Name: Samsung DOP36M96GLS
Brand: Samsung

Question 1

What does error code C-20 mean on Samsung DOP36M96GLS?

Accepted Answer

Oven sensor open (over 2950 ohm) or oven sensor short (under 930 ohm). Cause: Oven temperature sensor open circuit; Oven temperature sensor shorted; Damaged wire harness between sensor and Main PCB; Faulty Main PCB at connector CN320.

Question 2

What does error code C-21 mean on Samsung DOP36M96GLS?

Accepted Answer

Oven internal overheating — oven temperature reaches 650 F (343 C) in any cooking function except self-clean. Cause: Oven temperature sensor malfunction; DLB relay stuck on; Broil relay stuck on; Bake relay stuck on; Disconnected or damaged harness linked to Main PCB.

Question 3

What does error code C-30 mean on Samsung DOP36M96GLS?

Accepted Answer

PCB sensor opened or PCB sensor shorted (onboard NTC thermistor fault). Cause: Onboard PCB NTC thermistor open or shorted; Faulty oven temperature sensor; Damaged harness connections at CN320 on Main PCB.

Question 4

What does error code C-31 mean on Samsung DOP36M96GLS?

Accepted Answer

PCB sensor temperature high — onboard PCB NTC thermistor reading abnormally high temperature. Cause: PCB NTC thermistor failure; Faulty oven temperature sensor causing runaway.

Question 5

What does error code C-d0 mean on Samsung DOP36M96GLS?

Accepted Answer

Short key — short circuit detected at control interface at connector CN300 on Main PCB or Sub PCB. Cause: Wire harness not properly inserted into connector of Main PCB or Sub PCB; Short circuit between Main PCB connector CN300 pins.

Question 6

What does error code C-d1 mean on Samsung DOP36M96GLS?

Accepted Answer

Door locking information — door lock motor or switch malfunction. Cause: Harness not connected properly with door lock switch and motor; Door lock motor coil resistance abnormal; Door lock switch not working; Main PCB relay fault.

Question 7

What does error code C-F0 mean on Samsung DOP36M96GLS?

Accepted Answer

Main PCB to Sub PCB communication error. Cause: PBA program version mismatch between Main and Sub PCB; Wire harness disconnected between Main PCB CN470 and Sub PCB CNS200.
