Troubleshooting

●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 Magnehelic Gauge (readings must be above 0.10” W.C. on low fire).

Note: If the motor fails to reach a 0.10” W.C. reading, then replace the Combustion Blower.

●Poor Quality Fuel – Insufficient energy in the fuel to produce enough heat to keep the stove burning or operational.

●Exhaust Temperature Sensor failure – Bypass sensor located on Exhaust Blower. If stove now operates properly, the unit may require cleaning or a new sensor. Contact your local dealer for service.

●The unit may require cleaning. Contact your local dealer for service.

●Unplug the stove, open the left side panel. Jump the two (2) brown leads that are attached to the 140°F (60°C) temperature sensor. If the stove operates replace the 140°F (60°C) sensor.

3. The exhaust motor will not function normally.

●Open the left side access panel; check all connections against the wiring diagram.

●If all the connections are verified and the exhaust blower does not function at all, tap lightly on the exhaust blower’s motor end cap, this may loosen a tight motor.

●Apply 115 V AC directly to the exhaust blower. If the motor does not run, replace the blower.

●If the motor runs, have your dealer check the harness.

●See “2. The stove will not operate when hot.” section.

●Contact your local dealer for service.

4.The convection blower will not function normally. ● Clean all grill openings at the back and below unit.

●Check all the connections between the controller, switch, and the convection blower against the wiring diagram.

●If the convection motor will not run, apply 115 V AC to the motor directly. If the motor runs, replace the fan controller. If the motor does not run, the convection blower has failed. Replace the blower.

●If the convection blower runs on high at all times (no control with the fan controller), check the connections from the 160°F (71°C) sensor (located on the upper left side of the firewall) and convection fan controller to the blower. Disconnect one of the wires from the sensor; if control of the convection blower returns to the fan controller, replace the sensor.

●If the motor is still on high, re-connect the sensor and replace the convection fan controller.

5. Ignitor - Everything else in the stove operates but the ignitor will not light the pellets.

●Check the burn pot liner placement. Make sure the burn pot liner is up tight and square to the ignitor tube (by pushing the burn pot back against the ignitor tube).

●Check all the electrical connections on the 120°F (49°C) temperature sensor located on the exhaust channel.

●Place a jumper wire between the two leads on the 120°F (49°C) temperature sensor. If the ignitor works, replace the sensor.

●Check to see if the exhaust blower is operating. If not, contact your local dealer for service.

●If the ignitor does not work, replace it.

NOTE: The ignitor should be bright orange in color. If not, replace the ignitor.
