Trouble-Shooting; Troubleshooting - Harman Stove Company Accentra Owner's Manual

FEEDER DOES NOT FEED
1. No pellets in hopper.
2. Firebox draft may be too low for low draft pressure
switch in feeder circuit to operate. Check for closed
doors, loose or missing gasket on doors or hopper lid,
faulty pressure switch.
3. Feed motor will not run until ESP
senses 165 deg. F. Maybe you did not put
enough pellets in the burn pot before lighting the fire.
4. Something is restricting flow in the hopper or caus-
ing the slide plate to stick.
5. Feed motor has failed.
PARTIALLY BURNED PELLETS
1. Feed rate too high.
2. Draft too low. (Check burn pot clean out slide and
door gasket).
3. Burn pot or heat exchanger tubes may need to be
cleaned.
4. Combination of all the above.
5. #6 status blink: A 6 blink control board status indi-
cation is caused by poor or incomplete combustion.
The Advance Automatic Ignition circuit board has the
ability to track the combustion through feed settings
and ESP temperatures. When the control board has
calculated poor or incomplete combustion it will shut
down the unit as a safety feature. (Poor or incomplete
combustion is a contributer of creasote which may
cause a chimney fire)
A 6 blink status may be caused by several things:
1. Blocked or partially blocked flue.
2. Blocked or partially blocked inlet air.
a. backdraft damper on the inlet pipe may be stuck
closed.
b. if outside air is installed the inlet cover may be
blocked.
3. The air chamber under the burnpot may be filled
with fines and small bits of ash.
4. The holes in the burnpot may be getting filled with
ash or carbon buildup.
5. Combustion blower fan blades may need cleaned.
6. Combustion intake assembly not properly latched.
SMOKE SMELL
Seal the vent pipe joints and connection to stove with
silicone.
FIRE HAS GONE OUT

3. Something is restricting fuel flow.
4. Feed motor or draft motor has failed.
5. Power failure or blown fuse.
