How long do LG microwaves last?

On average, LG microwaves have a lifespan of about 7 years. In some cases, if they are kept clean and well-maintained, you could own an LG microwave for up to 10 years!

To maximize the life of an LG microwave, it is recommended to clean and clear out dust and debris from its vents every six months to prevent grease and moisture from affecting its performance.

When the time comes to replace an LG microwave, it is important to carefully measure the space available and choose a model that fits perfectly without any gaps or other issues.

It is also important to look for energy-saving models with features such as sensor cooking that can help reduce energy bills over time.

What to consider when buying a new long-lasting LG microwave?

Warranty and service calls

When purchasing a new LG microwave, customers should keep the make and model number, warranty information, and purchase receipt on hand for any service calls that may arise.

Additionally, customers can look for support options by visiting the manufacturer’s website or phoning them directly regarding any warranty information.

Finally, it is important to keep track of the serial number of your microwave in case any service issues occur in order to easily reference it if needed.

Design and features

When it comes to design and features, your LG microwave is not only built with the most efficient design but it also carries along with it many different options you can choose from.

Directions and menu for your convenience and also available to prevent you from mistakenly using your microwave improperly.

Quick settings for defrosting and timers are available as basic features to help prevent mistakes when using yet how to microwave

Power settings and wattage

When shopping for a new LG microwave, consumers should consider power settings and wattage.

Many experts recommend an average of 1,000 watts for homes. Higher wattages come with higher price tags but can provide faster cooking times.

Knowing the wattage of a microwave will help determine how long it will last and ensure that it provides optimal results when in use.

Repair costs

When considering the cost of repairing an LG microwave, it is important to note that the most expensive part to replace is typically the magnetron.

On average, repairing an LG microwave can cost around $150. However, due to the complexity and the labor involved in replacement, it may not always be worth investing in repairs for this appliance.

Therefore, before deciding whether or not a repair should be made to an LG microwave, one should ask themselves if it can be done in a straightforward manner.

Maintenance and cleaning

When using a new LG microwave, it is important to keep in mind some maintenance and cleaning tips.

To increase the lifespan of the appliance, it is important to wipe down the exterior and interior after every use.

Monthly deep cleanings should also be done to help maintain the performance of the microwave.

Additionally, checking for any defects in power cords can help avoid future issues with your LG microwave.

Finally, having your appliance located in a well-ventilated area can prevent foodborne illness caused by bacteria buildup over time.

With regular maintenance and cleaning, an LG microwave can last many years before needing replacement or repair.

Quality and performance

Quality and performance have always been major factors when it comes to the longevity of your LG microwave.

The way it’s built and the way it handles cooking are very important factors because powerful microwaves usually last longer than weaker ones.

If you want to customize your microwave, you can choose from options that are both cheap and expensive.

Lastly, knowing how long an LG microwave usually lasts can help you choose a new model in an informed way.

Model reputation and reviews

We’ve all heard of brand reputation, but have you ever heard of model reputation?

It is important to consider the model’s reputation and reviews when buying a new microwave in order to ensure that the product meets your expectations.

Certain types of line units that come out on the conveyor belt from a company like this are built with the best materials. So when it comes to different models, it does make a difference.

Customer reviews can give you an idea of how reliable and long-lasting the microwave is, as well as any issues or problems that might come up when it is used often.

Installation and setup

To properly install a new LG microwave, one can either do it themselves or have it professionally installed.

If the microwave is an over-the-range model, then professional installation is required.

To ensure a successful setup, one should first determine the best location for the appliance and double-check that all power connections are in place before turning on the device.

Once it is plugged in and powered up, you should be good to go and ready to cook your first meal.

Door seals and interlocking mechanism

To ensure that your new microwave functions properly and lasts a long time, check for signs of wear and tear such as worn door seals or worn roller guides that may need replacing.

Noise level and sound

Noise level and sound are important considerations when purchasing a long-lasting LG microwave.

If the appliance is making loud noises, it may be an indication that it is time to replace the microwave. It should make no more than a low hum in the background.

What are the most common problems with LG microwaves?

The most common issues that are present with LG microwaves are:

  • Displays that are not working properly
  • Confusing Codes that are hard to figure out
  • And loud machines that are louder than a normal operating machine should be.

With the display, this could be any number of problems, from a bad fuse to a destroyed motherboard that is not working at all anymore. This can make it very hard, if not impossible, to keep using the microwave as you normally would.

With the confusing codes, the LG microwave is going to throw a code or display a code every time something out of the normal realm of operation occurs.

This means that you do need to keep your owner’s manual handy so that you can check those codes and see what the issue is. You can also request that a repair technician come out and determine what the code is and what needs to be done to repair it and get it working again.

For machines that are loud and that are working very noisily, this could be an issue with the motor, the magnetron, or any number of other issues that might be causing trouble.

What’s the first thing that goes bad in an LG microwave?

