|---|---|---|---|
| Daikin | U4 | Transmission error between indoor & outdoor units | Check control wiring F1/F2 polarity and continuity |
| Daikin | E4 | Low pressure drop / actuation | Verify refrigerant charge and check for leaks using nitrogen |
| Daikin | L5 | Inverter compressor overcurrent | Check compressor windings and inverter PCB output |
| Mitsubishi | 6600 | Duplicate address error | Re-run auto-addressing sequence or manually set rotary switches |
| Mitsubishi | 4220 | Inverter bus voltage drop | Inspect main power supply phases and noise filters |
📋 Preventative Maintenance Checklist
- Log suction and discharge pressures across all operating modes.
- Check transmission voltage (16V DC) between indoor and outdoor terminals.
- Clean condenser coils to prevent high-pressure tripouts during peak summer.
- Verify oil return cycles are executing properly in the central controller.
