Troubleshooting

If the stove goes out and there are no pellets in the liner, the auger is stopping.

General:

See “The auger motor will not function normally” and “The exhaust blower will not function normally.”

12.Light # 2 on Heat output bar flashing (Circuit Board Only). (The Vacuum Switch contacts have opened for more than 15 sec.)

Pinch, break or blockage in Vacuum Hose - Check hose for pinch points or damage, replace or re-route as required. Blow out Vacuum Hose

Blocked Hose Barb on Exhaust Channel - Use a paper clip to clean out Hose Barb or remove the Vacuum Hose from the Vacuum Switch and blow into the hose to remove blockage.

Blocked exhaust / venting system - Have stove and venting cleaned and inspected.

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.

Vacuum Switch failure - Bypass the vacuum switch, if this corrects the problem check for above problems before replacing the Vacuum Switch.

Damage to gray wires between Circuit Board and Vacuum Switch - Inspect wires and connectors

Combustion 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 82 V. with a line voltage >115V AC.

Check Vacuum levels in the exhaust channel by bypassing the vacuum switch, then remove the Vacuum hose from Vacuum Switch. Check exhaust vacuum readings by placing the open end of the Vacuum Hose on a Magnehelic Gauge. (readings must be above .10” W.C. on low fire).

If the motor fails to reach a 0.10” W.C. readings, then replace the Combustion Blower

To reset Circuit Board after a trouble code - push the ON/OFF button

FUSES:

F1 is the fuse to the inside of the circuit board controls. If F1 has blown there may have been an input power overload or a short in the convection fan.

F2 fuse closest fuse to the outside edge of the circuit board controls. If fuse F2 has blown then there was a electrical overload problem with one of the following parts: ignitor, auger motor, high limit switch, or exhaust blower.
