019 and never ran the stove in 2020, so probably 3 1/2 tons of pellets have been burned. Joe didn't think it was anything he touched that would create the problem

Joe might know something from the voltages. You are puling out the interior panels and cleaning the 4 small holes behind the heat tubes,I hope.

Yes, everytime I clean the stove.
