1. Inspect the power cordUnplug the power cord and check for voltage at the outlet. Also inspect for damage, shorts, or burn marks that can be a possible safety hazard.
   
2. Bad door switchIf your microwave does not work at all and you know everything is plugged in properly and the outlet is functioning, then also check the door hooks and the door release button. Using a volt-ohm meter on RX1, check your terminals. When your microwave door is closed you should have a reading of zero. Once the door is open the reading should change to infinity. If these readings do not match up, replacement of the door switch is necessary.
   
3. Blown fusesTo determine if your fuse has blown out, which may attribute to your microwave not running, you need to pull the fuse out using a pair of fuse pullers. Lay it down and using a volt-ohm meter on RX1, check both ends of the fuse in question. If you do not get a reading of zero, then you will need to replace the fuse.
   
4. Bad fan motorLocate the fan and remove the leads. Again using the volt-ohm meter on RX1, check the terminals. If an infinity reading is displayed, it means that the fan has gone bad and requires replacement.
   

he most likely cause of this problem is a keypad on the control.

You can try the stop/clear keypad to silence the beeping.

You can put the controls into child lock and see if the intermittent beeping stops. The instructions to turn the child lock feature you have it in the owner manual . The child lock disables most keypads.

otherwise replace the control board.

God bless you

Does the display say anything?

If it says "F3" then you have a shorted keypad.

Please post a new question with full model number and more detailed symptoms.

You may need to replace the keypad. I found there was moisture causing the problem when we boiled water on the right side of our stove which is under the keypad. I let the microwave dry out for several days and now only use the left side of stove when we boil water and have not had the problem.

The problem is the keypad "short in the membrane" or the microprocessor control board.

the membrane gets dirt under them and shorts out the keypad,you may as well just replace the control board which includes the display and keypad on the same board

F2 on a KitchenAid mike usually means a Keypad short. Beware if it is a KHMS155LSS, it can self start on its own with a KeyPad short. A real stunning defect.

You have a shorted 2 pad on the keypad.

Since it's less than one year old, it should be fully covered under warranty. I'd suggest contacting the manufacturer to get it fixed free.
