Troubleshooting

8. The dial-a-fire has no effect on the fire.

wMake sure all connections to the timer control module are secure.

wPerform a resistance test to the dial-a-fire potentiometer by placing the two (2) test leads from a multimeter into the leads of the potentiometer. The potentiometer should have a range of 68KΩ to approximately 850 KΩ (± 10%).

Potentiometer Readings:

Full counter-clockwise (switched off) = open circuit, overload or infinite resistance Low fire ...............................800 KΩ to 900 KΩ

High fire ..............................68 KΩ to 82 KΩ

If the range is not close or does not vary then replace the potentiometer.

9. The stove will not shut off.

wMake sure the AUTO/MANUAL switch is in the AUTO position.

wCheck the connections to the 120°F (49°C) temperature sensor and AUTO/MANUAL switch against the wiring diagram.

wCheck the 120°F (49°C) temperature sensor by removing one of the brown wires from the sensor. The unit should shut down right away as long as the switch is in the AUTO position. If the stove shuts down, replace the 120°F (49°C) sensor. If the stove does not shut down, test the switch.

wTo test the switch, the stove must be cold. With one of the brown wires removed from the 120°F (49°C) temperature sensor, remove the grey wire from the switch, the stove should shut down. If this is the result then replace the AUTO/MANUAL switch.

wIf the stove still does not shut off, replace the wiring harness.

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 fire is going out before the stove shuts off.

wCheck to see that the Slider / Damper is in the correct position.

wTurn the Dial-a-Fire up slightly (poor quality pellets will require slightly higher settings).

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.

wAdjust the Slider / Damper.

wCheck to see if the stove needs a more complete cleaning.

wDid the power go out?

wContact your local Dealer for service.

wTurn the Dial-a-Fire up slightly (poor quality pellets will require slightly higher settings).

If the stove goes out and there are no pellets in the liner, the auger is stopping.

wSee “The auger motor will not function normally” and “The exhaust blower will not function normally.”
