STOVE SHUTS OFF AND SHOWS WARNING CODE
"P"
Possible Causes:
1. Airflow pressure switch hose or hose connector tip are blocked.
2. The air inlet, burn pot, interior combustion air chambers, combustion
blower, or exhaust pipe are blocked with ash or foreign material.
3. Vent pipe is incorrectly installed.
4. The pressure switch connections are faulty.
5. The pressure switch wires are pulled loose from the connectors on
the wiring harness.
6. Combustion/exhaust blower failure.
7. Control board not sending power to combustion/exhaust blower.
8. Control board not sending power to pressure switch.
9. Airflow pressure switch has failed (very rare).
Possible Remedies: (Unplug stove first when possible)
Pull out 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. If the problem occurs again shortly after ,
you may have to remove accumulation on the pressure switch probe
located inside of exhaust blower housing(refer to maintenance section)
Follow all cleaning procedures in the maintenance section of the owner's
manual.
Check to make sure vent pipe installation meets criteria in owner's manual
and pipe manufacturer's recommendations.
Check the connectors that attach to the pressure switch.
Check to see if the wires are loose at the connector.
This blower must come on when you start the unit. If it does not, make
sure there is power on the connections, if so, the motor is likely to be
defective; if not refer to #7
If there is no power going to the combustion blower, check all connections.
If all wires are properly connected, you have a bad control board.
There should be 120-volt going through the pressure switch when the
stove is on. You will need a technician to perform this test.
To test the airflow pressure switch, you will 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 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.
