Samsung Oven C-20, SE (5E) Error or No Heat Fix: Igniter (#DG94-00520A)
Quick Answer: On a Samsung oven, error code C-20 means the Oven Temperature Sensor (#DG32-00002B) is out of range, while SE (or 5E) indicates a shorted touch keypad membrane. If a Samsung gas oven runs the fan and stays cold without lighting, the Flat Igniter (#DG94-00520A) has failed.

Frequently Asked Questions
Why does my Samsung gas oven say it's preheating when only the top broil burner is on?
Samsung gas ovens alternate between the top broil burner and bottom bake burner during preheat. When the bottom igniter (#DG94-00520A) dies, the top broiler gets the oven to ~175°F and then shuts off, leaving the oven lukewarm.
