Fault Recall; Resetting From Lockout; Maintenance; Annual Inspection - Goodman GME8 Installation Instructions Manual

F R
AULT ECALL
The ignition control is equipped with a momentary pushbutton
switch that can be used to display on the diagnostic LED the last
five faults detected by the control. The control must be in Standby
Mode (no thermostat inputs) to use the feature. Depress the
pushbutton switch for approximately 2 seconds. Release the switch
when the LED is turned off. The diagnostic LED will then display
the flash codes associated with the last five detected faults. The
order of display is the most recent fault to the least recent fault.

ESETTING ROM OCKOUT
Furnace lockout results when a furnace is unable to achieve
ignition after three attempts. It is characterized by a non-functioning
furnace and a one flash diagnostic LED code from the red LED. 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 for 1 - 20 seconds.
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 Diagnostic
Chart for aid in determining the cause.

A
NNUAL INSPECTION
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.
• Heat exchanger. Check for corrosion and/or buildup within
the heat exchanger passageways.
• Burners. Check for proper ignition, burner flame, and flame
sense.
• Wiring. Check electrical connections for tightness and/or
corrosion. Check wires for damage.

• Filters.

A return air filter is not supplied with this furnace; however, there
must be a means of filtering all of the return air. The installer will

ILTER AINTENANCE
Improper filter maintenance is the most common cause of
inadequate heating or cooling performance. Filters should be
cleaned (permanent) or replaced (disposable) every two months
or as required. When replacing a filter, it must be replaced with a
filter of the same type and size.

Become familiar with filter location and procedures for removal,
cleaning and replacing them. If help is needed, contact the installer
of the furnace or a qualified servicer.

ILTER EMOVAL
Depending on the installation, differing filter arrangements can
be applied. Filters can be installed in either the central return
register or a side panel external filter rack (upflow only). A media
air filter or electronic air cleaner can be used as an alternate filter.
Follow the filter sizes given in the Recommended Minimum Filter
size table to ensure proper unit performance.
To remove filters from an external filter rack in an upright upflow
installation, follow the directions provided with external filter rack
kit. Internal filters are an accessory item and are not included
with your furnace. For further details, see your distributor.

To remove filters from an external filter rack in an upright upflow
installation, follow the directions provided with external filter rack
kit.
Clean, wash and dry a permanent filter. When using a permanent
filter, both sides should be sprayed with a dust adhesive as
recommended on adhesive container. Spray adhesives for use
with permanent filters can be found at some hardware stores. BE
SURE AIRFLOW DIRECTION ARROW POINTS TOWARDS THE
BLOWER.
Inspect filter. If your dirty filter is the disposable type, replace dirty
with the same type and size filter. If your dirty filter is a permanent
filter, clean as follows:
