8.3.1 P Code
STOVE SHUTS OFF AND APPEARS ON CONTROL BOARD
Possible Causes:
Possible Remedies: (Unplug stove first when
possible)
1. Pressure tap (located on the
exhaust blower) is blocked.
Pull off the air hose from the exhaust blower pressure
tap and from the negative (white) pressure switch tap.
WARNING: THE TUBE MUST ABSOLUTELY BE
DISCONNECTED FROM THE PRESSURE SWITCH
AS TO NOT DAMAGE IT.. Blow in the air tube. If air
flows freely, the hose is fine. If air does not flow
through the hose, use a thin wire to clear the blockage.
2. The flue is blocked or needs
cleaning.
One of the following components is obstructed or
blocked by ashes of by a foreign object; air intake
shutter, combustion blower, burn pot, heat exchangers
and exhaust channels, exhaust blower and or venting
system. Refer to the maintenance section.
3. The flue is not properly installed.
Make sure the venting system meets the criteria in the
installation section of this manual as well as the
venting system manufacturer’s instructions.
4. A back draft occurred inside the
flue.
This can occur on a very windy day or if your venting
system does not have a proper termination.
5. The pressure switch wire
connections are faulty.
Make sure that the pressure switch wires and
connections are not grounded or loose. Replace or
replug wires if necessary.
6. The pressure switch hose is
disconnected.
Make sure the pressure switch hose is well installed on
the exhaust blower pressure tap and on the white (-)
pressure switch tap. If not, reinstall it.
7. The exhaust or combustion
blower failed.
See Section 8.2: Testing a Component and test the
exhaust and the combustion blowers independently. If
one of them does not work, make sure there is power
and that blowers are well connected. If they still don’t
work, check fuse F4 and F5 on the control board. A
defective fuse will be darkened or will have a broken
filament. If the fuses are good, the combustion or
exhaust blower is probably defective. Replace the
faulty part.
