Oven and microwave combo

It's probably the internal fuse.You will have to take the microwave down so you can remove the housing to get at the fuse.(I will probably install an accessable panel mounted fuse holder if this ever happens to mine-already did it on the little microwave I carry around on my work truck to heat up my lunch).

i believe you would have to take the entire microwave caseing off to access the back of the plug

1. Empty the Oven
   • Take everything out of the oven. Remove the racks and clean them with soap and water in the kitchen sink. Look for any loose debris such as foil or charred food and remove that as well.
     
   Oven Cleaning
   • To operate the self cleaning mode, find the switch on the range marked "Clean." The oven door will lock once the cleaning operation has started. Do not open the door until after the self-cleaning process has completed. It will take between two and three hours.
     During the cleaning process, you may see and smell smoke. This is normal because the oven is operating at a higher temperature than when it is cooking. The high temperature is reducing all the organic matter in your oven to ash. You will also sometimes hear popping sounds from the oven that is caused by the expansion of metal under extreme heat. This is normal for a self-cleaning operation.
     After the oven has completed the cleaning cycle, allow it to cool for a couple of hours. Once cool, take a damp dish cloth and remove the ash from the bottom of the oven. Wipe down the interior of the oven door and around the seal. Be careful around the seal so you do not damage it. Replace the racks back in your oven, and the cleaning operation is complete.
     
   Other Considerations
   • Clean your oven at least once every three months. If your oven gets heavy use, consider cleaning it once a month. Always run the self-cleaning cycle when you are home. Because it uses intense heat, it is best to perform this operation later in the evening or early in the morning.
     

Hi,
Here is a tip that will help you to figure out what is wrong with yourMicrowave Oven....

Microwave Oven Basic Troubleshooting Tips

When you say it's not working do you mean it is completely dead??? or it turns on but it don't heat??
When running an empty microwave it can damage the MAGNETRON because the inside coating of the microwave is design to bounce (reflect) the waves to whatever is sitting in the bottom/middle (food)... if nothing is there to ABSORB the waves, than it bounces back into the MAGNETRON and can damage it (if it runs long enough)... the magnetron is generally more expensive to replace than the oven it self... so to make sure if the magnetron is working, you could try a test with a HENE lamp (small orange neon bulb) in a glass of water, put the bulb in a full glass of water than put the glass in the oven, start the oven, if you see the bulb glowing orange (lights up) it means that the MAGNETRON is working, if not than you need a new oven...

Good luck!

Hello,

What this simply mean is that there has been a problem from the fan either from the wire connection or from the Cole of the fan connected to the fan motor.

There are two ways of over coming this type of problem below are the recommendation to solve the problem

First of all set the oven on self cleaning from the below instruction or make use of your owner manual to operate the elf cleaning
Please after the self cleaning you most allow the oven to cool down to it best before opening

Some ovens are self cleaning During the cleaning process, the oven heats up to a temperature of 900 degrees Fahrenheit. The extreme heat cooks off food and spills inside the oven, leaving ash that can easily be wiped out. The oven door locks while it is cleaning to prevent the door from being opened. Self cleaning ovens are better insulated than regular ovens to keep the extreme heat inside.

1. Read the owner's manual that came with your oven before you perform self cleaning. Although all self cleaning ovens work basically the same way, there may be slight variations for some manufacturers and models.
   
2. Take out the oven racks. You need to clean the oven racks by hand, and then put them back in when the oven is done cleaning.
   
3. Wipe up any spills and messes inside the oven first, using warm water and a mild soap. Ovens smoke more during cleaning when there is food inside. Wash the inside of the oven door as well. Do not scrub the door gaskets, just gently wipe them off. Damaging the gaskets prevents the oven from sealing.
   
4. Lock your oven door manually if your model does not lock it automatically when you clean.
   
5. Open a window near the oven for ventilation. There is a certain amount of smoke when you clean the oven. The dirtier the oven is, the more smoke is created.
   
6. Turn the control on your oven to "clean" and set the timer for 2 to 5 hours depending on how dirty your oven is, and what the manufacturer recommends.
   
7. Wait for the cleaning to finish and the oven to cool before opening door. When oven is fully cooled wipe up any ash inside. If your oven is not completely clean, next time set the timer for longer. If your oven is spotless you might want to see if you can get away with a shorter cleaning time.
   

SOLUTION 2 IF THE ABOVE RECOMMENDATION DID NOT SOLVE THE PROBLEM

Then you will have to replace the hole of the fan from the oven i.e the fan is need to be service

Hope this help?

Thank you and thank for using fixya.

check the safety switch for complete door closure.

The light inside the micro wave needs to be replaced most have a door on the back side that yo can remove the screw and unscrew the bulb and take to a applince shop and purchance a new one to replace.

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.
