The microwave needs to be on another circuit than where it is now. This happens with the 1000 watt models a lot. Either plug it into a new outlet that is on a new breaker or change the breaker to a higher amperage.

SOURCE: where is the power fuse

You can find links to helpful exploded view diagrams and part ordering help here.

I recommend that you bookmark that link to your favorites.

Running the oven empty will overheat the magnetron. It may just be a failed magnetron thermal cutout (also called a thermostat or TCO) or the magnetron itself may be destroyed.

Unable to adjust power level, the power level button on the control panel does not respond.


Try pressing and adjusting the power level before setting the cook time, or maybe before pressing start. Worked on my Panasonic

Whirlpool microwave fuse has blown multiple times


It depends on which fuse and when it blows. Wish you had mentioned that.

But usually it's a defective door switch or door switch mount.

If the fuse blows at random times while it's cooking, it may just be a loose fuse holder. Those have to be replaced due to metal fatigue, not just squeezed tight with pliers.

If it blows as soon as you hit "Start" to begin cooking, you have a shorting high voltage capacitor.

If it blows when you open or close the door, you have a loose or defective door switch or latch.

You can find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.

My microwave keeps blowing the fuse upon hitting the start button


you have one of three problems (H.V. diode shorted or leaky, H.V.capicitor shorted, or the magnrtron tube is beginning to draw excessive current)if thats the case its not usually worth spending that for the mag.,the other two items aren't that expensive

My mother just bought an Emerson MW8119 Microwave and can't figure out how to only set say 15 seconds cook time. Is it possible?


Hi! I just purchased the same microwave, and came online to find the solution. I was then able to find the correct answer to this problem. On this model, Emerson does not put a "time cook" button for odd cook times such as 15 seconds. Instead, they have you push the "Power Button" prior to setting the cook time.

If you want to cook on full power, press the power button once, and then enter your cooking time and press start. If you want to cook on 50% power or 30% power or something like that, push the "Power Button" several times until the appropriate power level is displayed, then enter the cook time and press start.

The reason that it starts up right away when *********** pushes the 1 button is because Emerson has the quick cooking feature for 1 minute through 6 minutes. You only have to push the number once to get the 1 minute cook time or anywhere through 6 minutes respectively.

Hope this helps!

Emerson microwave, #MW8119SB, push start button to start cooking


Replace the fuse with a ceramic fuse from Home depot! costs less than $3 and it will fix the problem. I had all the same problems as everyone else, you name it my microwave had it! you must remember replace it with a ceramic fuse! not a glass one. I know people say its the switchboard and all that nonsence but I promise you, the fuse plays a majoe roll in the microwave not working properly. Even though it doesnt look broken, a junky fuse can cause your appliance to do very strange things. I replaced mine 6 months ago and it works like its fresh out of the box.

Pushed cook button with nothing in oven now it doesn't work at al


Try to unplug your microwave then leave it for 1 hour the purpose is to reset and drain stored current after 1 hour plug it again ,if still notworking there something wrong inside. 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 replaced it or you need to have a qualified appliance repair technician replace it.

Hope it may help you;

Q - My microwave went dead when I opened the door ( same problem as closed the door ).
A - This often is a stuck or faulty door switch and it has blown the interior microwave fuse.
Q - My microwave is completely dead.
A - House fuse has blown or interior fuse inside the microwave has blown ( usually a part inside the microwave makes this fuse blow ) Sometimes a bad fuse holder inside the microwave cannot hold the fuse tight enough and the fuse will blow as well. 
Q - My microwave blows the fuse inside itself as soon as I push the start button.
A - Usually a shorted high voltage capacitor...see components section.
Q - I burnt something in my microwave and now it is dead...help!
A - The fuse inside the microwave may have blown, but more commonly the flame/oven thermostat has sensed the over cooked food and the flame/oven/cavity thermostat has opened up - Info on that 
Q - My microwave seems to shut off every once in a while, what might be wrong?
A - Make sure you hear the fan is still operating in your microwave. Next is to make sure the air intake grill on your microwave is not plugged up with air borne dust and dirt.
Q - The microwave makes a loud "hum or buzz" noise but will not heat up the food?
A - 9 times out of 10 this is usually this is a bad magnetron, the other time is sometimes a bad high voltage diode. See components section.

My Touch pad does not work, can someone help? kenmore mocrowave model 721.62624200 microwave buttons work sporatically. if i push in a downward motion they work sometimes microwave blew a fuse a couple of...


It sounds like the keypad is worn out. The fact that you can get them to work sometimes by what direction you push on them, tells me that the contacts are not working correctly.

Did you have this problem prior to the fuse blowing or did it start after you replaced the fuse?

I don't believe the fuse blowing is related to the keypad problem. I also don't believe that you have a microprocessor problem because you say that the function buttons work but the number keys don't work right. If the microprocessor was faulty, it would not be able to read any of the keys.

The fact that the number keys are not working doesn't surprise me. When you go to cook something, you will press the number keys several times, while only pressing start or stop once. This is why your number keys have worn out first. These keys have a limited number of cycles (presses) and it sounds like its time for a new keypad.

Please let me know if I can be of further assistance to you.

Good Luck!

Sunbeam SMW5500 micro/convection oven shorted out when opening door


You are decribing a typical Door Safety Switch problem. The Door Safety Switches has Failed.The Door Safety Switch is designed to shut down the Micro in the event the Micro is still cooking when the door is being opened. The first "Click" of the switch cuts off the "Cook". If it does not cut off the "Cook", the second "Click" blows the power. Otherwise it would "Cook" with the door open, and I need not to tell you how DANGEROUS that could be. It first Tripped the Circuit Breaker which supplies power to the Microwave. After Re-Setting the Breaker the same thing happened except this time the Micro is DEAD- not even a light working. Yes, there is a line FUSE inside the Micro. You however need to address the Door Switch SHORT before replacing the fuse. If not, it will just Blow The Fuse Again, and Again, until the Short is corrected.
Call around, ask How much to replace a Door Safety Switch.
Good Luck!

It is possible that the magnatron is bad but hard to say on a no heat problem without checking all components. A lot of model give 5-7 yr warranty on that part.
