Hello. If the internal fuse is blown it can be replaced. If you are handy you can check the fuse and replace it yourself, if not call your local microwave dealer and get an estimate.
Here is how to check and replace it yourself:
To get to the fuse, remove the outer cabinet of the unit, which is usually held in place with a few screws. Once the outer cabinet is removed, follow the power cord into the unit. It will take you to the fuse holder, where the fuse sits. The fuse holder is located two or three inches into the unit, and may be attached to a power board.
Decide if your fuse is blown. A blown glass fuse will produce flash burn marks on nearby surfaces, or it will be completely black on the inside. The internal fuse wire (filament) will be melted and blackened. Ceramic fuses give no outward signs of having blown. To determine if a ceramic fuse is blown, test it with an ohmmeter. If the ohmmeter reads zero ohms, your fuse is fine. A reading of infinite ohms means your fuse is blown.
Replace the blown fuse. Pop it out of its holder and snap in a new one. You can squeeze the fuse clips together with your fingers in order to tighten their grip. Replace the unit's outer cabinet, plug it back in, and test to see if it is running properly. DO NOT run the microwave with nothing in it.
NOTE: Fuses do not usually blow on their own. A fuse may blow because of problems with the interlock switches or with high voltage circuitry. It is also possible, though rare, that a power surge will cause a fuse to blow.

My Intellichef microwave model #K0936 has stopped working. I've tried different outlets but the microwave is not responding. Is there an internal fuse that has blown or is the microwave dead?


If the fuse is blown the microwave will be "dead". The fuse is accessed by removing the cover. You can usually find the fuse by following the power cord into the microwave. Unplug the microwave and don't touch anything except the fuse as the capacitor can hold an electrical charge.

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.

Fuse problem


I very much doubt it, chances are it has blown a capacitor or something along those lines, however the fuse in the mains plug should have blown before any damage was done, that's what they are there for, so if the fuse in plug is ok I think your microwave has had it.

If your microwave oven doesn't seem to work at all, check these: Fuses Door switch Fuses Usually, when your microwave oven doesn't work it all, the internal fuse (thermal fuse) is blown. This fuse protects both you and the oven. When it blows, you need to have a qualified appliance repair technician replace it. Door switch If the fuse isn't the problem, check the door hooks and the door-release button. When these are broken, the door switch doesn't activate, so the oven can't work

Unit dead Unit is dead - suspect blown fuse


Usually, when your microwave oven doesn't work it all, the internal fuse (thermal fuse) is blown. This fuse protects both you and the oven. When it blows, you need to have a qualified appliance repair technician replace it.

The reason for this is that if you do not have any experience and training with microwaves, you can get a SEVERE shock, even if the oven is unplugged. THAT being said, if you still want to know where the fuse is get back to me. good luck.

ALSO, as you may know, a small microwave these days is under fifty bucks at walmart.

Bosch microwave HME9750


the sighn with a spoon inside is to alert you to the dangers of delayed boiling this is were the liquid in a container is heated on the outside quicker than the inside when you remove the liquid and expose it to the ambient air in your kitchen the liquid can boil over scalding your hand it doesnt have anything to do with your friends cup of tea this is pure coincidence the pop is the internal safety fuse blowing will need attn from service tech to sort high voltage safety fuse blowing means inverter or mag faults.

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
