Troubleshooting
Observed Problem Possible Cause Remedy
C. The stove shuts down unex-
pectedly and the #3 error light is
ashing.
Control Panel Symptom:
The #3 light will be ashing if
the unit shuts down due to lack
of fuel or re.
1. The unit has run out of fuel. 1. Check fuel hopper and rell if low.
2. The auger is jammed or is
not feeding.
2. See “G. The unit is not feeding fuel, or is not feed-
ing correctly”
3. Unit failed to produce
enough heat during the startup
cycle.
3. If this is the rst re, or the rst re after the unit
has run out of fuel, the auger must be primed. Put a
handful of pellets into the burn pot before starting or
restart the unit after ve minutes to prime the auger.
If this fails see “ D. The unit fails to light.”
4. Too much primary air- the
feed rate is insufcient to keep
up with the burn rate.
4. If the unit shuts off and leaves completely un-
burned pellets in the burn pot it likely has too much
primary air. Push the slider damper in to reduce the
primary air ow to the unit. See “Setting the Slider
Damper” for more information.
5. Poor quality fuel. 5. Poor quality fuel may not produce enough heat to
maintain re in the unit on low heat levels. Increase
the heat level, increase the feed trim (See “Adjusting
Trim Settings,” or try a different fuel.
6. Exhaust Temperature Sensor
Failure.
6. Bypass the exhaust temperature sensor. If the unit
operates with the sensor bypassed, remove the sensor
and clean it with a dry cloth. If the unit still does not
operate with the sensor connected, replace the sensor.
D. The stove shuts down unex-
pectedly and the #4 error light is
ashing.
Control Panel Symptom:
The #4 light will be ashing if
the unit shuts down due to a high
limit condition.
1. The high limit sensor has
tripped.
1. Reset the high limit sensor. See “Resetting the
high Limit sensoR” Then perform the following
troubleshooting steps:
a. Turn the unit on and allow it to complete the
startup cycle. Check for air ow at the convection
air outlet. If airow is weak or not present, check for
buildup on the convection fan blades.
b. Was the room air fan control set to ‘off’? If yes,
bypass the 160ºF (71ºC sensor and restart the unit. If
the unit operates correctly, replace the 160ºF (71ºC)
sensor.
c. Is the convection (room air) fan working correctly?
If not, use a multi meter to ensure that the fan is get-
ting power. If it is, the fan may need to be replaced.
If not, the circuit board may need to be replaced.
d. If the problem still exists after completing the
above steps, the unit might be feeding too much fuel.
Check the auger motor to ensure that it is pulsing;
not operating continuously. Small fuel can cause the
unit to overfeed. If the auger is pulsing correctly,
trim the fuel feed down. See “Adjusting Trim Set-
tings.”
Troubleshooting
Observed Problem Possible Cause Remedy
E. The unit fails to light.
Control Panel Symptom:
The #3 light will be ashing if
the unit fails to light.
1. The burn pot liner is not
placed correctly.
1. The burn pot liner must be pushed tight against
the ignitor tube for proper operation. Check to make
sure that the liner is fully seated.
2. The ignitor is not operating. 2. Remove the burn pot liner and start the unit. Ob-
serve the end of the ignitor. It should begin to glow
bright orange after about 5 minutes. If not, check the
wiring to the ignitor. If the wiring is connected and
undamaged, use a multi meter to check if the ignitor
is getting power. If it is, the ignitor may need to be
replaced. If it is not, the circuit board may need to be
replaced.
3. The unit is not feeding. 3. If this is the rst re, or the rst re after the unit
has run out of fuel, the auger must be primed. Put a
handful of pellets into the burn pot before starting or
restart the unit after ve minutes to prime the auger.
If the unit does not seem to be feeding pellets see “G.
The unit is not feeding fuel, or is not feeding cor-
rectly.”
F. The unit will not shut off. 1. The unit is connected to a
thermostat and is running in
High/Low mode.
1. When operating in High/Low mode the unit will
not shut off. It will run on Low heat level setting
until the thermostat calls for heat.
Press the On/Off button to force the unit to shut
down.
Note: the unit will NOT restart automatically if
shut down manually.
2. The unit is connected to a
thermostat and is running in
Auto/Off mode.
2. When operating in Auto/Off mode the unit will run
on high until the thermostat is satised. When the
thermostat is satised, the unit will run on low until
either the thermostat calls for heat again, or 30 min-
utes passes. If the thermostat does not call for heat
within 30 minutes the unit will begin a shut down
cycle. The unit will restart when the thermostat calls
for heat again. The unit cannot be shut down manu-
ally when running in Auto/Off mode. Change the
operating mode to High/Low or Manual to shut the
unit down manually.
3. Exhaust temperature sensor
failure.
3. If the unit appears to be operating correctly (no
error codes ashing) but the unit has run out of fuel
and the re has gone out, the exhaust temperature
sensor may have failed. Disconnect one of the
brown wires from the sensor. If the unit begins ash-
ing a #3 error code, the exhaust temperature sensor
has failed. Replace the sensor.
