The P5 error code in air conditioning systems can vary depending on the manufacturer and model. Below is a detailed summary of the possible causes and solutions for this error, along with recommendations for the major air conditioning manufacturers.
Summary of P5 Error Codes in Air Conditioners
| Brand | Code | Description | Solution |
|---|---|---|---|
| Panasonic | AC Power Supply | Problem with the power supply from the external electrical grid. | Check the voltage with a multimeter. If the issue persists, contact a technician. |
| Sharp | Phase Overcurrent | Excess current in one phase. | Check wiring and connections. |
| Trane | Phase Overcurrent | Excess current in one phase. | Check wiring and connections. |
| Trane | Condenser High-Temperature Protection | The condenser is overheating. | Check the condenser, clean it, and ensure proper airflow. |
| Gree | Drying | The compressor stops during the drying process. | Wait for the drying process to finish. |
| Gree | Heating Operation | The entire unit stops during heating operation. | Check the system and wait for the cycle to complete. |
| Daewoo | Low Outdoor Temperature | The outdoor temperature is too low for the air conditioner to function. | Adjust the temperature or turn off the unit. |
| Bosch | Indoor Unit Mode Conflict (Multi-zone Only) | The indoor units are set to different modes. | Adjust all indoor units to the same mode. |
| York | Indoor Unit Mode Conflict (Multi-zone Only) | The indoor units are set to different modes. | Adjust all indoor units to the same mode. |
| York | Compressor High-Temperature Protection | The compressor is overheating. | Check the compressor and airflow. |
| Midea | Inverter Module Protection | Problem with the inverter module. | Contact a qualified technician. |
| Midea | P5 – Protection against Current in Phase C | Excess current in Phase C. | Check the electrical supply, condenser heat exchange, and other system components. |
| Carrier | P5 (Indoor Unit) | Mode conflict. | Adjust all indoor units to the same mode. |
| Carrier | P5 (Outdoor Unit) | Protection against high temperatures in the condenser. | Clean the condenser and check airflow. |
Details about the P5 Code for Midea
The P5 code in Midea air conditioners is related to protection against current in Phase C, which occurs when the compressor’s current exceeds 25 A. Below are the steps to address this error:
- Check the power supply:
Ensure that there are no issues with the power supply and that the system is receiving proper voltage. - Check the condenser heat exchange:
Insufficient heat exchange can cause the error. Ensure that the condenser is clean and operating properly. - Check for obstructions on the high-pressure side:
Obstructions, such as a crushed tube or blocked expansion valve, can increase pressure and cause the P5 error. Inspect the pipes and system components. - Check for excess refrigerant:
If the system has too much refrigerant, it can overload the compressor. In this case, it is recommended to release some refrigerant and check the system. - Release some refrigerant:
If you observe oil loss during the discharge process, add the necessary amount of refrigerant. - Check the Inverter system:
If the inverter system is short-circuited or malfunctioning, it should be replaced. - Replace the compressor:
If the compressor has failed multiple times, it is advisable to replace it with a new one.
