Troubleshooting
Caution: Installation of a new start-up timer without checking the ignitor resistance may cause
another failure to the new start-up timer due to a short in the ignitor. The proper resistance through
the ignitor should be 30Ω to 50Ω ± 3Ω.
2. The stove will not operate when hot.
General:
● Check the hopper for fuel.
● Incorrect air damper setting - Excessive air may consume the fire too quickly before the next drop of
fuel, leaving completely unburned fuel in the burn pot liner. Insufficient air will cause build up, further
restricting the air flow through the Burn Pot Liner. This in turn will cause the fuel to burn cold and very
slowly. Fuel may build up and smother the fire. (NOTE: Unit may require a change to the vent
system or installation of fresh air to correct Air to Fuel ratio problems).
● Combustion Blower failure - The Combustion Blower is not turning fast enough to generate the proper
vacuum in the fire box. Visual Check – is the blower motor turning?
● 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 0.10” W.C. on low fire).
Note: If the motor fails to reach a 0.10” W.C. reading, then replace the Combustion Blower.
● Poor Quality Fuel – Insufficient energy in the fuel to produce enough heat to keep the stove burning
or operational.
● Exhaust 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.
● The unit may require cleaning. Contact your local dealer for service.
● Unplug the stove, open the left side panel. Jump the two (2) brown leads that are attached to the
140°F (60°C) temperature sensor. If the stove operates replace the 140°F (60°C) sensor.
Circuit Board:
□ Check the Heat Level Indicator if a fire is not detected, or if the fire has gone out the #3 light will
flash because the Exhaust Temperature Sensor’s contacts have opened.
□ Check the Exhaust Blower voltage across the blower wires (>=114V on #5 setting and >= 52V on #1
setting). – Replace the Circuit Board if the Voltage reading is less than 82 V. with a line voltage >115
VAC.
□ Check the fuses on the circuit board (see “Troubleshooting - Fuses”).
3. The exhaust motor will not function normally.
General:
● Open the left side access panel; check all connections against the wiring diagram.
● If all the connections are verified and the exhaust blower does not function at all, tap lightly on the
exhaust blower’s motor end cap, this may loosen a tight motor.
● Apply 115 V AC directly to the exhaust blower. If the motor does not run, replace the blower.
● If the motor runs, have your dealer check the harness.
● See “2. The stove will not operate when hot.” section.
● Contact your local dealer for service.
4. The convection blower will not function normally.
General:
● Clean all grill openings at the back and below unit.
