Sharp Insight Pro Microwave Not Heating Issues

Microwaves have become a staple part in most people’s kitchens these days. For convenience cooking and reheating of food there are few appliances that can measure up to the speed and heat accuracy that can be provided by a Sharp Insight Pro microwave.

Sharp Insight Pro microwaves are very reliable and can last for years and years before they need any form of repair. Nothing lasts forever though and over time you may find your Sharp Insight Pro Microwave having some performance issues over time.

In this article we are going to look at some of the potential problems that might cause your Sharp Insight Pro microwave to have issues with not heating correctly. We will also focus on how to troubleshoot and solve some of these situations.

Causes of Sharp Insight Pro microwave not heating.

The most common cause of a microwave not heating is that there is a fault with the power supply and as a result the microwave simply won’t function.

Another cause of the microwave not heating due to a lack of power can also be because of a blown fuse in the circuitry and not the power supply itself.

If it is not the power source or fuse, then there are some other possible areas of malfunction that may lead to the microwave not heating.

There is a key component to any microwave called the magnetron. This device is located deep in the inner compartment of the microwave and is responsible for creating the “microwaves” that create the heat effect. Any malfunction with the magnetron and that will almost certainly cause the microwave to stop heating.

Microwaves contain a diode that converts the A/C power into D.C. power, this is used to operate the magnetron. If the diode in your Sharp Insight Pro microwave is not functioning properly, neither will the magnetron.

Another cause for a microwave to not be heating could be the door mechanism of the microwave which may have a problem. The door being fully functional is imperative for the safe operation of a microwave, so a microwave won’t heat if the door is not completely closed or if there is an issue with the door switch. 

While a microwave is in use it needs to be ventilated properly to be most effective, which means a clogged or otherwise inhibited ventilation section of the microwave may be a cause for the microwave to not be heating correctly.

Some of these issues are not so easy to spot, and in some cases the microwave will appear to function as normal until you open the door to grab your food. Symptoms of such as your food being unevenly cooked through (nobody likes lukewarm soup!) or no temperature rise after a period of cooking are signs that your Sharp Insight Pro Microwave is not heating correctly.

Troubleshooting tips for Sharp Insight Pro microwave not heating.

Here we will introduce a few troubleshooting tips for some of the above-mentioned issues that may have caused heating problems for your microwave.

Firstly, we will focus on the power supply. Is the microwave correctly plugged into the power outlet?

If so, then maybe there is a problem with the outlet itself, check to see if it has any lights indicating that it is getting power or try another appliance in the outlet and see if it powers that. Failing that then check the fuse box and the microwave fuse as that might have blown which would cause a power shortage.

Now let’s have a look at any possible door problems. As we mentioned earlier the door must be closed properly during the cooking process for it to operate. The first thing to check then is that the door has “clicked” closed and shut, sometimes there can be something blocking the hinge.

There are some situations where the container of food is too big for the microwave compartment, which presses up against the door and just stops it from closing all the way.

Sharp Insight Pro microwaves have a push button that pops open the door automatically, this is something else that may break down over time and become non-functioning, hindering the microwave door from opening or closing fully.

There is also a seal around the microwave door that runs between the door and the microwave cabinet, this is something else that can become degraded over time or is susceptible to getting damaged.

The last things mentioned that may be a cause for a Sharp Insight Pro microwave not heating are problems with the diode and/or the magnetron. This is not something you can diagnose by yourself without a specific tool, that tool is called a “multimeter”.

A multimeter is a device that can measure various things such as voltage, current and resistance. They are around $40 so they do not cost too much and are useful to keep track of how well your microwave and any other appliances are performing.

If there is a problem with the magnetron, unfortunately it is a bit of a lost cause, it is so expensive to replace and not easy to do by yourself that it is not worth replacing it, you should at this point simply buy a new microwave. 

Repair and maintenance.

It is important to spend some time routinely maintaining your appliances to make sure that they are in fine working order, and your Sharp Insight Pro microwave should be no exception in order to avoid any issues with the microwave, such as it not heating your food.

Regularly check the ventilation area of the microwave to make sure that it is clear from debris and other blockages. Be sure to keep an eye on the door seal to see if it is starting to wear away with age or split in any sections.

Also ensure the outlet containing the microwave plug is not overloaded and that the fuses are up to scratch.

If you have no idea how to attempt to solve your Sharp Pro microwave with its not heating, or do not feel comfortable working with electrical appliances, then there should be many electrical trade stores or appliance repair experts in your local area that can be found online.
