Many of the prematurely dead "Hamilton Beach" microwave ovens (sold only on Amazon and Walmart) could be revived just by replacing this one part. Same part is also used in many other appliances, but buying it from any of the appliance "makers" bumps the price at least 10 times higher. They can get away with overcharging because most people don't know that lots of appliance parts can be bought the same way as tires. No one buys new tires from their car's manufacturer because every spec needed to find an exact replacement (or better) is stamped right on the sidewall. And with appliance parts, you don't even necessarily need to know what those numbers mean. Just type them into Google and follow the clues.
