Troubleshooting Tips... Before you call for service
FAULT CODES - Press and hold MODE, then press AUX
This shows all current fault codes, and cycles through them. If there are no current faults, the display shows "--".
Pressing AUX clears the faults. Any other key exits and preserves the faults.
Fault Code Fault Meaning
Numbers
1 Inside fan fault. Fan motor not moving at commanded speed after 90 seconds of
drive. Fault clears after 10 minutes.
2 Outside fan fault. Fan motor not moving at command speed after 90 seconds of
drive. Fault clears after 10 minutes.
3 External thermostat wiring. Applied signal is not valid and has been constant for
30 seconds.
4 Inside thermistor fault. One of the inside thermistors is not reading valid
temperatures.
5 Outside thermistor fault.
One of the outside thermistors is not reading valid temperatures.
6 Compressor fault. No temperature change has been detected after 1 minute of
running.
7 Reverse valve fault. Temperature change not happening as expected after 1
minute of running.
8 Software fault.
9 Indoor coil freeze fault. The temperature of the inside coil has fallen below the
freeze threshold (34ºF).
10 Heat pump overload fault. The inside coil temperature is over the overload
threshold (131°F).
11 Overheat fault. The incoming air is too hot to run the heater.
12 UI board disconnected/failed.
13 Heater airflow fault. Indoor airflow is unexpectedly low. Fault clears after 10
minutes.
16 N/A
17 Outlet thermistor failure. Fault clears when thermistor reads value other than short
circuit or open circuit.
18 Outlet temperature overheat. The outgoing air is too hot. Fault clears when air
temperature drops below threshold.
19 Repeated outlet temperature overheat. The outgoing air is too hot. Check indoor
fan operation and check unit/ductwork for blockage.
23 Make-up Air Module Fault. Fan is not operating as expected
24 Make-up Air Module Vent Door Fault. Vent door validation failed
25 Abnormal Defrost Fault (heat pump models only). Will self clear after 4.5 days.
26 Air Conditioning Lockout Fault. Sets when outdoor ambient temperature drops
below 35ºF. Will self clear after Outdoor Ambient temperature rises above 40°F.
27 Inside Coil Vapor Temperature Sensor Fault (AZ9V only). Readings invalid. Fault
clears when readings are valid.
28 Outside Coil Vapor/Liquid Temperature Sensor Fault (AZ9V only). Readings
invalid. Fault clears when readings are valid.
29 Humidity Sensor Fault (AZ9V only). Readings invalid. Fault clears when readings
are valid.
30 EEV Superheat fault (AZ9V only). EEV unable to return superheat to valid range.
99 Inverter Fault (AZ9V only). Inverter board is in a faulted state that prevents it from
running normally.
