Troubleshooting
• Exhaust Temperature Sensor failure. Bypass sensor located on Exhaust Blower, if stove now operates
properly, the unit may require cleaning or a new sensor. Contact your local dealer for service.
• Check the agitator to make sure it is turning properly
3. The exhaust motor will not function normally.
• Check the line fuse to see if it has blown.
• Open the access panels; check all connections against the wiring diagram.
• Check the Exhaust Blower voltage across the blower motor wires (>=115V on #5 setting and >= 75V
on #1 setting). – Replace the Circuit Board if the Voltage reading is less than 75 V. with a line voltage
of >115 V AC.
• Clean all exhaust passages and venting.
• Check and, if necessary, replace capacitor.
4. Light # 3 on Heat output bar flashing
(The Exhaust Temp. Switch contacts have opened.)
• Stove ran out of fuel - check fuel level in the hopper.
• See sections
#2 - Stove will not operate when hot, #3 - The Exhaust motor will not function normally,
and
#5 - Unit is on but auger does not turn at all for more suggestions.
• Severe negative pressure in area where unit is installed - Check the operation by opening a window,
does this solve the problem? If it does, install fresh air intake to unit or room. Venting system may
require vertical section to move termination into a low pressure zone.
• To reset Circuit Board after a trouble code - push the ON/OFF button.
5. Unit is on
but auger motor does not turn at all.
• Check the line fuse to see if it has blown.
• Check the Door and Ash Pan door - THEY MUST BE CLOSED TIGHT.
• If the Auger gear box does not turn but the motor’s armature does try to spin, then the auger is
jammed. Try to break apart jam by poking at the jam through the drop tube. If this fails then empty
the hopper and remove the Auger Cover **Remember to re-seal the cover after installation**
• Auger stopped running. Pinch, break or blockage in Vacuum Hose - Check hose for pinch points or
damage, replace or re-route as required. Blow out Vacuum Hose and intake pipe.
• Damage to wires between Circuit Board and Vacuum Switch and Auger Motor - Inspect wires and
connectors.
• Vacuum Switch failure - Bypass the vacuum switch, if this corrects the problem check for above
problems before replacing the Vacuum Switch.
• Blocked exhaust / venting system - Have stove and venting cleaned and inspected.
• Check Vacuum levels at the Vacuum Switch, with a Magnahelic Gauge (readings must be above .07”
W.C. on low fire).
6. Light # 4
on Heat output bar flashing
The 200 °F ( 93 °C) high limit temperature sensor
has tripped.
• Reset sensor and determine cause. Was it Convection Blower failure or Circuit board control
problems?
• Hopper lid has been left open for longer than two minutes.
