Haier · Hydro Split & All-in-One Systems
This error indicates a problem with the upper DC fan motor, specifically if its operation is below 20 rpm for 40 seconds or less than 20% of the target value. If this occurs 3 times in an hour, the failure will be confirmed as unresumable.
Click steps to track your progress.
Turn off the main power to the Haier unit at the circuit breaker.
Visually inspect the upper fan for any physical obstructions (leaves, debris) and remove them.
Attempt to gently rotate the fan blades by hand to ensure they move freely.
Restore power and restart the unit. If the error persists or recurs frequently, contact a qualified service technician.
