Microwave ovens last for a long time and you can expect to get around 10 years of use out of them before you consider getting a new one. When you get to that point, there may be some issues with your oven as a result of old age.
In this article, we’ll be looking at some of the most common problems you will face with a microwave oven and how to remedy them. Bear in mind that microwave ovens are a relatively inexpensive cooking appliance and if your microwave oven is faulty, it may be cheaper, quicker and easier to just replace it with a new one. If that’s the case, shop from our range of microwave ovens, including our combination microwaves and microwave grills for a great deal, with options to suit any budget and free shipping.
Faults, Fixes and Help with Microwave Oven Issues
Why is my microwave not heating up?
There are likely to be three possible reasons why your microwave oven isn’t heating up:
Can you overheat a microwave?
It is possible for a microwave to overheat. The microwaves heat food by targeting water molecules, if there is no moisture in the food to heat, this can cause overheating. The vast majority of them have an automatic shutdown feature if they do, though. It’s very unlikely that your microwave will overheat, but if you are cooking something for a long time, there’s a chance it will.
Another reason it may overheat is because of a faulty fan. You can hear the fan whenever the microwave is cooking, so you should be able to tell almost straight away if there is something wrong with it. Without the fan to regulate the temperature, the microwave will overheat quickly and shutdown.
Why is my microwave sparking?
If your microwave is sparking, do not panic. Just switch it off at the wall, and then inspect it. There are three main things to look out for if your microwave is sparking:
If none of these explain why your microwave is sparking, you should consider calling a technician or replacing the unit.
What do you do if your microwave catches on fire?
If your microwave oven catches on fire, you need to act quickly and calmly. If it is safe to do so, turn off the microwave oven and unplug it immediately. If there is a fire burning inside the unit, do not open the door to try and extinguish it. This simply opens up the possibility of the fire spreading elsewhere. Wait for the fire to suffocate inside the oven before you think about opening the door.
Don’t take your chances, either. Alert the authorities if there is any risk of the fire spreading. You can prevent this ever occurring by:
Why does my food spark in the microwave?
It is possible for your food to cause sparks in your microwave oven, this is most commonly seen in dense vegetables. Their higher content of minerals can cause sparks to fly. Your food may display small signs of burning but should overall avoid damage and still be safe to eat.
It is most commonly seen with carrots, spinach, bell peppers, green beans and other dense vegetables. The sparking is a result of microwaves reflecting off of the minerals found within the food. It’s still safe to eat, but the sparking may cause your food to not be as heated as you may have hoped.
Why do my microwave buttons not work?
There are three potential areas of the microwave that would explain the controls of it not working:
- The control panel
- The membrane switch
- The control board
If some of the buttons on your control panel work and others don’t, then the problem most likely lies with the control panel itself and it will most likely need replacing.
If this doesn’t explain it, it could be the membrane switch. It has a conductive layer around it which can become faulty after a while of usage. To check for this issue, you will need to ensure it is unplugged and remove the cabinet of the microwave. Using a multimeter, check the membrane switch. It should give you some ohms of resistance. If not, it needs replacing.
If the touch controls of your microwave are unresponsive but the display lights are still working as usual, it is most likely the problem is with the control board. The control board provides power for the membrane switch. Without it, your oven buttons won’t work. This is a complicated component to replace and is best left to outside help.
We must reiterate that unless you are confident you know what you are doing, you should seek professional help when conducting repair work on your microwave oven. Even if you unplug the unit, thousands of volts can be stored inside and cause a seriously harmful shock if you don’t know what you’re doing. Avoid tinkering with the electrical components of the unit at all costs.

Why does my microwave plate not spin?
This is another problem that has a few different possible explanations;
Hopefully this has addressed any problems you may be having with your microwave oven. They generally run very well and you’re not likely to run into many problems with your microwave. You can expect your microwave to show these signs of wear and tear after around 10 years of use. If there is a problem with the electrical components of the unit, leave it to a professional unless you’re absolutely confident you know what you’re doing.
