Why does my Thermal Zone A/C 9A45YIMI show error P1?
If your Thermal Zone Heat Pump displays error code P1, it indicates over voltage or over low voltage protection. First, check the supply voltage. If the voltage is within the correct range and the problem persists, the outdoor PCB may need to be replaced.
What to do if my Thermal Zone Heat Pump displays error code EC?
If your Thermal Zone Heat Pump is showing error code EC, it means there is a refrigerant leakage detection. You should find the leak and repair it. Alternatively, the indoor PCB might need replacement.
How to fix E1 error on Thermal Zone A/C 9A45YIMI Heat Pump?
If your Thermal Zone Heat Pump displays error code E1, this indicates an indoor to outdoor units communication error. Check the wiring for any cross wiring and ensure wire continuity. If the wiring is correct, the PC board might need to be replaced.
What does error E4 mean on a Thermal Zone Heat Pump?
If your Thermal Zone Heat Pump displays error code E4, it means the indoor room temperature sensor T1 has an open or short circuit. You may need to replace the indoor room temperature sensor, and if that doesn't work, consider replacing the indoor PCB.
How to troubleshoot E5 error on Thermal Zone A/C 9A45YIMI Heat Pump?
If your Thermal Zone Heat Pump displays error code E5, it indicates that the evaporator coil temperature sensor T2 has an open circuit or short circuit. You may need to replace the evaporator coil temperature sensor, or the indoor PCB.
What causes F2 error in Thermal Zone A/C 9A45YIMI?
If your Thermal Zone Heat Pump shows error code F2, it indicates that the condenser coil temperature sensor T3 has an open circuit or short circuit. Try replacing the condenser coil temperature sensor. If the problem continues, replace the indoor PCB.
How do I fix F1 error on my Thermal Zone A/C 9A45YIMI Heat Pump?
If your Thermal Zone Heat Pump is showing error code F1, it indicates that the outdoor temperature sensor T4 has an open circuit or short circuit. Replace the outdoor temperature sensor. If the issue persists, you might need to replace the indoor PCB.
What to do if Thermal Zone A/C 9A45YIMI Heat Pump shows E3 error?
If your Thermal Zone Heat Pump displays error code E3, it means the indoor fan speed has been out of control. Replace the indoor PCB and/or the indoor fan motor.
What does P4 error mean on Thermal Zone Heat Pump?
If your Thermal Zone Heat Pump displays error code P4, it indicates an inverter compressor drive error. Check the IPM module and the compressor resistance (0.7ohm), coil to coil and to gnd.
How to resolve F3 error on Thermal Zone Heat Pump?
If your Thermal Zone Heat Pump displays error code F3, it means the compressor discharge temperature sensor T5 has an open circuit or short circuit. Replace the compressor discharge temperature sensor. If the problem continues, replace the indoor PCB.
