SYMPTOM TEST SOLUTION
The 200°F (93°)
high limit tempera-
ture sensor has
tripped
The heater will not
turn off
The heater keeps
going out
Excessive carbon
build up in the
firebox, low heat
out put
Unit is burning dirty
and lazy
- Reset the sensor and determine whether it was the convection blower or 160°F (71°C) temperature
sensor failure. Bypass the 160°F (71°C) sensor. Does the convection blower not come on high? If no
than replace the blower.
- Disconnect one of the brown wires from the exhaust temperature sensor and if the unit continues to
operate, contact your local dealer for service.
- Compare the wiring diagram to the start control module and the connections to the 140°F (60°C)
temperature sensor. Check the connections.
- Remove one of the brown wires from the 140°F (60°C) temperature sensor. The heater should be shut
down right away as long as the start button was not pressed within 15 minutes of this test. If the heater
shuts down within 15 minutes, replace the 140°F (60°C) sensor. If the heater does not shut down in 15
minutes, test the switch.
- The heater must be cold to test the switch. Pull the plug, then plug the heater back in. If the heater fails
to start, replace the switch.
- Due to different installation set ups, length and size of venting and fuel quality, the low feed setting from
the factory will not always be correct. It may be necessary to experiment with feed rate vs air control.
(For example, #2 may be your lowest setting).
- If the heater goes out and leaves fresh unburned pellets or cigarette-like ashes in the burn pot, the fire
is going out before the heater shuts off.
- Check to see if the air control rod is in the correct position.
- Turn the feed rate up slightly (poor quality pellets will require slightly higher settings).
- Check to see if the heater needs a more complete cleaning as well as the burn pot, venting, etc...
- Was there a power failure?
- Contact your local dealer for service
- If the heater goes out and there are no pellets in the burn pot, the auger may be slipping .
- See "The auger motor will not function normally" and "The exhaust blower will not function normally".
- Check quality of pellets. Even pellets from the same manufacturer can vary in quality since the materials
they use to form pellets may also vary.
- Moisture content of pellets too high. Pellets must be stored in a dry place. Areas such as a garage are
too damp causing pellets to absorb moisture.
- Check that all exhaust and intake pathways are clear of any obstructions.
- Burn pot is clean.
- Pellets are dry.
- Venting and terminal are clear of obstructions.
- Exhaust blower is operation and is clean.
