Samsung refrigerator error codes: most of them are a fan iced over, or the ice maker.

The fan behind the back panel of the fresh-food section is not turning at the speed the control asked for. On most Samsung French doors it has iced solid.

1. The doors — a door left ajar overnight, or a drawer or a jar holding a door off its seal, lets in the moist air that becomes the ice. Shut each door and feel the gasket all the way round for a gap.
2. The back panel inside the fridge — frost on the panel, a sheet of ice at the bottom of it, or a humming, scraping fan behind it, is the fan hitting ice.
3. The fridge temperature — a fridge that has crept to 45°F with the freezer still at 0°F is this fault nine times in ten.

Unplug the refrigerator, open both doors, put towels down and let it thaw for 24 hours — everything out, the ice behind the panel must melt completely (a hair dryer on low speeds it; never an ice pick). Plug it back in. A fan that spins freely once thawed was the ice; one that stays silent is the fan motor. A fridge that ices over again within weeks has a defrost fault behind it (the parts under 25C) or a gasket that will not seal — service.

The fan behind the back panel of the freezer is not turning at the speed the control asked for — ice on the blades, or the motor.

1. The freezer door seals all the way round; a bag of frozen peas behind a drawer holds the door off.
2. Frost on the freezer's back panel, or a buzz and a scrape from behind it, is the fan in ice.
3. The freezer temperature is rising while the fridge holds — the freezer fan's own sign.

The same 24-hour thaw as 22C — unplugged, doors open, towels down, everything out. A fan quiet and free after the thaw was the ice. One that never spins is the motor, and a freezer that ices again within weeks has a defrost fault (24C's parts) — service.

The fan at the bottom back of the refrigerator, beside the compressor, is not turning. Without it the compressor overheats and the whole box warms.

1. Pull the refrigerator out and take off the lower back cover (a few screws). Look for a mat of dust and pet hair on the fan and the coil beside it.
2. Something fallen behind the fridge — a cereal box, a dish towel — resting against the blades.
3. With the cover off and the fridge running, the fan should spin steadily; blades that turn by hand but never under power are the motor.

Vacuum the coil and the fan, clear whatever was resting on the blades, put the cover back and reset. A fan that is clean, free and still silent is the condenser fan motor — a part a technician replaces from the back.

The defrost heater behind the freezer's back panel did not warm, or the sensor that watches it never saw it warm. The freezer coil ices over and the airflow stops.

1. Reset (unplug one minute), then run the self-check again after a day.
2. Frost thick on the freezer's back panel and a freezer warming slowly over a week fits this code.

A defrost code that returns is the defrost heater, its thermostat (the bimetal clipped to the coil) or the defrost sensor — parts behind the back panel, a technician's job. A thaw buys a few weeks; it does not fix it.

The defrost heater behind the fresh-food section's back panel did not warm in its cycle, or its sensor never saw it warm.

1. Reset (unplug one minute), then run the self-check again after a day.
2. Ice on the fridge's back panel, water pooling under the crisper drawers, or ice under the drawers — the drain under the coil has frozen along with it.

A returning 25C is the fridge defrost heater, its thermostat or the defrost sensor — behind the panel, a technician's job. A full thaw is the stopgap, not the fix.

The sensor that tells the control the fridge coil has finished defrosting reads open or shorted. The control cannot run the defrost without it.

1. Reset (unplug one minute) and run the self-check again after a day.

A sensor code that returns is the defrost sensor or its connector behind the fridge's back panel — a part a technician replaces.

The control drove the compressor and it did not start, or it locked. The box stops cooling.

1. The refrigerator is plugged straight into the wall — never an extension cord.
2. Unplug it for five full minutes, plug it in, and listen at the bottom back: a steady hum after a minute is the compressor running.

A compressor that stays silent after the reset, or hums and clicks off every few minutes, is the compressor or its inverter board — a service call. Move the food if the box warms; do not keep resetting it.

The power coming in dropped below what the control will run the compressor on. A brownout, or a weak circuit.

1. The refrigerator is on its own outlet — never an extension cord or a power strip.
2. A lamp on the same circuit does not dim when the compressor starts; if it does, the outlet or the house wiring is the problem — an electrician's.
3. Was there a storm or a utility brownout? The code clears with the one-minute unplug once the power is steady.

Fix the supply and reset. A refrigerator on a sound outlet that keeps printing 85C has a fault on its own board — a service call.

Not a fault. The lights and the panel work but the compressor is switched off — the mode a store floor uses. It turns on by a button press, usually by accident.

1. The display reads OF OF (or O FF) where the temperatures should be, and the box is warm with the lights on.

Press and hold the two buttons the manual names for Cooling Off — Energy Saver and Fridge on most models, Freezer and Fridge or Power Freeze and Fridge on others — for about three seconds until the temperatures come back and the compressor starts.

Not a fault on its own. The panel lit every segment after a power blip, or while the main board and the display were re-connecting.

1. Unplug the refrigerator for one full minute and plug it in; the temperatures come back.

A panel that stays on 88 88 after the unplug, with the refrigerator cooling normally, is the display board or its harness — service, but the food is safe meanwhile.

The Family Hub screen lost touch with the refrigerator's own control, or its software stalled.

1. Restart the screen: press and hold the power button on the top right edge of the screen for a few seconds and choose Restart (or until it goes dark, then press again).
2. If the screen stays dark or frozen, unplug the refrigerator for one full minute.
3. Let the screen finish any update it offers; a half-installed update prints this code.

A screen that answers after the restart was a software stall. One that stays frozen or dark, or prints 41C again within the day, is the screen's board or the harness in the door hinge — a service call. The refrigerator keeps cooling meanwhile.

The control cannot talk to the display in the door. On a French door it shows when the harness through the top hinge has been disturbed — a door taken off for a move, or pulled through a doorway.

1. Was a door removed or the refrigerator moved recently? The connector sits under the small cover on the top hinge of the left or right door.
2. Unplug the refrigerator, lift the hinge cover (one screw), and look at the connector — it should be pushed home with its latch clicked, no pins bent.
3. Plug it back in; the code clears at once if the connector was the cause.

Seat the connector and the panel comes back. A connector seated and latched that still prints PC ER is the harness through the hinge (a wire broken from the door swinging) or the display board — a technician's job.
