new ignition sequence. If flame is established then lost on
subsequent attempts, the control will recycle the ignition
sequence.
The diagnostic fault code is 1 flash for a lockout due
to failed ignition attempts. The integrated control will
automatically reset after one hour, or it can be reset
by removing the thermostat signal or disconnecting
the electrical power supply for over five seconds. If the
diagnostic red LED indicates an external lockout, perform
the following checks:
• Check the supply and manifold pressures
• Check the gas orifices for debris
• Check gas valve for proper operation
• Check flame sensor
A drop in flame signal can be caused by nearly
invisible coating on the sensor. Remove the sensor
and carefully clean with steel wool.
• Check wiring
• Check wiring for opens/shorts and miswiring.
IMPORTANT NOTE: If you have to frequently reset
your gas/electric package unit, it means that a
problem exists that should be corrected. Contact a
qualified servicer for further information.
Pressure Switch Stuck Open
A pressure switch stuck open can be caused by a
faulty pressure switch, faulty wiring, a disconnected or
damaged hose, a blocked or restricted flue, or a faulty
induced draft blower.
If the control senses an open pressure switch during
the pre-purge cycle, the induced draft blower only will
be energized. If the pressure switch opens after ignition
has begun the gas valve is de-energized, the circulator
blower heat off cycle begins, and the induced draft
blower remains on. The diagnostic LED (red) code is
two (2) flashes.
Pressure Switch Stuck Closed
A stuck closed pressure switch can be caused by a
faulty pressure switch or faulty wiring. If the control
encounters a pressure switch stuck closed, the induced
draft blower remains off. The diagnostic red LED code
for this fault is three (3) flashes.
Open Thermal Protection Device
If a limit switch opens, the gas valve is immediately de-
energized, the induced draft and air circulating blowers
are energized. The induced draft and air circulator
blowers remain energized until the limit switch re-closes.
The diagnostic LED (red) code for an open limit is four
(4) flashes.
Primary Limit
A primary limit will open due to excessive supply air
temperatures. This can be caused by a dirty filter,
excessive duct static, insufficient air flow, or a faulty
limit. Check filters, total external duct static, blower
motor, blower motor speed tap (see wiring diagram),
and limit. This limit will automatically reset once the
temperature falls below a preset level.
Auxiliary/Secondary Limit
A dirty filter, excessive duct static, insufficient air flow, a
faulty limit, or a failed circulator blower can cause this
limit to open. Check filters, total external duct static,
circulator blower motor, blower motor speed tap (see
wiring diagram), and limit. An interruption in electrical
power during a heating cycle may also cause the
auxiliary limit to open. The automatic reset secondary
limit is located on top of the circulator blower assembly.
Rollout Limit
If the burner flames are not properly drawn into the heat
exchanger, the flame rollout protection device will open.
Possible causes are restricted or blocked flue passages,
blocked or cracked heat exchanger, a failed induced
draft blower, or insufficient combustion air. The rollout
protection device is a manual reset limit located on the
burner bracket. The cause of the flame rollout must be
determined and corrected before resetting the limit.
Flame Detected with Gas Valve Closed
If flame is detected with the gas valve de-energized, the
combustion and air circulator blowers are energized.
The diagnostic fault code is five (5) flashes (red LED)
for this condition. The flame diagnostic LED (amber) will
flash (2) times to indicate this condition. The control can
be reset by removing the power supply to the unit or it
will automatically reset after one hour. Miswiring is the
probable cause for this fault.
Low Flame Signal
Under some conditions, the fuel or air supply can create a
nearly invisible coating on the flame sensor. This coating
acts as an insulator causing a drop in the flame signal.
If the flame signal drops below a predetermined value,
the ignition control will display an error code of (1) flash
on the amber diagnostic LED. The unit will continue to
operate until the control can no longer detect flame.
Abnormal Operation - Cooling
Short Cycle Compressor Delay
The automatic ignition control has a built-in feature that
prevents damage to the compressor in short cycling
situations. In the event of intermittent power losses or
intermittent thermostat operation, the ignition control
will delay output to the compressor contactor for three
minutes from the time power is restored or thermostat
call for cooling is restored. (Compressor is off a total
of three minutes). The diagnostic red LED will flash six
(6) times to indicate the compressor contactor output is
being delayed.
NOTE: Some electronic thermostats also have a built-
in compressor short cycle timer that may be longer
than the three minute delay given above. If you are
using an electronic thermostat and the compressor has
