7. The dial-a-fire has no effect on the fire
Make sure all connections to the timer control module are secure.
Perform 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 34 KΩ to 900
KΩ (± 10%).
Potentiometer Readings:
Full counter-clockwise (switched off) = open circuit, overload or infinite resistance
Low fire 800 KΩ to 900 KΩ
High fire 34 KΩ to 40 KΩ
If the range is not close or does not vary then replace the potentiometer.
8. The stove will not shut down
√ Check the connections to the 120°F (49°C) exhaust temperature sensor, start-up switch and the start-
up timer against the “W
IRING
D
IAGRAM
” in this manual.
√ Check the 120°F (49°C) temperature sensor by removing one (1) of the brown wires from the sensor.
The unit should shut down right away as long as the start button was not pressed within fifteen (15)
minutes of this test. If the stove shuts down within fifteen (15) minutes, replace the 120°F (49°C)
sensor. If the stove does not shut down within fifteen (15) minutes, test the switch.
√ To test the switch, the stove must be cold. Pull the plug, then plug the stove back in. If it fails to start,
replace the switch.
9. 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 120°F (49°C) temperature sensor shuts the stove off.
- Check to see that the slider is in the correct position.
- Turn 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 shuts
down due to a lack of air, exhaust temperature or power failure.
- Adjust the slider damper.
- Check to see if the stove needs a more complete cleaning.
- Turn the dial-a-fire up slightly (poor quality pellets will require slightly higher settings).
- Did the power go out?
- Contact your local Dealer for service.
√ If the stove goes out and there are no pellets in the liner, the auger is stopping.
- See “The auger motor will not function normally” and “The exhaust blower will not function
normally.”
