STOVE SHUTS OFF AND DISPLAYS WARNING CODE “E”
Possible Causes: Possible Remedies: (Unplug stove first when possible)
1. The hopper is empty. Refill the hopper.
2.
The burn pot holes are blocked.
Remove the burn pot and clean it thoroughly.
3.
The air damper is open too much for the low feed setting.
If the stove is on the low setting, you may need to close the damper all the way.
Slide the air supply control toward the minimum setting.
4.
The air inlet, interior chambers, or exhaust system is partly blocked.
Follow all cleaning procedures in the maintenance section of the owner’s
manual.
5.
The auger motor has failed.
Remove the auger motor from the auger shaft and try to run the motor separately by
pressing the fuel feed button on the control board. If the motor turns, the shaft is
jammed on something. If the motor does not turn, the motor is defective or there is a
faulty connection with the control board. To remove the auger motor, take the rear
panel off the stove body. Loosen the two screws holding the motor to the auger
shaft.
6.
The auger shaft is jammed.
Remove the auger shaft from the auger housing. Start by emptying the hopper. Take
the rear panel off the stove body. Then take the auger motor off by removing the
screws that hold the motor to the auger shaft. Once the motor is out, remove the four
screws on the steel plate that holds the auger shaft to the auger housing. Then rotate
the bottom end of the auger shaft down towards you until you can pull the shaft
down out of the stove. After you have removed the shaft, inspect it for bent flights,
burrs, or broken welds. Remove any foreign material that may have caused the jam.
Also, check the auger housing for signs of damage such as burrs, rough spots, or
grooves cut into the metal that could have caused a jam. Clean the auger housing
thoroughly to remove all pellet dust.
7.
The thermistor heat sensor has malfunctioned.
The thermistor is a heat sensor located on the exhaust housing. Its function
is to tell the control board that the unit has ignited properly by measuring the
heat in the exhaust. The pellet stove will not start feeding pellets at the
desired heat setting until it has received a signal from the thermistor heat
sensor. If the thermistor heat sensor is bad, the unit will stop after the
ignition cycle. If this situation occurs, call your dealer or technician.
