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 a fault code displayed. 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.
M AINTENANCE
ANNUAL 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 fol-
lowing 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.
• Drainage system. Check for blockage and/or leakage. Check hose connections at and internal to furnace.
• Wiring. Check electrical connections for tightness and/or corrosion. Check wires for damage.
• Filters.
FILTERS
FILTER MAINTENANCE
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.
DIAGNOSTIC CODES
1 flash, then pause System lockout
2 flashes, then pause Pressure switch stuck closed
3 flashes, then pause Pressure switch stuck open
4 flashes, then pause Open limit switch
5 flashes, then pause
Flame has been sensed when no flame
should be present (no call for heat)
6 flashes, then pause Open rollout switch
7 flashes, then pause Low flame sense signal
8 flashes, then pause Igniter relay fault
Continuous flashing 115 Volt AC power reversed
OFF Control failure
ON Normal operation
The LED will also flash once at power-up.
