Aircon Error Code Lookup
Use this when your aircon shows an error code or blinking light. Start with the brand, then check severity, reset limits, and the next test to ask about.
Choose Your Brand
Start with the brand on the unit or remote. The code meaning, severity, and reset advice all change by manufacturer.
How To Use An Error Code
Treat the code as a direction for checks, not a finished diagnosis.
Read it as what the unit detected
A drain, sensor, pressure, or communication warning still needs checks to confirm the actual cause.
Stop after repeated resets
If the same code returns within one cooling cycle, more resets just stress the compressor or PCB.
Ask what test result supports it
Useful checks include pressure, amp draw, continuity, resistance, drainage flow, or visible corrosion.
