Since you mention that it makes a different sound, I would suspect a shorted high voltage diode or a bad magnetron.

Does not heat up food everything else is OK i think that the rack touch the door when i was using it


Double check and make sure that the rack did't scratch the paint inside the cavity. Could be two possible reasons for it not to heat. Could possible be the magnetron or the diode. Normal when the magnetron goes bad, the microwave will still sound almost normal, bit just wouldn't heat. when the diode goes bad the microwave tends to make a humming sound when turned on

Our microwave looks and sounds to be operating normally, except that nothing becomes heated despite using different pre-set or manual modes.


If it sounds normal and not heating, you may need to replace the magnetron. this is a very common problem and normally occurs from the overheating of food.
if the microwave is making a gumming noise, then the diode needs to be replace.

Generally, the most common causes of a failure to heat are:

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose conneciton on the control unit circuit board
- bad magnetron or other high voltage part
