What Does Error P2 Mean?

The Daewoo air conditioner P2 error code indicates a drainage issue or compressor protection activation due to over-temperature or low refrigerant pressure. Symptoms may include the unit stopping cooling or running, and the compressor may not engage or frequently cut out. If you notice heat at the outdoor compressor housing, this could further signal a problem.

Common Symptoms:

  • Unit stops cooling or stops running and displays P2
  • Compressor not engaging or cutting out frequently
  • Possible heat at outdoor unit compressor housing

Possible Causes

  • Compressor over‑temperature protection triggered (medium)
  • Low‑pressure protection / refrigerant issue (low)

How to Fix Error P2

DIY Fix Basic checks and reset

  1. Turn off the air conditioner and disconnect power for 10–15 minutes to allow internal protections to reset.
  2. Check that outdoor unit coils and ventilation are free of debris or blockage.
  3. Inspect visible refrigerant line insulation and ensure airflow around outdoor unit isn’t restricted.

Technician Only Compressor and refrigerant system diagnostics

  1. Measure compressor head and top temperatures during operation to confirm overheating.
  2. Check refrigerant pressures and inspect for leaks with proper leak detection tools.
  3. Verify operation of overload protector or high‑temperature sensor on compressor.
  4. Inspect and test outdoor main PCB and inverter protection circuits for faults.

Parts needed: Compressor temperature sensor/overload protector, Refrigerant lines and service valves, Outdoor unit PCB / inverter protection module

🛑 When to Call a Pro:
  • Error persists after power reset and basic airflow/ventilation checks
  • Unusual compressor noise, visible oil on lines, or heat at compressor housing
  • Low cooling performance with suspected refrigerant issues
