TROUBLE SHOOTING
See
fi
gure 26, page 33, for component locations.
The heater will not light.
•
Check that the heater is plugged in and that the wall outlet has power.
•
Unplug the unit then check all electrical connections against the Wiring Diagram in this manual.
•
Check the fuse on the circuit board.
•
If a thermostat is used, ensure it is calling for heat.
•
If your heater still does not light, contact your local dealer for service.
The heater will not operate when hot.
•
Check that the fuel hopper has enough pellets.
•
Check that the combustion air inlet is not blocked. Insuf
fi
cient air supply may cause the
fi
re to burn cold and may cause
fuel build up, in the pot, and smother the
fi
re.
•
Check that the exhaust fan is operating. If the fan is not operating properly, it may not generate enough vacuum in the
fi
rebox.
•
Check the 200°F high limit switch. This switch is manually reset. Check if it has tripped. If so, let cool and reset switch.
Check for cause of overheating. If switch trips again, contact your local dealer for service
•
Check the vacuum switch by shorting out the vacuum switch then depress ON/OFF button to “OFF” and back to “ON”.
If the unit starts to operate change the vacuum switch.
•
Check the exhaust temperature switch (located on the exhaust blower) by shorting out the exhaust temperature switch
then depress ON/OFF button to “OFF” and back to “ON”. If the unit starts to operate change the exhaust temperature
switch.
Exhaust blower does not operate normally.
•
Check all wiring connections.
•
Apply 120 volts directly to the exhaust blower. If the blower does not run replace the blower.
Circulation blower does not operate normally.
•
Check all wiring connections
•
Apply 120 volts directly to the circulation blower. If the blower does not run, replace the blower.
Igniter will not light fuel.
•
Check electrical connections (including fuse) to the igniter
•
Check that the igniter tube, which touches the burn pot, is not plugged with ash. If it is plugged remove the debris
(be sure to wait until everything has cooled to room temperature)
•
Check to see that burn pot is installed correctly (see page 29)
•
If igniter still does not work, replace it.
Note: The igniter should be glowing orange when in operation.
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 func-
tion 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 over-
heating. 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.
