How to Troubleshoot Mr Cool Mini Split Error Codes
When your Mr Cool mini split system displays an error code, it’s important to know how to troubleshoot and resolve the issue. Below, we provide some troubleshooting tips for common Mr Cool mini split error codes:
- E0: Check the indoor unit’s EEPROM parameters. If necessary, replace the parameters to resolve the error.
- E1: Verify the communication between the indoor and outdoor units. Address any issues with the communication to eliminate this error.
- E2: Inspect the zero-crossing signal detection circuit. Repair or replace the circuit as needed to fix this error.
- E3: Ensure that the indoor fan speed settings are within the control limits. Adjust the settings if necessary to resolve the error.
- E4: Test the indoor room temperature sensor (T1) for any open circuit or short circuit. If faulty, replace the sensor to fix this error.
- E5: Inspect the evaporator coil temperature sensor (T2) for any open circuit or short circuit. Replace the sensor if necessary to resolve the error.
- EC: Perform a refrigerant leakage detection test. If any leaks are detected, repair them to eliminate this error.
- F0: Check for overload current protection issues. Resolve any issues with the current protection to fix this error.
- F1: Test the outdoor ambient temperature sensor (T4) for any open circuit or short circuit. Replace the sensor if needed to resolve the error.
- F2: Inspect the condenser coil temperature sensor (T3) for any open circuit or short circuit. If faulty, replace the sensor to fix this error.
- F3: Verify the compressor discharge temperature sensor (TP) for any open circuit or short circuit. If necessary, replace the sensor to eliminate this error.
- F4: Check the outdoor unit’s EEPROM parameters. If required, replace the parameters to resolve this error.
- F5: Adjust the outdoor fan speed settings to ensure they are within control. This adjustment should help fix the error.
- P0: Address any IPM malfunction or IGBT over-strong current protection issues to eliminate this error.
- P1: Check for overvoltage or undervoltage conditions. Resolve these voltage issues to fix this error.
- P2: Inspect the high-temperature protection of the IPM module or compressor top. If necessary, repair this protection to eliminate the error.
- P3: Monitor the outdoor ambient temperature. Take necessary actions if the temperature is too low to resolve this error.
- P4: Resolve any inverter compressor drive errors to fix this error.
- P5: Troubleshoot conflicts between indoor units in a multi-zone setup. Resolving these conflicts should eliminate this error.
- P6: Identify and fix any low-pressure protection issues to resolve this error.
