When your stove acts out of the ordinary, the first reaction is to call for help. This guide may save time and money by enabling you to solve
simple problems yourself. Problems can be caused by to only five factors: 1) poor fuel; 2) poor operation or maintenance; 3) poor
installation; 4) component failure; 5) factory defect. You can usually solve those problems related to 1 and 2. Your dealer can solve
problems relating to 3, 4 and 5. Refer to figures 26 - 29 to help locate indicated parts.
STOVE SHUTS OFF AND APPEARS ON CONTROL BOARD
Possible Causes: Possible Remedies: (Unplug stove first when possible)
1. Airflow pressure switch hose or pressure tab 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 throw 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 criteria in owner’s
manual and pipe manufacturer.
4. The airflow pressure switch wire connections are faulty.
Check the connectors that attach to the airflow pressure switch.
5. The airflow pressure switch wires are pulled loose at the
connector on the wiring harness.
Check to see if the wires are loose at the connector.
6. Combustion/exhaust blower failure.
With the stove on, check to see if the combustion/exhaust blower is
running. If it is not, you will need to check for power going to the
combustion/exhaust blower. Current reading may vary. If there is
power, the blower is bad. If there is not, see #7.
7. Control board not sending power to combustion/exhaust
blower.
If there is no current going to the combustion blower, check all wire
connections. If all wires are properly connected, you have a bad
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 will need to disconnect the
air hose from the body of the stove. With the other end still attached
to the switch, very gently suck on the loose end of the hose (you
may want to remove the hose entirely off 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 VACUUM CAN DAMAGE THE
SWITCH.
