
Theaugermotordoesnotfunctionnormally.
 Iftheaugershaftdoesnotturnbutthemotorsarmaturetriestospinthenthisisasignyour augeris
jammed. Try toremovetheblockagebypokingatthefuelinthe  drop tube. If this doesnotwork
thenemptythehopperandremovetheaugercoverandcleartheblockage(Note:Beforeremoving
theaugercover,disconnectpowertotheunit).
 Makesurethehopperlipisfullyclosedtoengagethehopperlipinterlock.
 Checkforvoltageatthe augermotor. Ifnone,checkcircuitboard fuse.Replaceblown fusewith1
ampfuse.
 Ensuretheexhaustblowerisoperating.
 Checkthevacuumhoseforproperconnectionordamage.
 Bypassthevacuumswitchbyplacingajumperwireonthetwoelectricalconnections.Iftheauger
motorstartstofunctionnormally,
replacethevacuumswitch.
 Checkthemanualresetonthe200°Fhighlimitswitch.Ifthe switchhasbeentripped,checkforthe
causeoftheoverheating.Resettheswitchandcheckiftheaugeroperatesnormally.
 Bypass the 200° F high switch by placing a jumper
wire on the two electrical connections. If the
augermotorstartstofunctionnormally,replacethehighlimitswitch.
 Iftheaugerisnotjammedandyouhavetriedtheotherpossiblecauses,connect120voltsdirectly
totheaugermotor.Iftheaugermotordoesnotwork,replacetheaugermotor.

The200
o
FHigh‐limitswitchhastripped.
 Resettheswitch and determine thecause.It is normally afaultycirculation fan.Ifthecirculation
fan does not operate, apply 120 volts directly to the circulation  fan. If it still does not operate,
replacethecirculationfan.

Heaterwillnotshutoff.
 Ifroomthermostatisused,makesureitisturneddownbelowtheroomtemperature
 Disconnect one of the wires to the exhaust temperature sensor; the heater should then shut off.
Replacesensor
 DepresstheON/OFF buttonto"OFF".If theheaterwill stillnotshut off,
disconnectpowerto the
unitandcallyourlocaldealerforservice.

HeaterFlamekeepsgoingouton"LOW"setting.
Iftheflame goesout andleavesfreshunburned pelletsin theburn potliner, thenthe fireisgoing out
beforetheunitshutsoff.
 Onthecontrolpanel,
useHEATbuttontoturntheheatleveluptothenextsetting.Poorerquality
pelletsrequireaslightlyhighersetting.
 Ifitisonheatlevel1,youmayalsoadjustthefuelfeedingrateslightlybypressingtheAugerTrim
button.
