Troubleshooting
√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 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 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 120°F (49°C) temperature sensor. If the stove operates replace the 120°F (49°C) sensor.
3. The exhaust motor will not function normally
√Open the left side panel, check all connections against the “WIRING DIAGRAM” in this manual.
√Thoroughly check for broken wires or connections.
√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, check the exhaust potentiometer in the
√Check all wires for continuity.
√Replace the exhaust motor phase control (speed control module).
√Contact your local dealer for service.
4. The convection blower will not function normally
√Check all the connections between the controller, switch, and the convection blower against the “WIRING DIAGRAM” in this manual.
√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 fire wall) 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,
