We have the service manual for this model and have uploaded it to our site here to help you. You will need the free Adobe Reader to view or print it.


The first thing to check would be the door switches.

Then I would check the high voltage components. Here are some links you or someone you know can use for test help, but read their safety warnings first:

Opening the door tripped breaker a few times, now microwave will not power on.


Sounds like a bad switch should have three primary, secondary, and monitor switch after 5 years change all 3 they are not the same primary and secondary are NO ( normally open ) and the monitor NC ( normally closed ) unit will not come on the fuse on the filter board is blow this usually shorts out the filter board change the switches first and replace fuse may not have to replace filter board hopes this helps.

This microwave was working perfectly last night and doesn't even look like it has power today. We have done nothing to it. Please help. It is a Kenmore 721.62624200.


First, check to see if the circuit breaker has tripped. Then check to make sure it is firmly plugged in to the outlet. After that, it is time for a technician.

Magnetron is gone, just to be sure remove the microwave and use on a different socket. sometimes the breaker becomes faulty after 10 AMPS.

New microwave stopped working after 15 seconds


Possibly the fuse / breaker is tripped, usually all outlets in one room share same breaker. Check breakers (or fuses) or try outlet in differnt room. If the outlet has power, (plugin a lamp to check) and the microwave still does not work, take it back to store for replacement or refund.

Microwave doesn't start but the interior light goes on when you hit the start button


Hello

Remove the plug from the wall outlet and wait about 10 seconds before re-inserting it. The plug must be firmly inserted to transfer electricity to the appliance.


Open your home's circuit breaker box and reset the breaker if it has tripped and is set to the "Off" position. Simply slide the breaker over to the "On" position to fix a breaker that has tripped.


Plug a different appliance into the same outlet to make sure the outlet you are using is functional. Plug the microwave into a different outlet to see if this yields different results.


Press on the microwave door to ensure it is completely closed. The microwave will not function until the door is fully shut.


Press the "Start" pad on the display panel after setting the time. Failing to press this will result in the microwave not knowing that it should start.


Press the "Stop/Reset" pad on the panel if a program different from the program you want to run has already been entered into the system.


Press the "Clock" pad three times to turn off the demo mode. The demo mode will not allow the appliance to turn on and cook as it should.

Powers on will not work


Check the breaker . A microwave oven should have a dedicated circuit plug a lamp in the oven plug in if it comes on you have another problem if it wont come on flip the breaker they can trip just enough that you cant see it is tripped flip it all the way off then flip it back on again see if it works. You might have to do this a few times even if light clock comes on it might be tripped just enough to not let enough power come through use a multi meter if you have one to check the current.

Microwave quit working


If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

It may also be the high-voltage rectifier diode.

If you or a friend decide to look into it, we have critical safety information and disassembly information at our site, linked here on Fixya: http://tinyurl.com/yzjozk

Feel free to post your brand and model so we might be able to give me specific info.
