4. TROUBLESHOOTING GUIDE
When your stove acts up, your first reaction may be to call for help.This guide may save time and money by
enabling you to solve simple problems yourself. Problems can be caused by only five factors: 1) poor fuel; 2)
poor operation or maintenance; 3) poor installation; 4) component failure; 5) factory defect. You can usually
solve the problems related to 1 and 2. Your dealer can solve problems relating to 3, 4 and 5. Refer to figures 24
- 27 to help locate indicated parts.
Should you need to contact your dealer or the manufacturer, please photocopy and fill out the form in
Appendix B. Try to answer as many questions as you can. Have it handy when you call. This will help
you obtain a much faster service.
STOVE SHUTS OFF AND APPEARS ON CONTROL BOARD
Possible Causes:
Possible Remedies: (Unplug stove first when possible)
1. Airflow pressure switch hose or pressure tap for hose are
blocked.
Unhook air hose from the airflow switch and blow through it. If air
flows freely, the hose and tube are fine. If air will not flow through
the hose, use a thin wire to clear the blockage.
2. The air inlet, burn pot, interior combustion air chambers,
combustion blower, or exhaust pipe are blocked with ash or
foreign material.
Follow all cleaning procedures in the maintenance section of the
owner‟s manual.
3. Vent pipe is incorrectly installed.
Check to make sure vent pipe installation meets the criteria in the
owner‟s manual as well as the pipe manufacturer‟s
recommendations.
4. The airflow pressure switch wire connections are faulty.
Check the connectors attached to the pressure switch.
5. The airflow pressure switch wires are pulled loose at the
connector on the wiring harness.
Check to see whether the wires are loose at the connectors.
6. Exhaust blower failure.
This blower must turn on when you start the unit. If it does not, make
sure there is power on the connections. If the power is connected,
the motor is probably defective; if there is no power, see #7.
7. Control board is not sending power to exhaust blower.
If there is no power going to the blower, check all connections. If all
wires are properly connected, you have a defective control board.
8. Control board not sending power to airflow pressure switch.
There should be a 120-volt current going to the air switch after the
stove has been on. You will need a technician to perform this test.
9. Airflow pressure switch has failed (very rare).
To test the airflow pressure switch, you need to disconnect the air
hose from the blower casing. With the other end still attached to the
switch, very gently suck on the loose end of the hose (you may want
to completely disconnect the hose from the stove and the switch first
and make sure it is clear). If you hear a click, the switch is working.
Be careful: too much suction can damage the switch.
