How To Fix A Microwave Oven?

You would probably be right to say that the microwave is one of the best inventions for people who are busy. The microwave allows us to cook food at least 90% faster than the regular oven. Millions of people worldwide have benefited from the microwave’s fast food. Though, the amount of radiation we may be exposed to on a daily basis, becomes a concern for some people.

How Does The Microwave Work?

Microwaves are designed to heat food by utilizing waves that makes the water molecules in food vibrate rapidly. This molecule vibration produces energy that comes off as heat to cook the item. The designers and manufactures of the microwave built it to contain the waves when the door is closed when it is turned on, releasing microwaves and heating food.

Through time microwave ovens have never failed to satisfy the constant needs of a average household. But just like everything else that’s man-made, eventually there comes a time when there is might be a problem with your microwave oven. It can be very difficult to identify the exact problem is, if you have no idea on what the symptoms of the problem might be. Therefore, after purchasing your microwave, you should get educated on the potential repairs that may have to be done in the future.

Only in its worst condition should microwave oven repair be done. Because the microwave is not like the average oven radiated by heat, all directions and precautions should be based on the product manual. Microwaves come in a lot of different brands and they have general guidelines to abide by. A lot of times the proper education along with common sense can save you from a major costly repair. Get to learn and know the symptoms of a microwave that needs repairing through observing its behavior patterns.

What if my microwave is not functioning at all?

The first thing you would want to do in this situation would be to plug the power cord into the outlet properly. After that is done, you may want to check for loose connections. Remember the door must be closed properly or the microwave will not cut on or run. Microwaves come equipped with an auto detect function or cut off switch to avoid radiation leakage. Another thing you should do if the microwave is not coming on is check the fuse and replace it if needed.

What if you see sparks coming from inside the microwave?

Be sure to always remember to remove all aluminum items before the use of the microwave. Aluminum items such as foil, forks, spoons, knives, and items with metallic trims are famous for causing sparks within the microwave. Examine your microwave carefully, and check for microwave paint that may have chipped off. If this is the case, then I would recommend that you repaint the microwave with some anti-heat resistant epoxy or a recommended paint substitute. Before you attempt to paint anything, make sure that all the burned residues are scraped.

Why is the microwave’s turntable not turning?

If for some reason that turntable stops turning, you will notice that your food doesn’t get heated evenly and thoroughly or it gets over heated in one spot. To try to troubleshoot this problem, make sure that the rollers and tracks are properly aligned and assembled correctly in its location. Check to see if you are using the correct glass plate, according to the manufacture’s product manual guide. Check to see if you have something over-sized in the microwave preventing the proper rotation. Or it could be a broken internal mechanism that needs repairing.

The microwave comes on, but does not produce heat to warm the food. What is wrong?

If your microwave comes on, but there is no heat being generated then the first thing you should do is wipe the walls of the microwave with some mild detergent, and water for clear releasing of waves. After that task is done, then you should listen carefully and observe the sounds and the certain buzzing sound of the magnetron, which is basically the main microwave generator. If a crucial part like the magnetron is damaged, then it will require some professional repairs.

    1. Kamaroon, it’s quite common for a microwave to get warm on the outside after heating food, especially in older models. Microwaves are not always that well-insulated so the heat from the inside while cooking can seep to the outside. It’s usually not dangerous. Just make sure any vents are unblocked and that you don’t have the space around the microwave too cluttered.

    1. Gail, you didn’t mention what type or model of microwave you have, so I can’t give any specific advice to you. However, I did a brief online search for you and it seems the most common response from various DIY microwave repair guides suggest that the microwave not be used until it can be checked out by a professional repairman. In other guides, the advice is to get a new microwave because it can’t be repaired. The consensus is that if the burn hole is bigger than the holes in the mesh screen, then the microwave can’t be repaired, and that it is very dangerous to use the microwave if the holes are that big.
