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: Possible causes include an open circuit or shorted oven temperature sensor, damage to the wire harness between the sensor and Main PCB, or issues with the Faulty Main 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: Causes may include an oven temperature sensor malfunction, or relays for broil, bake, and DLB being stuck on. Additionally, a disconnected or damaged harness linked to the Main PCB could be responsible..

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: The issue may stem from an open or shorted onboard PCB NTC thermistor, a faulty oven temperature sensor, or damaged connections at CN320 on the 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: Possible causes include a PCB NTC thermistor failure or a faulty oven temperature sensor leading to runaway conditions..

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: The issue may stem from an improperly inserted wire harness into either the Main or Sub PCB connector, or a short circuit between pins on the Main PCB's CN300 connector..

Question 6

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

Accepted Answer

Door locking information — door lock motor or switch malfunction. Cause: Possible causes include improper connection of the harness with the door lock switch and motor, abnormal resistance in the door lock motor coil, malfunctioning door lock switch, or a fault in the main PCB relay..

Question 7

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

Accepted Answer

Main PCB to Sub PCB communication error. Cause: The issue may stem from a PBA program version mismatch between the Main and Sub PCBs or a disconnection in the wire harness linking Main PCB CN470 to Sub PCB CNS200..
