Diagnostic Chart
High voltage!
To avoid personal injury or death due to
electrical shock, disconnect electrical
power BEFORE performing any service or

maintenance.

Refer to the Troubleshooting Chart in the back of this
manual for assistance in determining the source of unit
operational problems. The 7-segment LED displays will
display an error code that may contain a letter and number.
The error code may be used to assist in troubleshooting
the unit.
Resetting From Lockout
Furnace lockout results when a furnace is unable to
achieve ignition after three attempts during a single call for
heat. It is characterized by a non-functioning furnace and
an EE0 code displayed on the 7-segment display. If the
furnace is in "lockout", it will (or can be) reset in any of the
following ways.
1. Automatic reset. The integrated control module will
automatically reset itself and attempt to resume
normal operations following a one hour lockout period.
2. Manual power interruption. Interrupt 115 volt power to
the furnace.
3. Manual thermostat cycle. Lower the thermostat
so that there is no longer a call for heat for 1 - 20
seconds then reset to previous setting.
NOTE: If the condition which originally caused the
lockout still exists, the control will return to
lockout. Refer to the Troubleshooting Chart for
aid in determining the cause.
MAINTENANCE
Annual Inspection
To avoid electrical shock, injury or death,
disconnect electrical power before
performing any maintenance. If you must
handle the igniter, handle with care. Touching
the igniter element with bare fingers, rough
handling or vibration could damage the
igniter resulting in premature failure. Only
a qualified servicer should ever handle the
igniter.
WARNING
WARNING
The furnace should be inspected by a qualified installer, or
service agency at least once per year. This check should
be performed at the beginning of the heating season.
This will ensure that all furnace components are in proper
working order and that the heating system functions
appropriately. Pay particular attention to the following items
Repair or service as necessary.
• Flue pipe system. Check for blockage and/or leakage.
Check the outside termination and the connections at
and internal to the furnace.
• Wiring. Check electrical connections for tightness and/
or corrosion. Check wires for damage.
Filter Maintenance
Improper filter maintenance is the most common cause
of inadequate heating or cooling performance. Filters
should be cleaned (permanent) or replaced (disposable) as
required.
Burners
Visually inspect the burner flames periodically during the
heating season. Turn on the furnace at the thermostat and
allow several minutes for flames to stabilize, since any
dislodged dust will alter the flames normal appearance.
Flames should be stable, quiet, soft, and blue (dust may
cause orange tips but they must not be yellow). They
should extend directly outward from the burners without
curling, floating, or lifting off. Flames must not impinge on
the sides of the heat exchanger firing tubes.
Induced Draft and Circulator Blowers
To ensure proper unit performance, adhere to the filter
sizes given in the recommended minimum filter size table or
specification sheet applicable to your model.
The bearings in the induced draft blower and circulator
blower motors are permanently lubricated by the
manufacturer. No further lubrication is required. Check
motor windings for accumulation of dust which may cause
overheating. Clean as necessary.
Condensate Trap and Drain System
(Qualified Servicer Only)
Annually inspect the drain tubes, drain trap, and field-
supplied drain line for proper condensate drainage. Check
drain system for hose connection tightness, blockage, and
leaks. Clean or repair as necessary.
