Electrolux Air Conditioner Error Code HC

The HC code indicates a Power Factor Correction (PFC) protection fault. The PFC circuit, which includes a boost reactor and PFC capacitor, has triggered a protective shutdown due to a detected electrical fault. The unit will not operate until the underlying cause is identified and corrected.

No. The HC error triggers a protective shutdown specifically to prevent electrical damage and potential hazards. The components involved in a PFC fault operate at high DC bus voltages, and continued operation attempts with a failed component can damage the inverter board or cause a more serious electrical failure. Keep the unit off until it has been inspected and repaired.

The first step is to inspect the reactor (L) wiring for visible damage such as burned insulation or loose terminals, then measure the resistance of the PFC capacitor. A shorted capacitor will read near zero ohms. The reactor should also be checked for continuity to confirm the winding is not open. These checks should only be performed after the unit is fully powered down and the DC bus capacitors have been safely discharged.

Powering the unit off and back on may temporarily clear the code, but if the underlying fault in the PFC circuit is still present, the HC code will return almost immediately. A reset does not repair the failed component. The root cause, such as a shorted capacitor or damaged reactor, must be addressed before the unit will run reliably.

Repair costs depend on which component has failed. A PFC capacitor replacement is typically the least expensive repair, often in the range of $80 to $200 including labor. Reactor replacement can fall in the $150 to $350 range. Inverter board replacement is the most costly scenario, commonly ranging from $300 to $700 or more depending on the model and labor rates in your area.
