TROUBLESHOOTING
TROUBLESHOOTING
9Blocked exhaust / venting system - Have stove and venting cleaned and inspected.
9Severe negative pressure in area where unit is installed - Check the operation by opening a window, does this solve the problem? If it does, install
fresh air intake to unit or room. Venting system may require vertical section to move termination into a low pressure zone.
9Vacuum Switch failure - Bypass the vacuum switch, if this corrects the problem check for above problems before replacing the Vacuum Switch.
9Damage to gray wires between Circuit Board and Vacuum Switch - Inspect wires and connectors
9Combustion Blower failure - The Combustion Blower is not turning fast enough to generate the proper vacuum in the Exhaust Channel.
Visual Check; is the blower motor turning? Check the Exhaust Blower voltage across the blower wires (>=114 V on #5 setting and >= 82 V on #1
setting). – Replace the Circuit Board if the Voltage reading is less than 82 V. with a line voltage >114 V AC.
9Check Vacuum levels in the exhaust channel by bypassing the vacuum switch, then remove the Vacuum hose from Vacuum Switch. Check exhaust
vacuum readings by placing the open end of the Vacuum Hose on a Magnahelic Gauge. (readings must be above .10” W.C. on low fi re).
If the motor fails to reach a 0.10” W.C. readings, then replace the Combustion Blower
To reset Circuit Board after a trouble code - push the ON/OFF button
5. Auger light fl ashes but auger motor does not turn at all.
9If the Auger gear box does not turn but the motor’s armature does try to spin then the auger is jammed. – Try to break apart jam by poking at the jam
through the drop tube. If this fails then empty the hopper and remove the Auger Cover **Remember to re-seal the cover after installation**
9Check the fuse on the circuit board.
6. The 200 °F ( 93 °C) high limit temperature sensor has tripped.
9Reset sensor and determine cause – was it Convection Blower failure or 160 °F ( 71 °C) Temperature Sensor failure? Bypass the 160 °F ( 71 °C)
sensor, does the Convection blower come on high if not replace the blower? If yes, replace sensor (located on the left side of the fi rewall).
9Check the fuse on the circuit board.
7. The convection blower will not function normally.
9Clean all grill openings at the back and below unit .
9Press the fan button; does the fan come on? Press again to verify that the blower turns on; if, not contact your local dealer for service.
8. Ignitor- the pellets will not light.
9Everything else in the stove operates but the ignitor will not light the pellets.
9Make sure the burn pot liner is up tight and square to the ignitor tube by pushing the burn pot back against the ignitor tube.
9Check to see if the exhaust blower is operating. If not, contact your local dealer for service.
9Check the fuse on the circuit board.
NOTE: The ignitor should be bright orange in color. If not replace the ignitor.
9. Control settings (Heat Level) has no effect on the fi re.
NOTE: If the system light is fl ashing the Control Board has complete control of the unit. When the units system light becomes solid then control of the
unit is given back to the operator.
9If there is no control of the Heat Level button make sure the thermostat is calling for heat.
9Call your local dealer for service.
10. The stove keeps going out.
If the stove goes out and leaves fresh unburned pellets or cigarette-like ashes in the burn pot liner, the fi re is going out before the stove shuts off.
9Check to see that the Slider / Damper is in the correct position.
9Turn the Heat Level up slightly (poor quality pellets will require slightly higher settings).
9Set the auger trim till the #1 and #5 lights are illuminated.
If the stove goes out and there are partially burned pellets left in the burn pot liner, the stove has shut down due to a lack of air, exhaust temperature,
or power failure.
9Adjust the Slider / Damper.
9Check to see if the stove needs a more complete cleaning.
9Turn the Heat Level up slightly (poor quality pellets will require slightly higher settings).
9Did the power go out?
9Contact your local Dealer for service.
