Microwave is sparking (reasons)

Microwave is sparking (reasons)

Sparking in the microwave is a common thing. Liquid spilled inside the appliance of a microwave or grease accumulating on the interior sides of your microwave is believed to cause sparking in the internal cavity. This occurs when you subsequently cook with your microwave in the same condition. When microwave energy accumulates in one area of your oven due to a faulty fan motor, high voltage diode could develop problem causing microwave sparking.

When microwaves were introduced to people, several amateur experiments were done to see how different foods reacted to this new technological method of cooking. The tests showed that microwave could cook all types of food when instructions are well followed. They also revealed that careless handling of the microwave could cause sparking and hence can void your device.

Cleaning microwave to avoid sparking

Microwave ovens should be cleaned after every use to avoid build-up of food residue which causes sparks. Most microwaves are fitted with glass turntables that can be easily removed, soapy water cleaned, dried and replaced. Microwaves have an internal cavity which should be cleaned with a moistened cloth. This ensures that your microwave is in good condition which is recommended by manufacturers. It is advisable that you should cover your microwave with waxed paper or with a microwavable plastic cover before cooking to reduce spills and splatters that are known to cause sparks.

Reasons of sparking in a microwave

Sparking inside a microwave is common and does not show your microwave has a problem. Most people panic when their microwave sparks. When your microwave sparks you are required to switch off your microwave and do necessary inspections. Below are possible reasons for sparking of your microwave:

  • Scarp of metal inside microwave

A small piece of metal is enough to cause sparking inside your microwave. This mostly occurs when you clean your microwave with steel wool and leave behind a metal scrap from the wool. Also, the food you heat may be covered with foil that catches fire easily. If your dish is not microwave safe, sparking may occur. Making sure that there is no metal scrap in your heating dish makes it microwave safe and its safe for you to start heating with your microwave.

  • Having a damaged waveguide cover

Waveguide cover is found over the magnetron and is used to guide or convey the heat waves to the central area where you keep food in a microwave. The cover also prevents food particles from entering the magnetron which may be dangerous. It is believed that during cooking food particles and grease escape and stick to the waveguide. The food particles are burned by heat from the magnetron and sparks out. These sparks damage the waveguide cover making it cause frequent sparks from the microwave. This can be solved by replacing damaged waveguide cover with a new one and taking great care to avoid its damage.

  • Having damaged rack support

Rack support is a hook-like instrument that is used to support microwave. Most of the time microwave sparks near this support tool making its paint to worn out. It is advisable that you remove the support and immediately replace it with a new one to avoid future unpredicted sparks.

  • Burned diode

Microwaves have high voltage diode which causes sparks inside microwaves when burned or shorted. This can be prevented by ensuring that you use correct switches and recommended sources of power when cooking with a microwave.

Next time you see sparks inside your microwave never get scared instead switch it off and perform a necessary inspection before calling your technician.

Burn spots

Burn spots inside your microwave are clear indication that sparking has occurred and ignoring them may cause a damaging fire inside the appliance. Calling a technician is the best option since he can locate the situation and discover the immediate reasons for burning. If there is any damaged part requiring replacement, the technician will locate what is needed and perform the recommended replacement service. It’s advisable always to call a technician if you are not familiar with all the components of microwave oven because it can give you a severe electrical shock.

How to repair a sparking microwave

If you see sparks while running your microwave, it’s advisable first to check its internal cavity of your device. If you notice any splattered food into the microwave, you should continue to cook but be read to notice some sparks inside. This can also apply when grease accumulates on the ceiling of your microwave oven. We recommend that you stop cooking and thoroughly clean the internal cavity of the microwave oven.

Inside a microwave, there is a stirrer which ensures even heating inside your microwave as well as ensuring even distribution of energy created by the appliance. If the stirrer is not working well, the created energy will concentrate in one area instead of being distributed to all areas in a microwave, and this is believed to cause sparking or burning. The reasons why the stirrer may fail to work is when the stirrer belt is broken or when the drive motor is broken. Replacing these faults will prevent sparking hence ensuring safe heating.

Inside a microwave, there is a diode which works together with the capacitor and the magneton to provide the heat needed by microwave to work well. When attempting to access the diode, it’s advisable for you to unplug the microwave as well as discharging the high voltage capacitor to avoid getting an electrical shock. After removing the diode, you can test it for continuity using multi-meter and if there is low resistance in one direction and high resistance in the other direction the diode is correctly working. If you do not notice any resistance the diode, it’s not working and should be immediately replaced by a technician to avoid sparks.


Are Microwave Ovens Safe?

Are Microwave Ovens Safe?

The microwave has been around for a very long time now. In fact, it has become a staple in kitchens all over the globe. More importantly, it has evolved over time, from an appliance that simply warmed up already prepared dishes to an advanced appliance that cooks entire meals. Whatever the case or situation, microwaves are commonplace in homes and businesses all over the U.S. and abroad.

Even though the microwave has been around and appears to be here to stay, there are still a number of different questions that many people have on their mind. One of the more notable is, are microwave oven safe. Since these appliances are operated by using radio waves and infrared radiation, it is not uncommon for people to become a little apprehensive or afraid of these factors. Therefore, when people actually understand how these appliances work, they are much more likely to become hesitant about the safety of their use. For instance, whenever an individual visits their doctor or a hospital for a test that requires the use of radiation, they are asked several different questions in advance. Many of which are related to how safe the person will be around radiation and what precautions should be taken.

