No Fuel - PSG CADDY ALTERNA II Installation And Operating Instructions Manual

10.3.2 NO FUEL

❖ The furnace ran out of pellets. Refill the hopper. Press on the
"ON/OFF" button
❖ The burn pot holes are blocked. Remove the burn pot and clean it thoroughly. Refer to the maintenance
section.
❖ The rotary valve, the auger is jammed or the gear motor failed. Go to the "TROUBLESHOOT
FURNACE" page on the LCD screen (see Section 10.2: Testing Components) and test the gear motors.
Make sure the hopper lid is closed. If one of the motors is not running, check if motor is defective or if the pot
auger or the rotary valve is jammed.
NOTE: IF THE HOPPER GEAR MOTOR FAILED OR THE HOPPER ROTARY VALVE IS JAMMED, TO
AVOID PELLET SPILLAGE, EMPTY THE HOPPER OF ITS CONTENTS BEFORE EXECUTING THE
FOLLOWING TESTS.
o
If a gear motor seems defective, check to make sure that electrical connections are not loose and check
the fuses E and F (see Section 11.9: Access the fuses) on the pellet control board. A defective fuse
will be darkened or will have a broken filament. If the fuses are good, the auger motor may be jammed
by an object.
If the hopper's rotary valve is jammed, empty the hopper's pellet contents completely to access the top
o
of the rotary valve. Once accessible, make sure that no object, other than wood pellets, are found in the
cavities of the rotary valve. Thereafter, before putting back wood pellets, close the hopper lid and go to
the "TROUBLESHOOT FURNACE" page of the LCD interface to test the auger motor 1. If the rotary
valve does not seem to be stuck and the gear motor working, contact your dealer or after-sale service to
run a complete test.
o
If the auger is jammed, remove it from its housing. First disconnect the motor (see Section 11.4: Auger
replacement part). Pull out the auger from the housing. Once the auger has been removed, make sure
the auger is straight, that the surface is not damaged and there are no burrs, or broken welds. Remove
any foreign material that may have caused the jam. Inspect the auger housing for signs of damage such
as burrs, rough spots, or grooves cut into the metal that could have caused a jam. Clean the auger
housing thoroughly to remove all pellet dust.
o
If no object appears to block the auger, reconnect the electrical connections of the motor and turn on the
furnace. BE CAREFUL NOT TO TAKE AN ELECTRIC SHOCK. Test the motor using the
"TROUBLESHOOT FURNACE" mode.
❖ The flue temperature sensor failed. The exhaust temperature probe (RTD) is a heat sensor located on the
exhaust housing. Its function is to tell the control board that the furnace has ignited properly by measuring
. Your furnace will only restart when the cool down cycle is completed.
