follow the startup procedures found on pages 4 and 5 of
this booklet.
• If for some reason the vent is blocked, the draft safeguard
switch will shut off the furnace. Reset the switch by pushing
the button located on top of the switch. See page 2 or 3 for
switch location.
If the switch trips a second time, turn off the furnace and
call for service.
• Downflow/Horizontal Only—Check the manual reset
auxiliary limit switch located on the blower housing. If the
blower motor fails, this switch will shut off the furnace. Reset
it by pushing the button on the switch. If it trips again, turn
off the furnace and call for service.
• Check the manual reset flame rollout switch(es) located
near the burners. If the furnace has experienced a high-
temperature condition due to inadequate combustion air,
these switches will shut off the furnace. Reset the switch(es)
by pushing the button on the switch. If the switch trips a sec-
ond time, turn off the furnace and call for service.
• If your furnace still fails to operate, call your servicing
dealer for troubleshooting and repairs. Tell your dealer the
model and serial numbers for your furnace. (You should
have them recorded on page 8 of this booklet.) By knowing
exactly which furnace you have, the dealer may be able to
offer suggestions over the phone or save valuable time
through knowledgeable preparation for the service call.
• Your furnace control board has an LED fault code
light that indicates the furnace status. The LED will
flash short and long flashes. Look through the sight glass
on the furnace door and determine the code (number of
short and long flashes). Give the code and furnace model
number to your dealer when you call. By knowing exactly
which furnace you have and the LED code being displayed,
your dealer can save valuable time through knowledgeable
preparation for the service call.
Regular dealer maintenance
In addition to the type of routine maintenance you might be
willing to do, your furnace should be inspected regularly by
a properly trained service technician. A semiannual inspec-
tion (or annual inspection, at least) should include the fol-
lowing:
1. Inspection of all flue product passages including the
burners, heat exchanger, relief box, and vent pipe.
2. Inspection of all combustion and ventilation air pas-
sages and openings.
3. Close check of all gas pipes leading to and inside of
your furnace.
4. Inspection, cleaning, and lubrication (when required)
of the blower motor and wheel.
NOTE:
Refer to the unit Service Procedures for blower
motor oiling information. When required, the motor must
be oiled by a qualified service technician.
5. Routine inspection and cleaning/replacement of the air
filter.
6. Inspection of all supply- and return-air ducts for
obstructions, air leaks, and insulation. Any problems
found should be resolved at this time.
7. Inspect the return-air duct connection(s) at the furnace
to ensure it is physically sound, sealed to the furnace
casing, and terminates outside the space containing
the furnace.
8. Inspection of furnace installation for proper support
and any obvious deterioration of the furnace. The sup-
port must be sound and without sags, gaps, cracks,
etc., around the furnace base so as to provide an air seal
between the support and furnace.
9. A check for loose connections attaching individual
components. Inspection of all electrical wiring and
their connections.
10. Operational check of the furnace itself to determine
working condition. Repair or adjustment should be
made at this time.
Ask your servicing dealer for further details about an eco-
nomical service contract that covers seasonal inspections.
