This article is all about the causes and solutions of Panasonic microwave overheating.
Overheating and burning smell of ovens has almost the same reasons.
First, we will understand the working principle of electrical appliances to explain better the issues and problems behind overheating.
In microwave ovens, food is heated using microwaves, electromagnetic radiation similar to radio waves.
Microwaves may be used for cooking because of three characteristics: they are reflected by metal; they pass through the glass, paper, plastic, and other similar materials ; and meals absorb them.
A magnetron inside the oven produces microwaves.
Because of the microwaves’ reflection off the metal within the oven, food and water molecules vibrate.
As a result of the molecules rubbing against one another due to the vibration, heat is produced, which cooks the food.
Panasonic Microwave overheating has numerous problems on its back and have discussed below in detail.
It is worth mentioning that ovens’ burning and overheating are interrelated, and reasons are clearly written.
Overheating of Panasonic microwave involves loose wiring connections, overcooking of food, issues in the magnetron, high voltage diode, and other electrical accessories.
The primary and most common cause is “insulation around the oven chamber producing smells due to overheating the first few times it is exposed to the intense heat inside the oven.
Let’s dive into detail.
Why is My New Panasonic Microwave Overheating?
The new ovens are where overheating problem is most prevalent.
There is a chemical odor because the insulation around the oven chamber is being exposed to intense heat for the first time.
You need to “burn in” your oven to solve this issue.
It’s possible to smell or see smoke during the first few usages; the manufacturing process causes this.
This is expected and will pass.
We can probably all agree that this is a fairly typical problem with brand-new kitchen appliances; however, it is also important that the zip-ties used to secure the inserts during shipping must be removed before using the oven.
If not, these zip ties will begin to burn when heated, which may also emit an odor like that of the chemical coating.
However, this burning fragrance due to overheating need not just be associated with recently installed ovens; it may also be noticed while cooking in an ancient oven.
Although it may seem to happen “all of a sudden,” there is a reason behind it.
Causes for Panasonic Microwave Overheating
Following are the main technical causes of a burning smell and overheating.
Overheating due to Overcooking
Your Panasonic microwave oven overheated because of overcooking food when you didn’t care about the precise cooking time.
The temperature sensor and the major parts of the control board will be damaged.
The main board and several sensors, including humidity and temperature, do, however, have a little gap.
All of the sensors are wired together and might burn out from overheating.
No moisture in the food to heat
It is possible for a microwave to overheat if there is no moisture in a food to heat.
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 the microwave comes with automatic shutdown feature if they do, though.
It’s very not likely that your microwave will overheat, but if you are cooking something for a long time, there’s a chance it will overheat.
Faulty fan
Another reason for microwave to overheat is because of a faulty fan.
Microwave fan regulate the temperature of the microwave.
You can check the microwave fan easily whether it is working or not.
You can hear the sound of fan whenever the microwave is cooking.
So, you should be able to tell almost straight away if there is something wrong with the microwave fan.
Without the fan to regulate the temperature, the microwave will overheat fast and shutdown.
Issue in Magnetron
The magnetron tube is a crucial part of the microwave oven.
Food is cooked more quickly by creating heat.
The microwaves that produce the heat are powered by this component, which is a part of the high voltage circuit.
If the magnetron is destroyed, the device may blow a fuse, or the other features may continue to work as intended.
If your microwave is facing overheating issue similar to the one described at the start, it may be caused by a high voltage capacitor issue with the main circuit board and magnetron tube.
High Voltage Diode Problem
High voltage diode and high voltage capacitors are the essential components of microwave ovens.
Overheating of microwave may be due to this diode problem and can cause severe problems for you.
Please check your diode with the help of advanced digital instruments to avoid the overheating problem at the early stage of problem rectification.
Loose Wiring and Connection Problem
This is the most common problem you faced in numerous issues related to Panasonic microwave ovens.
This problem might damage your oven, cause overheating, and is responsible for the burning smell.
Check the connections and wiring carefully, and you may follow the solution section below to rectify the problem.
Solution of Panasonic Microwave Overheating
We are sure that our solution guide will help you to avoid overheating the microwave oven. Please go through the following subheads as a generic solution to all the problems related to overheating of Panasonic microwave.
Avoid Overcooking
Overcooking meal in the oven is the core and common problem of overheating.
You can solve this problem by simply taking care of your cooking time.
Follow recommended time for cooking; otherwise, you may face severe consequences.
Check Sensors and Magnetron
Sensors, actuators, and magnetrons are the essential items or components of the microwave.
Voltage fluctuations, rough use, and many other problems may be faced due to the failure of these devices and can be responsible for the burning and overheating.
Tightening of loose connections (if any)
A licensed professional electrician is needed to inspect, tighten, and repair electrical components along with wire connections.
Major electrical components must be tested for continuity using a digital multimeter.
If you or your electrician discovered damaged components, get them from Amazon so that a specialist or professional can quickly replace them.
Small electrical sensors and wirings often burn due to strong voltage disturbances.
We hope this solution will enable you to address the issue at its early stage of fixing and eradicating it.
Replace faulty fan
Microwave fan helps to regulate the temperature of the microwave.
So, there is direct link between the microwave fan and its temperature.
If the fan gets faulty, your will microwave overheats.
So, if the fan is faulty, you need to replace your Panasonic microwave fan.
Proper Cleaning and Avoid Extensive Use
Cleaning microwave ovens regularly may be necessary to prevent the blockage of the cavity sidewalls, which is the cause of burning.
The temperature will naturally increase owing to an increase in internal heat if the sidewalls of your cavity are obstructed by food and dust particles.
Some delicate electrical components burn, a stench may be detected, and burning will occur when internal heat or temperature rises.

Final Thoughts
Overheating of Panasonic microwave involves loose wiring connections, overcooking of food, issues in the magnetron, high voltage diode, and other electrical accessories.
Overheating and Burning smells have some causes and are associated with each other.
Extensive care is needed to handle the overheating due to the overcooking in the Panasonic microwave.
Regular cleaning of microwave is also equally important to limit the blockage of sidewall cavities.
However, technical measure plays a crucial role in rectifying the overheating problem and covers checking various electrical sensors along with replacement.
