Electrolux Split AC Error Code E2 — What It Means & How to Fix It

What Does This Error Mean?

The indoor coil has become too cold and icing is about to occur. Your AC has paused cooling to protect the coil from freezing. This is often caused by a dirty filter or low refrigerant.

Affected Models

Electrolux EXH09HL1W
Electrolux EXH12HL1W
Electrolux ESV09CRK
Electrolux EWHI09
Electrolux Inverter Split System

Common Causes

Clogged or dirty air filter restricting airflow over the indoor coil
Low refrigerant level causing the coil to run too cold
Indoor fan motor running slowly or failing
Blocked return air vents reducing airflow to the unit
Very low room temperature combined with AC set too cold

How to Fix It

Turn the AC off immediately and let it sit for at least 30 minutes.

This allows any ice that has formed on the coil to melt safely before restarting.
Remove and clean the air filter under warm running water.

A blocked filter is the most common E2 cause. Clean filters restore airflow and prevent re-icing.
Check that all supply and return air vents in the room are open and unobstructed.

Furniture or curtains blocking the indoor unit prevent warm room air from reaching the coil.
Set the fan speed to High and run the AC in Fan-Only mode for 15 minutes.

Fan-only mode circulates room air without running the compressor, helping clear any residual ice.
Restart cooling and monitor for recurrence of E2 over the next hour.

If E2 returns within an hour, the unit likely has low refrigerant and needs a technician.

When to Call a Professional

Call a technician if the error returns after cleaning the filter and the unit has been off for 30 minutes. Low refrigerant cannot be fixed by the homeowner — refrigerant handling requires a licensed technician. Fan motor replacement also requires a professional.

Frequently Asked Questions

Is E2 dangerous for my Electrolux AC?

E2 itself is a protective shutdown — the AC stops before serious damage occurs. However, if you keep restarting it without fixing the root cause, ice can block the coil completely. Leave it off until you have cleaned the filter and allowed it to defrost.

How do I clean the filter on my Electrolux split AC?

Open the front panel of the indoor unit and slide out the mesh filter. Rinse it under warm water, let it dry completely, then reinstall. Clean filters every 2–4 weeks during heavy use.

My filter is clean but E2 keeps coming back. What is wrong?

If the filter is clean and E2 persists, the most likely cause is low refrigerant. Low refrigerant makes the coil run far colder than it should. This requires a licensed technician to recharge the system.
