Table 17: Alarm and Diagnostic List
Alarm Designation Origin Description Status/Troubleshooting Information
No Active Alarm
Locked Rotor Circuit 1 CA1
Comfort Alert Code 4. Circuit 1 shutdown
and retry after Anti-Short Cycle Delay (ASCD).
Maximum is 3 attempts.
• Low line voltage
• Excessive Refrigerant in compressor
• Seized bearings in compressor
Open Circuit 1 CA1
Comfort Alert Code 5. Circuit 1 shutdown and
retry after ASCD. Note: This alarm is sent by the
Comfort Alert Module only after the fault has been
sensed for a minimum of 4 hours.
• Condensing unit power disconnect
is open
• Compressor circuit breaker or fuses
are open
• Compressor contactor has failed open
• High pressure switch is open and
requires manual reset
• Broken supply wires or connector is
not making contact
• Unusually long compressor protector
reset time due to extreme ambient
temperature
• Compressor windings are damaged
Missing Phase Circuit 1 CA1 Comfort Alert Code 6. Circuit 1 shutdown.
• Compressor fuse is open on one
phase
• Broken wire or connector on one
phase
• Compressor motor winding is
damaged
• Utility supply has dropped one phase
Reverse Phase Circuit 1 CA1 Comfort Alert Code 7. Circuit 1 shutdown.
• Compressor running backward due to
supply phase reversal
Welded Contactor Circuit 1 CA1
Comfort Alert Code 8. Run outdoor and indoor
fans continuously for circuit 2 and change mode
of operation to Unoccupied Auto. This procedure
prevents the Space Temperature from reaching
extreme values.
• Compressor contactor has failed
closed
• Thermostat demand signal not
connected to module
Low Voltage Circuit 1 CA1
Comfort Alert Code 9. Shutdown and wait for
voltage to return to operational levels.
• Control circuit transformer is
overloaded
• Low line voltage to compressor
Low Voltage DDC Controller De-energize all relay outputs.
Failed Ignition IFC IFC locks out for 1 hour
• Gas Valve Not Turned On
• Little or No Supply Gas
• Incorrect Manifold Pressure
• No Ignition Source, Direct Spark
Ignition (DSI)
• No 24 Volt Power to Gas Valve •Bad
Gas Valve
Low Flame Sense IFC
IFC flashes error code on LED, transmits the
warning through the network, but otherwise
operates normally
• Dirty Flame Sensor
• Unit Not Properly Grounded
• Incorrect Polarity
• Flame Sensor Incorrectly Wired
• Bad Flame Sensor
Flame Lost IFC
If lost 17 times within single call for heat, locks out
for 1 hour. Otherwise retry ignition.
Unexpected Flame IFC
IFC Energizes inducer and main blower. Locks out
for 1 hour
AC Low Pressure Switch 1 Trip-LP1 DDC Controller
If the low pressure switch trips 3 times within
120 minutes of operation during the same call
for heating operation, the control will lock out
compressor and outdoor fan operation. If the
lock-out due to low pressure occurs at an outdoor
ambient temperature below 5 °F, the control will
automatically exit the lock-out mode when the
outdoor ambient temperature rises above 5 °F. LPS
is ignored during defrost.
• Unit has low refrigerant charge
• Indoor coil frozen (cooling mode)
• Dirty indoor coil or filter (cooling
mode)
• Outdoor coil is frozen (heating mode)
• Expansion valve in not operating
correctly
