Suddenly microwave stopped working


(would really like more info- digital number dead as well?)

(assuming completely dead) Could be a couple of things:
- blown fuses (inside, relatively easy to replace, std size avail at Raioshack) <-- most likely
- cut/loose power cord connection inside.
- (unlikely but worse case scenario) Door was closed crooked- one tong hit one door switch before the other- causing a short circuit internally that "self destructs" the microwave to prevent it ever operating with an open (or even crookedly ajar) door, irradiating any users. Typically it just blows the fuses, but if fuses blow immediately upon replacing and turning power on, then possibly one of the switches fused or melted internally, and needs to be replaced.

My countertop microwave stopped working. What was the problem? Can you help?


If it is completely dead, no light, motor or keypad, it's probally a blown line fuse. Open up the cabinet and you should be able to find a fuse near the power cord. An appliance supply house should be able to get you a replacement.

The microwave stopped working. It will not turn on and the outlet is functional


If it is completely dead, meaning, that the display, keypad, oven light does not work. The problem is most likely that the line fuse is blown. Remove the cabinet screws and remove the cabinet. The fuse should be close to either the power cord or the electrical circuit board. Replace with the same type of fuse.

My GE1340 built-in microwave stopped working completely. It is just dead and does not respond when you push buttons. No power. Checked circuit breakers - all are fine. Any ideas? Is it kaput?


There is usually a 125V, 20 AMP line fuse inside most microwave ovens. It will be mounted at the point where the power cord enters the back of the unit, in line with the power cord, or on a small circuit card called a line filter. Unfortunately, you will need to uninstall the oven (if this is an over the range model), UNPLUG it and remove the exterior case to access. The case comes off in various ways depending on manufacturer and model. Parts are available at any of the following websites: searspartsdirect.com pcappliancerepair.com appliancepartspros.com repairclinic.com The first three sites include illustrated parts listings that can help you locate and properly identify any parts you may need. The microwave oven may also equipped with various thermostats that (if blown) can cause similar symptoms to that of a blown line fuse. So, if the line fuse is NOT blown, you may want to check all the thermostats to see if they are still good. You will need to remove each one and measure across the terminals with a multimeter. A good reading is 0 ohms. NOTE: The thermostats typically will trip if the oven cavity has been overheated. Cooking items that are high heat producers such as popcorn or baked potatoes in rapid succession can often cause this problem. Allowing the oven cavity to cool a few minutes with the door open between cooking can prevent this from occurring.


If the line fuse is blown, you can usually purchase a box of fuses at a hardware store for just a little more than what the manufacturer charges for a single fuse. 125V, 20AMP Ceramic Slow Blow fuses are recommended.

If you have any questions, or need additional assistance troubleshooting, please post back with your MODEL NUMBER and let me know. I hope you find this information helpful.

NOTE: Make sure you take any resistance readings with the microwave UNPLUGGED and the component under test isolated (removed) from the circuit. These ovens can blow a fuse by simply sitting idle. This can occur from any power fluctuations, brown outs, voltage spikes, etc. Or, it could be the symptom of a component that may have failed. If you find the internal fuse blown and replace it, only to have it blow again, you have a more significant problem than a simple blown fuse.

NO POWER


Most likely have blown a fuse , get behind the touchpad to ohm the fuse out , replace if blown , if continues to blow check componets for shorts , there will likely be signs of burnt parts.

Danby 1000 Watt Microwave is completely dead. Just stopped working right after heating up a dinner.


you may have just blown a fuse inside the microwave or the transformer inside has now failed and will need replacing but it will need to be looked at to see what exactly happened

If it's dead, it's probably a blown fuse or maybe a blown thermalcouple fuse. a bad magnatron won't make the unit apear dead unless its blowing fuses.

Hope that helps..

Kenmore elite microwave


Does the digital display light up at all? Is it completely dead? Are you sure it has power? Have you tried another outlet? If the outlet is good and the unit is completely dead, the internal fuse may have blown. You can try to take the cover off (with the unit unplugged) and look for a blown fuse. Try replacing the fuse with an EXACT fuse of the same rating. Try plugging the unit back in again and see if the unit comes back on. If not, you may have a power supply issue or defective Magnetron.

Please let me know what you find and we'll go from there.

Good Luck,
- Jim
