Kettle lights but doesn't boil

Most likely the thermo fuse is blown.

You have to take the kettle apart and see the spec for the thermo fuse. You can get these at most any electronics parts supplier for appliances.

To change the thermo fuse you will need the proper crimp type connectors and the crimp tool. This is not able to be soldered. It runs too hot, and soldering in a circuit close to a heating element is not able to be used.

Before changing the thermo fuse, you can test it with an ohm meter. It should typicaly read about 0.1 to 0.2 ohms. The heating element resistance should typicaly read about 8 to 12 ohms.

If the heating element reads below 6 to 7 ohms on a well calibrated ohm meter, or above 15 ohms, it is defective.

If the thermo fuse is blown, the kettle may have been left running when boiled out and over heated, or there is a short in the heating element.

If you feel that you are not comfortable to do this type of repair, it would be best to give the kettle out to an appliance service centre to have it serviced.

When you change the thermo fuse, and if it blows again the heating element is probably damaged. It must be replaced if possible, or if worth the cost.

On the other hand, if the kettle is more than a few years old and you don't want to go to all this trouble, you may want to consider to simply get a new one.
