F16: Left/Right Airflow Error
F90: PFC Protection
- A/D, voltage detected 4 times within 20 minutes (Outdoor unit overcurrent protection, excessive voltage >353.3V~385.8V)
- Possible Causes: 1. Reactor damaged, poor contact, or disconnected, resulting in high voltage. 2. Resistors between the three-phase coils of the compressor are unbalanced. 3. Outdoor P board check.
F91: Refrigerant System Error
- Current, tube temperature detected 2 times within 20 minutes (Difference between indoor tube temperature and air temperature is too small, indicating ineffective cooling/heating.)
- Possible Causes: 1. Refrigerant leak leading to insufficient refrigerant. 2. Three-way valve closed. 3. Compressor compression error. 4. Compressor stuck.
F93: Compressor Operation Error
- Compressor speed detected as abnormal 4 times within 20 minutes (Feedback signal error or loss)
- Possible Causes: 1. Outdoor P board malfunction. 2. Compressor malfunction. 3. Two-/Three-way valve not fully open.
F95: Cooling High-Pressure Protection
- Cooling mode: Outdoor tube temperature sensor detects temperature >62°C 4 times within 20 minutes.
- Possible Causes: 1. Outdoor condenser is excessively dirty. 2. Refrigerant is excessive. 3. Airflow circulation of outdoor unit is obstructed. Check areas: 1. Outdoor condenser; 2. Refrigerant pressure and operating current; 3. Outdoor unit installation location.
F96: IPM Overheating Protection
- When the temperature of the outdoor unit P board's variable frequency module is excessively high, detected 4 times within 30 minutes, the air conditioner stops working for protection.

制冷系统堵塞
制冷系统堵塞通常发生在毛细管和干燥过滤器处，堵塞原因包括：
脏堵：灰尘、杂质进入系统导致堵塞。
冰堵：制冷剂过量或系统泄漏导致制冷剂结冰堵塞。
焊堵：焊接过程中产生的焊渣进入系统堵塞。脏堵 毛细管进口处堵塞，常见原因是系统污物，如焊渣或锈蚀。敲击毛细管可暂时恢复通畅，也可根据管路凝露、结霜等现象判断堵塞位置。
冰堵 毛细管出口处堵塞，因系统含水，出口处汽化降温凝结形成冰粒。焊接处加热融化冰粒可恢复制冷，或关机后重新启动一段时间可制冷。
焊堵 毛细管焊接处堵塞，以新安装或维修过的空调较为常见。
制冷系统漏 制冷剂泄漏会导致制冷不良或失效，重点检查焊接头、铜管裂缝等处，目测即可发现油迹。
四通阀故障 制热时，四通阀吸合不良、串气或卡死。可检查通断电时的吸合状况，维修时反复通电或敲打阀门。
单向阀故障 制热时，制冷剂通过辅助毛细管，单向阀密封不严或辅助毛细管堵塞会影响制热。若制冷正常而制热差，需重点检查单向阀。
