Name: Samsung NX58J7750SS
Brand: Samsung

Question 1

What does error code -dC- mean on Samsung NX58J7750SS?

Accepted Answer

Divider sensing information — Flex Duo divider insert or remove state mismatch. Cause: Divider present in single mode or absent in twin or double mode; Housing connector disconnected; Failed divider sensing switch.

Question 2

What does error code C-20 mean on Samsung NX58J7750SS?

Accepted Answer

Oven sensor opened (over 2950 ohm) or oven sensor shorted (under 930 ohm). Cause: Failed oven temperature sensor; Damaged terminal or wire on harness between sensor and CN301 on Main PCB; Open or shorted sensor circuit.

Question 3

What does error code C-21 mean on Samsung NX58J7750SS?

Accepted Answer

Oven heating over — oven temperature has risen excessively, triggered at 650 F (343 C) in any cooking function except self-clean. Cause: Failed oven temperature sensor; Shorted heater relay on Main PCB (broil, bake, or convection relay); Disconnected or damaged harness to Main PCB; Divider switch off with divider inserted.

Question 4

What does error code C-30 mean on Samsung NX58J7750SS?

Accepted Answer

PCB sensor opened or shorted — oven sensor error at PCB side. Cause: PCB-side sensor circuit open or shorted; Failed oven temperature sensor; Poorly seated connectors CNP207, CNP208, or CNP209 on PCB.

Question 5

What does error code C-31 mean on Samsung NX58J7750SS?

Accepted Answer

PCB ambient temperature high — safety error. Cause: PCB overheating due to environmental conditions or failed cooling; Failed oven temperature sensor causing runaway heating.

Question 6

What does error code C-A2 mean on Samsung NX58J7750SS?

Accepted Answer

BLDC motor operation information — cooling fan motor or air intake motor error. Cause: Wire harness disconnected to cooling or air intake motor; Failed BLDC motor (cooling fan or air intake); Failed Sub PCB.

Question 7

What does error code C-d0 mean on Samsung NX58J7750SS?

Accepted Answer

Shorted key — keypad short circuit detected. Cause: Keypad cable not properly inserted into Main PCB connector; Short circuit between Main PCB and connector or keypad and cable; Short circuit between pins on Sub PCB connector CN701.

Question 8

What does error code C-d1 mean on Samsung NX58J7750SS?

Accepted Answer

Door locking information — door lock mechanism error. Cause: Harness disconnected from door lock switch or door lock motor; Failed door lock motor coil out of spec; Door lock switch malfunction.

Question 9

What does error code C-F0 mean on Samsung NX58J7750SS?

Accepted Answer

Main-to-Sub communication error — continuous communication failure between Main PCB and Sub PCB. Cause: Harness disconnected between Main PCB CNS401 and Sub Display PCB CN200; Harness disconnected between Main PCB CN304 and Sub Fan Control PCB CN500; Incorrect firmware version on Main or Sub PCB.

Question 10

What does error code C-F2 mean on Samsung NX58J7750SS?

Accepted Answer

Main-to-Touch communication information — communication error between Main PCB and Touch PCB. Cause: Wire harness disconnected between Main PCB and Touch PCB; Incorrect firmware version on Main or Touch PCB.
