Avalon 900 PS Pellet Stove Problem

[Harman&Avalon]

We've had this pellet stove for about 5 years. The end of the last heating season we noticed Black soot coating the walls of the burning chamber. The burning pot was filled with black ash (klinkers?) too. So this year my husband replaced the combustion blower. But that didn't fix it. Any ideas of what could be causing this?

Thanks for your help

Troubleshooting an Avalon 900 PS Pellet Stove

Pellet stoves are used as an alternative to heating a home with a furnace or a wood stove. One pellet stove that is intended for home use is the Arbor PS 900 that is manufactured by Avalon. This type of stove is a freestanding unit that will require troubleshooting when problems begin to occur.
Difficulty: Moderate
Instructions

Not Enough Air
1.
1

Open the door to the unit and pull out the restrictor.
2.
2

Observe the flame and see if it begins to flare up and become active. An active flame will keep the hole in the firepot clean. Plugged holes can restrict air flow.
3.
3

Turn off the fan and wait for the stove to cool. Clean out all of the ash and debris that is in the firebox.
4.
4

Repeat steps 1 and 2 to see if the stove now gets enough air to get an active flame.
Fault LIght Comes On
5.
1

Open the door to the stove and see if it is out of pellets. Turn off the unit and add more pellets to the stove. Turn on the unit to see if the fault light goes away.
6.
2

Turn off the unit and then turn it back on. If the fault light comes on for only a split second it is part of the normal startup operation of the unit.
7.
3

Turn on the unit and see if it is starting to get warm. The fault light will come on if the heater is not warming after startup.
8.
4

Turn the mode switch on the stove to the “Off†position and then turn off the stove. Turn the stove back on to reset the fault light.

.....Any ideas of what could be causing this?

Thanks for your help

IMO, sounds very much like a very dirty stove inside restricting airflow.....that makes the air/fuel mixture much too "rich" and black soot occurs....same thing happens in a car when air/fuel mixture gets too much fuel....black tailpipe.

The stove needs to be taken apart as far as possible and cleaned, along with ALL of the exhaust pipe from the stove to the cap.

I believe hearth.com member Wood Heat Stoves has a service manual for that stove.

You might want to PM him and ask.

Thank you everyone!! We're taking it apart stem to stern. And check out the chimney too.
