Got the oven about 6 months ago. Worked without problem until a couple of nights ago. Now whenever I plug it in it immediately trips the breaker. The oven is in all likelihood still under warranty but I’d like to make sure it’s the oven and not the thing it’s plugged into.

I opened the plug and everything is connected the way it should be, without any exposed wires touching each other.

If I unplug the oven, the protection device shows normal signal lights and doesn’t do anything to the breaker.

Is this a known problem?
