FYI, if you have an electric coil stove the elements wear out over time but they're super easy to replace - you basically just unplug it and plug in a new one and they're pretty cheap, you can get a set of 4 for US$35.
It's doable but it's more work and the heating elements are not standardized/common, you'll have to get the right part from the manufacturer (assuming they still make it for your stove model).
