Samsung Refrigerator Error Code PC ER: Meaning and Fix
Also shown as: PC CH
Reading the refrigerator display
On a refrigerator the code shows on the control panel or dispenser display. Some models flash a letter or alternate two characters; hold the code in view and note both. Samsung codes combine a digit with a letter, and some alternate with the cycle time.
Samsung displays numeric-plus-letter codes such as 4C, 5E or 21E, and many models run a Smart Care self-check through the app. Washers and dryers often use letter pairs, refrigerators use number plus E. The codes apply to model numbers such as DW80R5061US, DW80K7050US and DV45T6000EW; check the label on your unit to confirm yours.
