Which household appliance has the shortest lifespan?

Not all appliances are built to last the same amount of time, and some seem to have a shockingly short shelf life. We’ll explain which household appliance tends to kick the bucket first,  and why that happens.

Important: The information in this article may not apply to your specific appliance model.

What household appliance has the shortest lifespan?

The household appliance with the shortest lifespan is typically a microwave, with an average lifespan of about 5 to 7 years. Factors like frequency of use, quality of the appliance, and maintenance can influence this. Microwaves experience significant wear and tear due to constant heat and electrical use, leading to relatively quick degradation compared to other household appliances.

Small appliances with the shortest lifespan typically include kitchen appliances like toasters, blenders, and coffee makers. These tend to have more limited warranties and are generally less durable compared to larger household appliances like refrigerators or washing machines.

Which microwave style is most reliable?

Countertop microwaves generally tend to be more dependable than other styles like over-the-range or built-in models. Here’s why:

• Simplicity: Countertop models usually have fewer components and simpler designs, which reduces the likelihood of mechanical issues.
• Ease of replacement: Since they aren’t built into cabinetry, countertop microwaves are easier to replace if something goes wrong, and they don’t require professional installation.
• Cost-effective: These models are often less expensive, so even if they experience issues, replacing or repairing them is more affordable compared to built-in or over-the-range styles.

The brand and quality of the microwave play an important role in reliability too. Reputable brands tend to have positive reputations for reliability across their countertop models.

Why do appliances break?

Appliances break for a variety of reasons, often due to a combination of wear and tear, improper usage, or manufacturing defects. Here are the key factors that contribute to appliance breakdowns:

1. Wear and tear

• Over time, components in appliances degrade with regular use. Moving parts like motors, belts, and gears can wear out, and heating elements can weaken. As they age, parts can corrode, deteriorate, or become less efficient, leading to breakdowns.

2. Electrical or mechanical issues

• Appliances that generate heat, like microwaves, ovens, and dryers, can experience problems due to overheating. Electrical components may short-circuit, or motors can burn out.
• Sudden spikes in electricity, like during storms or electrical malfunctions, can damage sensitive electronic components inside appliances.
• Motors, fans, pumps, and compressors in appliances like refrigerators, dishwashers, and washing machines can fail due to wear, poor maintenance, or overloading.

3. Improper use

• Appliances like washing machines, dryers, and dishwashers are often damaged when overloaded beyond their capacity. This puts strain on their motors and mechanical parts.
• Lack of regular maintenance, like cleaning filters, clearing lint traps, or descaling, can cause appliances to work harder than they should, leading to faster breakdowns.
• Using incorrect detergents, accessories, or replacement parts can damage appliances, especially in devices like dishwashers, washing machines, and vacuum cleaners.

4. Poor quality

• Appliances made with low-quality components or materials are more prone to break. Budget models often have a shorter lifespan compared to higher-end appliances.

5. Environment

• Excess moisture can cause rust, mold, or damage to electrical components in appliances like refrigerators, washing machines, and dishwashers.
• Dust buildup in appliances like fans, air conditioners, or even the cooling coils in refrigerators can cause overheating and reduce efficiency.
