Samsung Refrigerator Error Code 33

Error code 33 on a Samsung refrigerator signals a functional error with the freezer compartment ice maker, referred to as Ice Maker (F). The control board has detected that the ice maker is not operating correctly, which stops ice production. The primary fix involves replacing the Ice Maker (F) assembly and then performing a power cycle by unplugging and replugging the refrigerator.

A power reset alone is unlikely to permanently clear error code 33 if there is a genuine hardware failure in the ice maker. Samsung's diagnostic process actually requires a power reset after replacing the Ice Maker (F) assembly to allow the control board to reinitialize communication with the new unit. If the error returns after a reset without replacing any parts, the ice maker assembly needs to be inspected or replaced.

If the repair requires replacing the Ice Maker (F) assembly, parts typically cost in the range of $80 to $200 depending on the specific Samsung model. If you hire a technician for the repair, total costs including labor generally fall in the range of $150 to $350. Costs may be lower if the fault turns out to be a wiring connection issue or an ice jam that does not require new parts.

Some cases of error code 33 can be resolved without parts by clearing a mechanical ice jam or firmly reseating the wiring harness connector on the ice maker. If those steps do not clear the fault, the ice maker assembly itself will need to be replaced. Replacing the ice maker assembly is a moderately involved repair that requires unplugging the unit, removing the ice bucket, and disconnecting the wiring harness, which many experienced DIYers can complete.

Error code 33 is specific to the ice maker function and does not indicate a safety hazard. The refrigerator and freezer compartments will continue cooling food normally while this error is active. The only loss of function is ice production, so there is no urgency from a food safety standpoint, though the issue should still be diagnosed and repaired.
