My Solution is:

Following this link, http://www.repairclinic.com/SmartSearch/SmartSearch.aspx, provides valuable D.I.Y. safety information on the make and model number of your appliance. In order to access your product information, you will need to enter the model number stamped on the manufacturers product information data tag, located on the unit.

Note: A volt-ohm meter is beneficial in performing electrical tests.

Thank you for providing a valid model number!


From your description, it sounds as if 1 or all of 3-4 door switches has failed. Using the link supplied above, you can view a page with these switches. The link below shows an exploded view of the service area. Using an ohm meter will help find the faulty switch.

How to set the digital clock pls


Without your model number this is a GENERIC answer that is applicable to MOST microwave ovens.
1. Press Stop//Pause
2. Press Clock
3. Set Time
4. Press Clock

Time is now set and the Microwave is ready for use.

If this does not work.. I need you to respond with your model number to look up your exact steps.

Thanks for choosing FixYa,

My microwave displays time etc, but does not turn on


That model number from the tag on your oven should be KCMS1555SS0, KCMS1555SS1, or KCMS1555SS2.

We would need more detailed information about what it's doing or not doing.

Does it respond to key presses?
Does the inside light come on when you open the door?
Can you enter the cooking time?
What happens when you press "Start"?
Does it run but not heat?
Does it count down but the inside light and fan do not come on?

Please post a new help request with the model number and detailed sympotms.

Round soft key OXO Timer I need to change the clock time their model # is 1061978


Operating functions:
To set the clock, press and hold the clock/timer button for three seconds. A clock icon will appear on the left side of the screen. Input the time using the numerical buttons and then click the clock/timer button to save the time.
To set the timer, press and release the clock/timer button so that the display shows all zeroes. Enter the desired time using the keypad. Press start/stop to start the countdown. The countdown may be paused by pressing the stop/start button and resumed by pressing the same button again.
When countdown is complete, timer will beep continuously for thirty seconds and display will flash. Timer will then beep every ten seconds for ten minutes until the stop/start button is pressed.
This timer will also time up to time activities. To start count up, press clear/memory so timer reads all zeroes. Press stop/start and a plus sign will appear on the right side of the screen as the timer begins counting up.

When I press the clock button, the microwave turns on and starts counting down from 30 seconds. The stop/clear button will not work to stop it. I have to open the door to stop it. I unplug it but it...


Hello :

It could be bad door switch or loose door switch mount . There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly .


good luck .

The clock works & counts down but the microwave won't heat


  • Disconnect the power for 30 seconds. After restoring power, do not set the clock.
  • If your model has an ON/OFF clock display, you can choose not to have the time displayed. To choose this option, press the 0 pad for about three seconds. To Turn the display back on, press the 0 again.





Touch the clock pad. Enter in the correct time of day by touching the numbers in sequence. Touch the clock pad again.

You need to trace the power feeding the high voltage transfomer. Because the table doesn't turn, it implies that a door switch or safety interlock is the problem.
