Electrolux Air Conditioner Error Code H6

H6 is an indoor fan motor locked or blocked protection code. It activates when the control board detects that the DC fan motor has stalled or is not returning the expected PG feedback signal. The unit shuts down to protect the motor and driver circuitry from damage. The fault must be diagnosed and resolved before the unit will resume normal operation.

No. The H6 code means the indoor fan is not operating correctly, which prevents proper airflow across the evaporator coil. Continuing to run the unit in this condition risks ice formation on the coil, compressor damage from liquid refrigerant, and potential overheating of the motor driver components. The unit should remain off until the fault is resolved.

A power reset may temporarily clear the H6 code and allow the unit to attempt a restart, but the fault will return if the underlying problem has not been corrected. If the motor is stalled due to a physical obstruction or a failed bearing, resetting without addressing the cause can cause further damage. Resetting is useful as a first step only after verifying that the fan blade spins freely and all connectors are secure.

Some H6 causes are DIY-accessible, such as clearing a physical obstruction from the fan blade or reseating a loose PG feedback connector. However, testing the motor control terminal output voltage and replacing the motor or control board require electrical knowledge and appropriate tools. If basic checks do not resolve the fault, a qualified technician should complete the diagnosis.

Repair costs vary depending on the root cause. A simple connection repair or cleaning may cost between $75 and $150 in labor. Replacing the indoor DC fan motor typically runs between $150 and $350 including parts and labor. If the main control board requires replacement, costs can range from $200 to $500 or more depending on the model.
