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.
