  • Official Samsung troubleshooting focuses on proper flame shape and cleanliness to maintain flame, and cleaning/assembly adjustments are often recommended before part replacement.

Possible Causes

Part: Burner assembly (ports)

Faulty flame safety/supervision device (thermocouple/flame sensor)

How to Identify: Flame lights then shuts off quickly; safety device isn’t detecting flame due to dirty, misaligned, or defective sensor

Part: Flame safety valve/thermocouple/flame sensor

Gas supply issues (pressure or partial blockage)

How to Identify: Flame weak, unstable, or extinguishes; check for gas supply valve not fully open, kinked/blocked line

Part: Gas valve/gas line

Incorrect gas pressure/adjustment or internal control fault

How to Identify: Persistent flame issues after cleaning and ignition checks, possibly uneven flame pattern

Part: Gas regulator or internal gas control valve