As with any microwave, the control panel is the first thing that is likely to go bad with an LG microwave.

The reason for this is that these buttons are being pressed every single time the machine is used. This means that they are more likely to wear out than other parts of the machine that are designed to last a bit longer.

The magnetron on the microwave is likely going to be the last thing to go bad in your microwave.

Factors that affect the lifespan of your LG microwave

Build quality

The build quality of a microwave is one of the most important factors when it comes to its lifespan.

Good build quality means that the microwave is made of good materials that are durable, don’t break easily, and are less likely to cause fires.

Poor build quality means that the microwave is made with flimsy materials that can break easily and often catch fire.

Small issues, such as dirt and grime buildup, are frequently easily solved with a simple cleaning or minor part replacement.

However, more complex issues, such as roller guide wobble, may require more extensive repairs in order to ensure long-term reliability.

If you take good care of your LG microwave and have it serviced regularly, it will last a lot longer than if you don’t.

Frequency of use

The more you use your microwave, the more likely it is to break. As a general rule of thumb, if you use it often, it will need to be replaced sooner. If you use it less often, it will last longer.

The average life expectancy for microwaves with regular use is around 7 years, while those that are used less frequently can last up to 10 years.

To make sure that your LG microwave lasts as long as possible, you should follow the maintenance schedule and take care of it regularly.

Maintenance and repairs

Dirt and dust can collect on the outside of your microwave. To keep it clean, use a soft cloth dipped in warm water and dish soap, then wipe the surface with it.

Before you use your appliance, clean off any food or dirt from around the buttons and look for any damage that could happen during normal use.

Keep food remnants out of vents so they don’t clog or cause other issues in your appliance. Remove them as soon as possible if you find them.

You should also clean the filters in your over-the-range microwaves regularly—every six months if they’re clogged—to make sure there’s enough airflow through the fan system of your microwave, which keeps it from getting too hot.

Type of food cooked

The type of food cooked in an LG microwave can have a direct impact on its lifespan.

Certain foods, such as those that require high temperatures or long cook times, may cause the microwave to wear out faster or even overheat.

If it’s a vegetable or fruit, it’ll dry out in the microwave because water evaporates from these foods as they cook.

The problem here is that if too much water ends up evaporating, then those water particles may find themselves getting into the electrical components of your microwaves and causing problems down the line.

Meat and fish are usually lower in water content, so they tend to steam less. This is because microwaves cook food from the inside out—the flesh beneath the surface is often cooked first, then progressively works its way toward the center and surface as time passes.

Power requirement

Additionally, the wattage of an LG microwave can impact its lifespan.

Microwaves with wattages of 1,000 or more are generally designed and built with higher efficiency and higher-quality parts, and they are likely to last longer than lower-wattage models.

However, if the wattage is too high, your microwave may overheat and not last as long.

Sensor reheat settings

Since the sensor reheat settings are designed to prevent food from overcooking, you can use them to reheat the food without drying it out.

The sensor reheat control is a setting that tries to calculate the amount of moisture in your food so that it can take the appropriate actions for heat and cooking time.

This is a great option if you want your food to be warm and delicious but don’t have time to figure out how much time and power are required.

You should also know that some foods will take longer than others when using this setting, so make sure you’re paying attention when adding items like bread or pastries into the microwave.

If your food doesn’t seem warm enough after pressing “reheat,” give it another few minutes before checking again.

The design of the interior

For many people, the design of their microwave is an important factor in deciding which one to buy. The interior design can determine how well your microwave works and how long it lasts.

The most important thing to look for when considering a microwave’s interior design is efficiency.

This means that the microwave uses as little electricity as possible while still providing you with high-quality results.

A good way to tell if your prospective appliance has good efficiency is by looking at its energy rating: anything over 10 will do just fine (though anything under 8 may not work well).

Size of unit

Size matters.

It’s important to consider how much space you have in your kitchen before deciding which microwave is right for you.

If you don’t have much room, a smaller model might be better than one with a lot of features or storage space.

There’s no point in buying something too big if it won’t fit into the area where it needs to go!

Delivery and installation

You will want to make sure that the delivery and installation of your LG microwave, as well as any necessary repairs, are done by a trained professional. and done properly.

In general, delivery and installation should be done quickly, and as little as possible should be done to bother customers.

It’s also important that these two tasks are done quickly and don’t hurt other things in the kitchen or on your property.

User interface and control panel

How easy it is to use and control an LG microwave can have a big effect on how long it lasts.

If the user interface or control panel is malfunctioning, it might be causing heating or turntable issues that could shorten the life of the appliance.

To help ensure that your LG microwave lasts as long as possible, it’s important to make sure all components are in good working order by regularly checking for signs of wear and tear.

Also, be gentle with your microwave. Avoid pressing the buttons too hard and banging on the machine whenever you’re frustrated.

Additionally, proper maintenance of your LG microwave will help extend its life and prevent costly repairs in the future.