In some cases, an individual cannot be exposed to any type of radiation. Particularly, in situations where a mom is pregnant or think that there is a possibility that they are with child. Additionally, if the person is not having a Xray done with the use of radiation, it is important that they follow directions as they are given. These instructions are usually provided for each individual so that they are not adversely impacted by the radio wave technology in their body. For instance, extra visitors in the Xray room are normally asked to step out while the X-rays are being taken. Once these tests are complete, they are free to come back in. In fact, one of the primary reasons for asking others to step out of the room is to eliminate exposure to radiation.

With that said, it is also important to know how microwaves work. In specific, how do these appliances work as they are compared to adversely affecting the user and other family member’s overall health? So, what is the answer to the question, are microwave ovens safe?

The answer to this question will vary since it is often dependent upon the circumstances that is being encountered. So, people will need to do their homework first prior to handling a microwave oven. Typically, when an individual in the home or a business office uses these appliances properly, the answer is yes. This is the proper use helps to reduce the potentially harmful effects of the microwave. Also, in order to make sure that there are no unnecessary problems, the user will need to read the manufacturer’s manual very carefully. Meaning these appliances are safe for both heating and cooking various kinds of foods in the time frames allotted when they adhere to the guidelines and rules of working with this kind of product. On the other hand, when the user is taking the proper precautions, they will not be pre-disposed or unnecessarily exposed to thermal burns.


Follow International Standards

In addition to making sure everyone in a specific area knows how to handle a microwave safely, it is also important that they know what the international standard is for their overall design and functionality. So, it is essential that consumers are familiar with these standards in order to apply them appropriately. For instance, if a microwave has sustained a certain amount of damage, it may be prone to leakage around and through its doors. To prevent these and other situations from occurring, these appliances must be maintained properly so that they will remain in good condition at all times.


Food Safety

Another issue of concern is food safety. Food safety can be a health risk that can pose problems too. However, before the safety of the food is unduly compromised, everyone will need to know what issues and risks are involved in its preparation. One of which involves the food being heated unevenly and dangerous micro-organisms remaining in the food. With this in mind, the users of these appliances will need to make sure that they know how each type of food should be prepared and how long it should take before the food can be served.


Are Microwave Ovens safe? The answer to this question will vary based on the situation. In particular, if the individual uses this appliance according to the manufacturer guidelines, there should be no unnecessary problems. Or, when the food is prepared using the safest temperatures, the heat will kill out all the bacteria. So, it is important that people are familiar with its use to ensure the microwave remains safe.

How To Make A Mug Cake In A Microwave Oven

How To Make A Mug Cake In A Microwave Oven

Mug cakes are the perfect gastronomical fit in today’s instant society- quick to make, delicious and makes use of only a few ingredients and a microwave oven.If you’re in the mood for cake but all the shops are closed, a cake in the mug could be the next best thing. Here’s how to make mug cake that you’ll surely love.

What You Need

A microwave oven

All purpose flour

Granulated sugar

Baking powder



Mug cakes come in a variety of recipes, each with their own unique ingredients. The ones listed above are the most basic. The good thing about mug cakes is that you can make your own version once you get the hang of making one in the microwave oven. You can make a basic mug cake out of vanilla, chocolate, red velvet, lemon or go all out and make your version of birthday mug cake or sticky toffee mug cake. It depends on what you have on hand and your personal preference.

Here are the general steps for the base batter:

Step 1. Take one large mug that’s microwave safe and spray the inside with cooking oil or butter. The mug should be large enough to hold 16 oz, or otherwise the batter will spill out and the cake will be ruined.

Step 2. Put in the dry ingredients- flour, baking powder, sugar and any ingredient for your specific mug cake. You can add in a pinch of salt if you want the cake to taste less sweet. Stir them all together using a fork.

Step 3. Mix the wet ingredients next. Pour the milk in your large mug. Add vegetable oil, vanilla/chocolate or the flavored extract, then stir them all up using a spoon. Scrape the bottom and the sides often as you mix.

Step 4. Add the sprinkles if you’re making a birthday cake.

Step 5. Put the large mug in the microwave. Set the timer for 90 seconds on full power.

Step 6. Put the mug cake out of the oven and allow at least 2 minutes before eating. Serve with ice cream or whipped cream. Add jam or nuts before digging in.

Tips To Ensure Mug Cake Success

Add Air To Make Your Mug Cake Rise. Batter rises because of baking powder, but be careful not to add too much as it could rise and fall quickly, turning the cake into a dense mixture. Mix the wet ingredients well and fluff it up just to be sure.

Don’t Stuff The Mug. Just because you have a large mug doesn’t mean you should overfill it. Put in too much and the extra ingredients will just splatter on the microwave. If you’re looking for more than just a single serving, transfer the contents and double it into a microwave-safe bowl.

Eat Immediately. The unspoken rule of mug cakes is that they should be eaten immediately after cooling. Steamed cake batter is best consumed right after they’ve considerably cooled down. If you leave your mug cake after 10 minutes, the gooey texture hardens and it becomes more like a chocolate bar.
