The Most Common Samsung Refrigerator Error Codes

Error Code: 1E, 2E, 3E, 4E, 5E, 6E, 7E, 8E — Sensor Failures

These codes indicate a temperature or defrost sensor has failed. Each number corresponds to a different sensor:

• 1E / SE — Freezer sensor failure

• 2E — Fridge sensor failure

• 4E / 4C — Water supply issue (check if your water line is kinked or the shutoff valve is off)

• 5E / SE — Defrost sensor failure

• 6E — Ambient room temperature sensor issue

• 8E — Ice maker sensor failure

What to do: For sensor codes, first try unplugging the refrigerator for 5 minutes and plugging it back in. If the code returns, the sensor likely needs to be replaced. This is a straightforward repair for a technician — usually a 30–60 minute job.

Error Code: PC ER or PC Ch — Communication Error Between Doors

This is one of the most common Samsung French door refrigerator issues. It means the main control board has lost communication with the door panel.

What causes it: The wire harness in the upper left hinge has been pinched or broken (very common on models where the hinge wears the wires over time), or the door was opened forcefully and damaged the internal cable.

What to do: This is NOT a DIY repair. The wire harness runs through the hinge and requires disassembly. A technician can typically repair this in 1–2 hours.

Error Code: 88 88 or All Dashes — Control Panel Communication Loss

If your display shows 88 88 or just dashes, the main control board has lost communication with the display board. Unplug the refrigerator for 10 minutes. If it returns, the control board or display board likely needs replacement.

Error Code: OF F or O FF — Demo/Showroom Mode Accidentally Activated

Good news — this is NOT a broken refrigerator. OF F means your fridge is in demo mode (also called shop mode), which disables cooling while keeping the lights and display on. This sometimes gets triggered accidentally when holding certain buttons.

How to fix it: Hold the Energy Saver and Fridge buttons simultaneously for 3–5 seconds. The display should change back to normal temperature settings.

Error Code: 22E, 22C — Freezer Fan Error

This code means the freezer evaporator fan motor has stopped working. The fan circulates cold air throughout the refrigerator. Without it, your fridge may cool unevenly or stop cooling entirely. Food in the fridge section won't be cold but the freezer may seem fine. Do NOT ignore this — continued operation without the fan can damage the compressor.

Error Code: 33E, 39E, 40E — Ice Maker Errors

• 33E — Ice maker sensor failure

• 39E — Ice maker function error

• 40E — Ice maker function error (ice fan)

What to do: First, check that the ice maker arm is in the down (ON) position. If the code persists, the ice maker assembly may need replacement.

Error Code: 85C, 85E — Power/Voltage Issue

This means your refrigerator detected a voltage problem — caused by a power surge, a failing outlet, or an issue with your home's electrical supply. Plug the refrigerator into a different outlet or have the outlet tested. If the problem continues on multiple outlets, there may be an internal board issue.

Error Code: 41, 42 — Freezer Temperature Issues

These codes indicate the freezer is not reaching or maintaining target temperature. Common causes: dirty condenser coils, a torn door gasket, or a failing compressor. Pull the fridge out and vacuum the condenser coils. Inspect the door gasket for cracks. If those are fine, call a technician — a failing compressor is serious.

When To Call a Professional

Try DIY first:

• Demo mode (OF F) — easy reset

• 4E water supply — check water valve

• Minor sensor codes — try unplugging for 5–10 minutes first

Call a technician immediately:

• PC ER / PC Ch — wire harness damage

• 22E fan failure — compressor damage risk

• Any code that returns after a reset

• Any code accompanied by no cooling at all
