Troubleshooting
üCheck the exhaust blower voltage across the blower wires (>=114V on #5 setting and >= 82V on #1
setting). – Replace the Circuit Board if the Voltage reading is less than 82V. with a line voltage >115V
AC.
üCheck vacuum levels in the exhaust channel by bypassing the vacuum switch, then remove the vacuum
hose from vacuum switch. Check the vacuum readings by placing the open end of the vacuum hose on
a Magnahelic Gauge (readings must be above 0.07” W.C. (17.4 Pa) on low fire).
üPoor quality fuel – insufficient energy in the fuel to produce enough heat to keep the stove burning or
operational.
üExhaust 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.
üContact your local dealer for service.
3. The exhaust motor will not function normally.
üOpen the left side access panel; check all connections against the wiring diagram.
üSee “2. The stove will not operate when hot.” Section.
4. Light # 2 on Heat output bar flashing
(The 200 °F ( 93 °C) high limit temperature sensor has tripped.)
üReset sensor and determine cause – was it a convection blower failure? Test by connecting it directly
to power.
To reset Circuit Board after a trouble code - push the ON/OFF button
5. The auger motor will not function normally.
üThe burn pot liner may require cleaning. Build up in the burn pot will cause the unit to shut off.
üCheck for obstructions in the hopper system.
üEnsure door is closed and ash pan is closed. The auger motor will stop if there is not enough vacuum
in the stove.
üPinch, break or blockage in vacuum hose - check hose for pinch points or damage, replace or re-route
as required. Blow out vacuum hose
üBlocked exhaust / venting system - have stove and venting cleaned and inspected.
üSevere 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.
üVacuum switch failure - bypass the vacuum switch, if this corrects the problem check for above problems
before replacing the vacuum switch.
üDamage to orange wires between circuit board and vacuum switch - inspect wires and connectors
üCombustion blower failure - the combustion blower is not turning fast enough to generate the proper
vacuum in the exhaust channel. Visual check; is the blower motor turning? Check the exhaust blower
voltage across the blower wires (>=114V on #5 setting and >= 82V on #1 setting). – Replace the
circuit board if the Voltage reading is less than 82V. with a line voltage >114V AC.
üCheck vacuum levels by bypassing the vacuum switch, then remove the Vacuum hose from Vacuum
Switch. Check vacuum readings by placing the open end of the Vacuum Hose on a Magnahelic Gauge.
(readings must be above .07” W.C. on low fire).
üCall your local dealer for service.
