Electrolux refrigerator error codes: a door left open, a power blip, or the one fan behind the freezer wall.

Not a fault by itself. The freezer went above 26°F or the fresh-food section above 55°F for more than an hour — a door left open, a long outage, or a box still pulling down after it was first plugged in.

1. Every door and drawer is shut and nothing inside holds one open — a bag, a shelf pushed out, a bin not seated.
2. The gaskets seal: shut a dollar bill in the door and pull; it should drag all the way round.
3. The box is cooling: a hand on the back wall of the freezer feels cold, and the fan runs when the door switch is pressed in.
4. A refrigerator just installed or just moved needs 24 hours to reach temperature; the alarm clears on its own.

Press Alarm Reset to mute it; it stays lit until the section is back in range, then goes out by itself. A box cold at the back wall and warm up front is airflow — pull the box out and let the air through behind it. A box that never gets cold with the doors shut is a fault, not a state — see SY EF, or a sealed-system call.

Not a fault. The power went out while the refrigerator was running; the light or the letters stay on so you know the food sat warm for a while.

1. Press Alarm Reset (or Set) once the power is back. After a long outage the high-temperature alarm shows too — it clears once the box is cold again.

Nothing to fix. PF with no outage is a plug loose at the wall or a breaker that is tripping — look at the cord at the outlet.

Not a fault. The lights and the panel work and nothing cools — the cooling system has been turned off from the panel, the way a store floor shows the controls, or by a key held by accident.

1. The display reads OFF where the temperatures should be, and the box is warm with the lights on.

Press and hold the key the panel marks for cooling On/Off (on most IQ-Touch panels the On/Off key, held about 3 seconds) until the temperatures come back and the compressor starts. Give it 24 hours to reach temperature.

Not a fault. The display shows Sb and the lights, the dispenser and the tones are off; cooling continues and the high-temperature alarm stays armed.

1. Press and hold the – (minus) key and the Temp °F/°C key together for 5 seconds; the display returns to the temperatures.

The refrigerator is back to normal. On a panel laid out differently, the use-and-care names the two keys — held 5 seconds either way.

Not a fault. The water filter light comes on at about six months, and the air filter light at about six months, on a timer — not on a measurement of the filter.

1. Replace the filter (the plate inside the fresh-food section names the type), then press and hold the Filter Reset key — Water Filter or Air Filter, the panel prints which — for 3 seconds until the light goes out.

The light goes out. A dispenser that trickles after a new water filter has air in the line — run a gallon through it.
