Electrolux Split AC Error Code H6 — What It Means & How to Fix It

What Does This Error Mean?

H6 means the indoor fan motor has stopped spinning or is not sending speed feedback to the control board. The AC will not cool or heat because it cannot circulate air safely. Check for obstructions in the indoor unit before calling a technician.

Common Causes

Foreign object (dust build-up, debris) blocking the indoor fan blade
Seized or worn indoor fan motor bearings
Faulty hall sensor not reporting fan speed to the control board
Loose or disconnected wiring between the fan motor and control board
Failed indoor PCB no longer sending the correct drive signal to the motor

How to Fix It

Turn off the AC at the remote and switch off the circuit breaker.

Never reach into the indoor unit while the fan could spin unexpectedly.
Remove the front cover of the indoor unit and inspect the fan blade.

Look for dust clumps, insects, or any object jammed against the blade.
Try spinning the fan blade gently by hand — it should turn smoothly with no resistance.

If it feels stiff, grinds, or will not move, the motor bearings may be seized.
Check that all visible wiring connectors on the indoor unit are firmly seated.

A connector loosened by vibration over time can cause intermittent H6 errors.
Restore power and restart the AC to see if H6 clears.

If the fan now spins normally and H6 is gone, an obstruction was the cause.
If H6 returns or the fan still does not spin, call a licensed technician.

Motor or PCB replacement requires proper tools and should not be attempted at home.

When to Call a Professional

Call a technician if the fan blade spins freely by hand but H6 still appears. A faulty hall sensor, motor winding, or PCB requires professional diagnosis and parts. Do not run the AC with H6 active — it will not cool and may overheat the indoor coil.

Frequently Asked Questions

Can I fix H6 myself without a technician?

If the fan blade is blocked by debris, clearing it may fix H6 immediately. If the blade spins freely but H6 persists, a sensor or motor fault requires a technician. Do not attempt to bypass the fan feedback — it protects the indoor coil from freezing.

Why does H6 appear even though I can hear the fan trying to spin?

The motor may be running but the hall sensor is not detecting speed correctly. The control board requires a speed signal — without it, H6 trips as a safety measure. A technician can test the sensor and determine if the motor or sensor needs replacing.

Will H6 damage my AC if I keep trying to restart it?

Repeated restarts will not help and may stress the motor windings further. The AC will shut down again each time the protection trips. Leave it off and arrange a service visit to avoid causing further damage.
