The stove will not operate when hot

-Unplug the stove, open the left side panel. Jump the two brown leads that are attached to the 120°F (49°C) Exhaust temperature sensor. If the stove operates replace the 120°F (49°C) sensor.

2.The exhaust motor will not function normally

-Open the left side panel, check all connections against the wiring diagram.

-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 directly to the exhaust blower. If the motor does not run, replace the blower.

-If the motor runs, check the exhaust potentiometer in the Dial A Fire. Remove the grey wires from the exhaust motor speed controller and measure the resistance (10 ohms. to 400k ohms). If this range is not present or it is an open circuit Replace the speed controller.

-Check all wires for continuity

-Replace the exhaust motor phase control (speed control module).

3.The convection blower will not function normally

-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 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.Igniter- the pellets will not light

Everything else in the stove operates but the igniter will not light the pellets

-Make sure the burnpot liner is up tight and square to the ignitor tube.

-Check to see if the exhaust blower is operating.

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

-Check the connections at the igniter socket.

-Place a jumper wire between the two leads on the 120°F (49°C) temperature sensor. If the igniter works. Replace the sensor.

-If the igniter does not work. Replace the igniter

NOTE: The igniter should be bright orange in color. If not Replace the igniter.
