Troubleshooting
DO NOT:
• Service the stove with wet hands. The stove is an electrical appliance, which may pose a shock hazard if
handled improperly. Only qualified technicians should deal with possible internal electrical failures.
•
Do not remove from the firebox any screws without penetrating oil lubrication.
WHAT TO DO IF:
1. The stove will not start.
2. The stove will not operate when hot.
3. The exhaust blower will not function normally.
4. Light # 2 on Heat output bar flashing.
5. Auger light flashes but auger motor does not turn at all
6. Light # 4 on Heat output bar flashing.
7. The convection blower will not function normally.
8. Igniter- the pellets will not light.
9. Control settings (Heat Level) has no effect on the fire.
10. The stove keeps going out.
*NOTE: All troubleshooting procedures should be carried out by qualified technicians or installers.
1. The stove will not start.
• Make sure the stove is plugged in and the wall outlet is supplying power.
•
If the Control Board has been placed in the ON /OFF thermostat mode, then turn the thermostat up to call
for heat.
• Check the Heat Level Indicator. - If the # 2 light is flashing (see the # 2 light is flashing)
•
Check the fuse on the circuit board.
• If the unit still does not start, contact your local service dealer for service.
2. The stove will not operate when hot.
• Check the Heat Level Indicator if a fire is not detected, or if the fire has gone out the #3 light will flash
because the Exhaust Temperature Sensor’s contacts have opened.
• Check the hopper for fuel.
•
Incorrect air damper setting. - Excessive air may consume the fire too quickly before the next drop of
fuel, leaving completely unburned fuel in the burn pot liner. - Insufficient air will cause build up, further
restricting the air flow through the Burn Pot Liner. This in turn will cause the fuel to burn cold and very
slowly. Fuel may build up and smother the fire. In this case clean the burn pot. (NOTE: unit may require a
change to the vent system or installation of fresh air to correct Air to Fuel ratio problems).
•
Combustion Blower failure. - The Combustion Blower is not turning fast enough to generate the proper
vacuum in the fire box. Visual Check – is the blower motor turning.
•
Check the Exhaust Blower voltage across the blower wires (>=114V on #5 setting and >= 82V on #1
setting). – Replace the Circuit Board if the Voltage reading is less than 82 V. with a line voltage >114 V AC.
•
Check 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 fire).
If the motor fails to reach a 0.10” W.C. readings, then replace the Combustion Blower.
3. The exhaust motor will not function normally.
• Open the left side access panel; check all connections against the wiring diagram.
• See “2. The stove will not operate when hot.” section.
4. Light # 2 on Heat output bar flashing. (The Vacuum Switch contacts have opened for more than 15 sec.)
•
Pinch, break or clear blockage in Vacuum Hose - Check hose for pinch points or damage, replace or re-route
as required. Blow out Vacuum Hose