LG microwaves come with a one-year warranty that covers damage from water, accidents, and other hardware or appliance problems.

Consumers are advised to refer to the instruction manual or contact the manufacturer if there’s something wrong with their less-than-1-year-old LG microwave.

If it is an older model, it may be time to replace it or have it repaired. Unfortunately, that might cost you money out of pocket. Online guides and communities can also provide additional support with this process.

Age of the microwave

The age of a microwave can affect how long it will last. A microwave that is used regularly usually lasts between seven and ten years.

However, if the microwave is in constant use, it may not last as long.

To ensure that your microwave lasts as long as possible, it is always recommended that you avoid running the appliance when there is nothing inside the cavity.

How can you extend the life expectancy of your LG microwave?

There are a few ways that you can help extend the life of your microwave, and the first is to keep it clean.

Make sure you are wiping it down after every use, or at least a couple of times a week.

Also, if there are parts that are worn out, you need to get them replaced as soon as possible so that the machine can work properly.

You want to make sure you are paying attention to your machine, and when there are issues, take the time to get them resolved.

How often does an LG microwave need to be replaced?

Your LG microwave should last anywhere from 5 to 10 years, or longer with some machines. It really does depend on how often you use it, if you are getting it repaired often, and the machine itself.

Some might not make it to the five-year mark, while others may go well past the 10-year mark.

Factors that will extend the lifespan of your LG microwave

Be careful with the door seal

The door seal is a delicate piece of equipment that keeps heat from leaking out. Both its airtight nature and its ability to stay clean and dry determine how long it will last. Here are some guidelines for keeping your microwave’s door seal in good shape:

  • Don’t touch the door seal with wet or dirty hands—this will cause the seal to wear out, which can impact how well it seals against the metal frame around it
  • Don’t use abrasive cleaners on the door seal—they can damage its texture (and thus, its ability to be an effective barrier)
  • Avoid using chemicals or abrasives on the door seal—these may also damage it over time

Cleaning and maintaining it

  • Clean your microwave with a damp cloth. Don’t use abrasive cleaners and don’t put sharp objects in the microwave, as they can damage the interior.
  • If you have a self-cleaning function on your LG microwave, use it every few months to clean away food residue that may be stuck inside.

Avoid damaging the power cord

You should avoid damaging the power cord. If you do, you should take measures to get it replaced.

Don’t overload it with food

Allow enough space for the food to move around inside.

If you have too much going on in there, it’s going to conduct heat unevenly, which can cause hot spots and cause your food to come out dry or burnt, and that’s not good for the longevity of your microwave either.

It’s also possible that some of your food will get cold since it won’t be exposed long enough to get hot at all.

Avoid slamming the door

The door is one of the most fragile parts of your microwave. It’s often made of plastic (more expensive models are made of metal) and has a rubber seal around it to keep heat from escaping out of the microwave when you cook food.

If you slam it shut, there’s a good chance that these seals will break and need to be replaced.

Cover food properly for cooking and reheating

Covering your food while it’s cooking or reheating is the best way to prevent splatter and help foods cook evenly. It will also prevent overcooking, drying out, and burning.

Avoid microwaving just water

The reason for this is that water molecules are smaller than food molecules and can escape the microwave.

When water evaporates, it can travel into the electrical components of your microwave and damage them.

Allow the microwave plenty of space to operate

If it’s too cramped, the microwave won’t be able to cool down properly, and you’ll risk overheating the microwave.

It will also be harder for the fan to vent hot air and moisture away from inside the appliance.

How much does an LG microwave repair cost?

The cost of a repair does depend on what the repair is and how easily the technician is going to be able to repair it.

Your repair could cost $50, or it could cost well more than the entire machine is worth.

A simple fix like a fuse or replacing the handle is going to cost very little, while a more complex repair like replacing the magnetron can run into the hundreds.

If you have a problem, it is best to seek the advice of a professional who can tell you exactly what the problem is and help you find the best solution for your specific machine.

Is it worth it to repair an LG microwave?

In some cases, it is worth repairing your machine. It really does depend on what type of issue you are dealing with.

Smaller repairs are going to be far less expensive than buying an entirely new machine. while larger issues are likely to cost more than a new machine would cost.

How do you properly clean an LG microwave

To clean your LG microwave, you want to make sure that you are wiping down any food spatter that is on the inside of the machine as soon as it occurs.

It is helpful to wipe down the interior of your machine at least once a week, ideally after every use. You also want to wipe down the front of the machine and the control panel.

Avoid saturating the front of the machine and putting too much cleaner directly on the front of the machine. Make sure you are wiping your microwave down often.

Is it safe to use a damaged LG microwave

This depends on the type of damage that we are talking about. A microwave with a damaged door is dangerous, and microwaves can escape into the room.

A microwave with a faulty control panel might still be usable. It is often best to either get your microwave repaired or replaced rather than try to use a damaged machine, both for your own safety and for the microwave’s safety as well.
