Error Codes (undefined): Troubleshooting, Fixes & Prevention Tips explained below.

What Does CH36 Mean?❓

CH36 means your AC has detected a refrigerant leak in the cooling system. Refrigerant leaks reduce cooling efficiency, increase energy consumption, and can damage the compressor if not addressed. This safety feature protects the AC from operating under harmful conditions.

air-conditioner - Causes of CH36 Error

  • Damaged or corroded refrigerant lines
  • Loose joints or pipe fittings
  • Poor installation causing micro-leaks
  • External impact or vibrations damaging copper pipes
  • Use of incorrect refrigerant type or overcharging

  • Leak Detection

    1. A qualified technician uses leak detectors or soap solution to locate the leak.
    2. Check both indoor and outdoor unit piping.

  • Seal or Replace

    1. Seal minor leaks or replace damaged pipes, valves, or coils.
    2. Ensure all joints are tightened and tested.

  • Vacuum and Recharge

    1. Evacuate air and moisture using a vacuum pump.
