Samsung Oven light not turning off: Common Causes & How to Fix
1Range/Stove/Oven Light Switch
Most Common Solution
Repair Instructions:
The light switch is responsible for supplying power to the light. If the switch is shorted, or faulty, the light will remain on. You can check the light switch using a multimeter, a tool used to test electrical continuity, meaning electricity can flow through it. If the multimeter shows that the light switch has continuity even when it's supposed to be off, this indicates that the switch is defective and you'll need to replace it.

2Range/Stove/Oven Door Switch
Common Solution
Repair Instructions:
The door switch in your oven is an important part that affects when the oven light goes on and off. Here's why: The door switch keeps things safe by making sure the oven light only comes on when you open the oven door. But if the door switch has a problem, it might not tell the oven when to turn the light off. So, even when you close the door, the light might stay on, which can be annoying, and it's a waste of electricity. That's because the oven thinks the door is always open, even when it's not. Fixing the door switch is important to make sure your oven light works the way it should and doesn't stay on when you don't need it.
