Two years later, the light begins flickering. Now it just doesn't come on at all.
I google up how to replace the lightbulb. Turns out, you can't and this issue is common amongst owners of these microwaves. It's amazing they can't spend the extra dollar or two in components and make the bulb replaceable. I imagine a lot of these Toshiba microwaves are in dumps now.
I'd have a hard time trying to give this thing away with a defective light. I'll probably be stuck with it finally stops working altogether, and then it will end up in a landfill.
