they are open and unobstructed. If this isn’t the cause of the
problem, call your servicing dealer.
If your furnace isn’t operating at all, check the following list
for easily solved problems:
• Is your thermostat set above room temperature? Is the
HEAT mode selected?
• Is the electrical power supply switch on? Is the blower
access door firmly in place? Are any fuses blown? (There is a
fuse on the furnace control.) Has a circuit breaker tripped?
• Is the manual shut-off valve in the gas supply pipe leading
to the furnace open? Does the lever point in the same direction
that the pipe runs (open)? Or is it at a right angle to the pipe
(closed)?
NOTE:
Before proceeding with the next checks, turn off the
electrical power supply to the furnace. Remove access door.
• Is the switch on the gas valve turned to the ON position? If
this or the preceding check shows an interruption in the gas
supply, make sure the gas has not been shut off for safety rea-
sons. If nothing else seems to be wrong, follow the startup pro-
cedures found on pages 4 and 5 of this booklet.
• If for some reason the vent is blocked, the blocked vent safe-
guard switch will shut off the furnace. (See page 2 or 3 for
switch location.) The switch will automatically reset after the
furnace cools off.
• Check the manual reset limit switches located on the end of
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 switches by pushing the button
on the switch. If the switch trips a second time, turn off the
furnace and call for service.
• If your furnace still fails to operate, call your servicing deal-
er 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.
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 inspection
(or annual inspection, at least) should include the following:
1. Inspection of all flue gas passages including the burners,
heat exchanger, inducer, elbow, and vent pipe.
2. Inspection of all combustion and ventilation air
passages and openings.
3. Close check of all gas pipes leading to and inside of your
furnace.
4. Inspection and cleaning of the blower motor and wheel.
5. Routine inspection and cleaning/replacement of the air filter.
6. Inspection of all supply- and return-air ducts for obstruc-
tions, air leaks, and insulation. Any problems found should
be resolved at this time.
7. Inspection of furnace installation for proper support and any
obvious deterioration of the furnace. The support must be
sound and without sags, gaps, cracks, etc., around the fur-
nace base so as to provide an air seal between the return-air
duct and furnace.
8. A check for loose connections attaching individual compo-
nents. Inspection of all electrical wiring and their connections.
9. 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 econom-
ical service contract that covers seasonal inspections.
