Open manufacturer sourceManufacturer meanings by device / model family
A code may mean different things on different products. Check the device type and manual scope for each entry.
- ATXC-B (six exact models): Inverter IPM / IGBT fault — Manufacturer source
- ATXB-C (two exact models): Output overcurrent — Manufacturer source
- Daikin Türkiye genel destek listesi: General support text describes compressor lock; not proof of a specific part failure — Manufacturer source
Do not open electrical components, gas or refrigerant circuits; consult qualified service.
What does this code mean?
Compressor cannot start. The exact model manual determines applicability; a fault code alone does not prove a particular component is defective.
Source scope: Compatibility with specific model numbers has not been established. Always check your exact appliance manual.
The manufacturer lists this code and general meaning; compatibility with your exact model has not been verified. Follow your model manual.
Open manufacturer sourceATXC-B identifies L5 as an inverter IPM/IGBT error; Daikin Turkey also discusses compressor lock. Confirm the exact series before diagnosis.

- 01
Record the exact code and when it appeared
Note every letter and digit, the stage of the cycle and the full model label. Error meanings can vary between models.
What the result means: This prevents applying guidance for a different model or a similar-looking code.
- 02
Check accessible air filters and vents
With the unit off, clean only user-removable filters and clear obvious obstructions. Do not open the outdoor electrical cabinet.
What the result means: Blocked airflow can affect operation but may not explain the entire code.
- 03
Request service for repeated faults
Stop the unit if it makes abnormal sounds, trips the breaker or cannot heat/cool. Refrigerant handling and electrical testing require a technician.
What the result means: Provide both indoor and outdoor model numbers; never top up refrigerant blindly.
- 04
Prepare precise notes for the technician
Provide the code, model number, stage of the program, sounds and any leak. Avoid opening a warranty-covered appliance or authorizing replacements without diagnosis.
What the result means: A technician can test components rather than guessing from the code.
Stop immediately for leaks, smoke, burning smell or electrical danger. For gas leaks, leave the area and call local emergency services.
How do you actually fix this?
Start with safe checks. Some codes have no safe home fix; in that case we explain what the professional repair actually involves.
Practical fixes you can try
- Stop the unit, check operating mode and set temperature, and clean an accessible indoor filter as instructed.
- If the warning repeats, stop retries. Do not touch outdoor service valves, copper lines or refrigerant charging points.
- Low refrigerant is not proved by a code or weak cooling alone; simply topping up without investigating leaks is not a reliable repair.
If it persists, how is it actually repaired?
A qualified HVAC technician checks temperatures, pressures and sensors, locates and properly repairs any leak, tests the sealed circuit and services charge to manufacturer specification. Compressor and electronics faults are diagnosed separately.
How do you know it is fixed? Cooling/heating and measured operating conditions must return to the model specification without protection faults.
Safety and warranty: Warranty terms depend on manufacturer, model and local law. Damage caused by unauthorised disassembly or improper repair may be excluded. Live electrical work, gas, refrigerant circuits and sealed cabinets require qualified professionals; this is not a DIY instruction for those tasks.
Evidence: The manufacturer link above supports the broad code meaning. The repair pathway is a general technical diagnostic explanation, not a confirmed failed-part diagnosis for every model.
