My microwave oven isn't heating my food. Everything else works, the fan, the lights and the keypad. The microwave turns and sounds like everything is working but the food won't get hot. We used it about an hour before it stopped heating and everthing worked just fine. It is less than a year old. Any ideas?

Small component called a diode. Open up the microwave and try to find a black (usually) component that is most often connected between the magnetron (the thing that heats the food) and the chassis of the microwave oven (ground). I used to make a fortune replacing these! Costs about 5 bucks most appliance supply stores. Make darn sure you get one of the same value.

If it's less than one year old, it would be fully covered under warranty and you should contact the manufacturer to get it fixed free.

Some have longer warranties, and that will be covered in your owner's manual.

that could be the fuse or possible relay

This is typical of a failed magnetron: the part which actually supplies the microwaves.

By their very nature magnetrons can fail without warning from the day of manufacture but the vast majority do last longer than the manufacturer's warranty. I have noticed a trend towards more frequent premature failure with increasingly powerful ovens.

If the magnetron has failed then there is nothing you can do to fix this as it must be replaced. It's also typically the most expensive single component in most ovens so is rarely an economic repair.

Your appliance should still be within the manufacturer's warranty so you should follow their advice regarding getting the oven repaired. If you're in the UK then you have Sale of Goods Act protection for up to six years from the purchase date and if you wish can insist that the retailer replaces the oven or refunds your money as the goods were not "of satisfactory quality".

give more time

Sounds like the magnatron tube or it's fuse.

built in 3/94 is it worth fixing how much for magetron

My Whirlpool microwave, over the stove, stopped working when my son used it to heat his food and a heavy sound came out, like something exploded in it. When I check it, there was nothing broke. Everything works fine except that it does not heat. I will appreciate any help
