IQ-XA-R32 Inverter

Eco Energy Saving Technology:

Powered by an advanced inverter compressor (featuring premium SANYO or GMCC components) for optimized power consumption.

Smart Wi-Fi Control:

Easily manage your indoor climate and temperature ranges via remote or Wi-Fi connectivity.

Faster Cooling & Heating:

High-volume air circulation (1500/1550m³ ) ensures your space reaches the perfect temperature rapidly.

All-Weather Resilience:

Operates efficiently across wide ambient temperature spans, delivering robust performance even in extreme conditions.

Air Conditioner Service Manual — Failure Codes

Refer to the diagnostic trouble codes below for system maintenance and troubleshooting parameters:

Code Reason / Description Remark / Troubleshooting Focus
E0 IDU & ODU Communication failure Check if IDU & ODU wiring connection is correct. Check PCB.
E1 IDU Room Temperature sensor failure (IDU RT failure) Check IDU sensor and PCB.
E2 IDU Coil temperature sensor failure (IDU IPT failure) Check IDU sensor and PCB.
E3 ODU Coil temperature sensor failure (OPT) Check ODU coil sensor and ODU PCB.
E4 AC Cooling system abnormal Gas leakage? Check if 2-way or 3-way valve is blocked, etc.
E5 IDU/ODU mismatched failure Special performance test constraint on production line.
E6 IDU PG Fan motor / DC fan motor works abnormal (IDU failure) Check fan motor, fan blade, and PCB.
E7 ODU Ambient Temperature sensor failure Check ODU ambient sensor and ODU PCB.
E8 ODU Discharge Temperature sensor failure Check ODU discharge sensor and ODU PCB.
E9 IPM / Compressor driving control abnormal Check ODU PCB, compressor, etc. Triggers after 6 continuous P0 stops.
EA ODU Current Test circuit failure ODU PCB broken?
Eb Communication abnormal of Main PCB and Display board Check display board and main PCB.
EE ODU EEPROM failure 1. ODU PCB broken?
2. Try to power-cycle/re-power AC unit.
EF ODU DC fan motor failure Check fan motor, ODU PCB.
EU ODU Voltage test circuit abnormal ODU PCB error. Activated if tested effective value is < 50V for 3s.
P0 IPM module protection IPM overheat or overcurrent. Check U/V/W wiring, AC pressure, or ODU fan.
P1 Over / under voltage protection Power supply abnormal (V > 260V or V < 150V) or ODU PCB busbar fault.
P2 Over current protection Running current exceeds Imax. Clean IDU filter/ODU condenser or replace PCB.
P4 ODU Discharge pipe Over temperature protection Discharge temp > 60°C. Check ventilation, dirty condenser, or gas levels.
P5 Sub-cooling protection on Cooling mode Evaporator coil IPT < 1°C for 3 min. Check filters, blockages, or fan motor.
P6 Overheating protection on Cooling mode Condenser coil OPT ≥ 62°C. Check ODU fan motor, sensor connection, or PCB.
P7 Overheating protection on Heating mode Evaporator coil IPT ≥ 62°C. Check IDU fan motor, sensor, or PCB.
P8 Outdoor Over/Under temperature protection Ambient temp out of spec range (Cooling: < -20°C / > 63°C; Heating: ≥ 40°C).
P9 Compressor driving protection (Load abnormal) Please check troubleshooting flowchart documentation for details.
PA Communication failure for TOP flow unit/ Preset mode conflict IDU Failure. Review specific preset profiles.
F0 Infrared Customer feeling test sensor failure (IDU failure) Querying via remote controller interface.
F1 Electric Power test module failure (IDU failure) Querying via remote controller interface.
F2 Discharge temperature sensor failure PROTECTION Please check troubleshooting documentation for details.
F3 ODU coil temperature failure PROTECTION Please check troubleshooting documentation for details.
F4 Cooling system gas flow abnormal PROTECTION 2-way or 3-way valve closed on installation? Check IPT sensor.
F5 PFC PROTECTION Please check troubleshooting documentation for details.
F6 Compressor lack of phase / Anti-phase PROTECTION Check compressor wiring connector. Replace ODU PCB or compressor if faulty.
F7 IPM Module temperature PROTECTION IPM temp > 95°C. Verify heat sink contact/screws, clean debris, check valves.
F8 4-Way Valve reversing abnormal Heating mode failure (IPT cold). Test valve coil resistance & 220V on valve.
F9 The module temperature test circuit failure ODU PCB malfunction.
FA The compressor Phase-current test circuit failure ODU PCB malfunction.
Fb ~ Fn Limiting/Reducing frequency protection modes Frequency limiting due to overload, high consumption, current, temp, etc. (Remote Query)
Fy Gas leakage protection No variations on coil temps while discharge is high. Repair leaks & recharge gas.
bf / bc / bj TVOC / PM2.5 / Humidity sensor failure (IDU faults) Optional features. Requires remote controller check process.
💡 Remote Controller Failure Query Function

As indicated in the manual instructions, specialized sub-codes (Fb to bj) require manual remote verification. While the indoor unit is operating, press the ECO button 8 times within 8 seconds. The internal buzzer will emit a "BI-BI" tone twice, allowing you to cycle through and inspect active special frequency limits or sensor faults.
