How Many Years Should a Microwave Last? Must Know

The average lifespan of a microwave oven is about eight years, but it can vary depending on how you use and maintain it. Microwave ovens are convenient and versatile appliances that can help you prepare meals quickly and easily. However, like any other appliance, they have a limited lifespan and need proper care to function well and safely. In this article, we will explore some factors that affect the longevity of your microwave oven, some signs that indicate you need to repair or replace it, and some tips to extend its lifespan and performance.

Factors That Affect the Lifespan of a Microwave Oven

There are several factors that can influence how long your microwave oven will last, such as:

  • Frequency of use. The more you use your microwave oven, the more wear and tear it will experience. A microwave oven that is used several times a day by a large family will likely have a shorter lifespan than one that is used occasionally by a single person or a couple.
  • Maintenance. Keeping your microwave oven clean and well-maintained can help prevent damage and extend its lifespan. This includes wiping spills and splatters, cleaning the grease filter, using microwave-safe dishes and containers, and avoiding metal objects and other materials that can cause sparks or fires.
  • Type and quality. Different types and models of microwave ovens may have different features, capacities, and wattages that can affect their durability and performance. Generally, higher-quality and more expensive microwave ovens tend to last longer than cheaper and lower-quality ones. Also, some types of microwave ovens, such as convection or combination ovens, may have more complex components that can break down more easily than standard ovens.
  • Power surges and outages. Power fluctuations can damage the electrical components of your microwave oven and shorten its lifespan. To protect your microwave oven from power surges and outages, you should use a surge protector and unplug it when not in use.

Signs You Need to Repair or Replace Your Microwave Oven

Sometimes, your microwave oven may show some signs that indicate it needs to be repaired or replaced, such as:

  • Cooking times are off. If your food takes longer or shorter than usual to cook, or if it is unevenly cooked, it may mean that your microwave oven is losing power or has a faulty magnetron, which is the part that produces the microwaves.
  • The door seal is compromised. The door seal, or gasket, is an important safety feature that prevents microwaves from leaking out of the oven. If the seal is loose, damaged, or dirty, it can pose a risk of radiation exposure and reduce the efficiency of your microwave oven.
  • The keypad or display is not working. If the buttons or the display of your microwave oven are not responsive, it may indicate a problem with the circuit board or the wiring. This can affect the functionality and safety of your microwave oven.
  • The oven makes unusual noises or smells. If your microwave oven makes loud or strange noises, such as buzzing, humming, or clicking, or if it emits a burning smell, smoke, or sparks, it may signal a serious problem that can cause a fire or an explosion. You should immediately turn off and unplug your microwave oven and contact a professional for repair or replacement.

Tips to Extend the Lifespan of Your Microwave Oven

To get the most out of your microwave oven and make it last longer, you should follow these tips:

  • Ensure there is adequate air circulation around the oven. Place your microwave oven in a well-ventilated area and leave some space around it to prevent overheating and damage.
  • Use the appropriate power level and cooking time. Follow the manufacturer’s instructions and guidelines for using the correct power level and cooking time for different types of food. Overcooking or undercooking food can damage your microwave oven and cause foodborne illness.
  • Check the food temperature with a thermometer. Microwaves can cook food unevenly and leave cold spots where harmful bacteria can survive. To ensure that your food is cooked safely and thoroughly, you should use a food thermometer and test the food in several places to make sure it has reached the recommended safe temperature.
  • Use microwave-safe dishes and containers. Only use dishes and containers that are labeled as microwave-safe and avoid materials that can cause fires or explosions, such as metal, aluminum foil, or plastic wrap. Also, avoid using dishes or containers that are cracked, chipped, or warped, as they can leak chemicals or break in the microwave oven.
  • Cover the food with a lid or plastic wrap. Covering the food in the microwave oven can help cook it evenly and prevent splatters and messes. However, you should leave a small gap or vent to allow steam to escape and avoid creating too much pressure. You should also avoid letting the plastic wrap touch the food, as it can melt or release harmful substances.
  • Clean the oven regularly. Cleaning your microwave oven after each use can prevent food and grease buildup, which can absorb microwaves and cause damage or fires. You can use warm water and soap, vinegar, or lemon juice to clean the inside of the oven. You should also clean the grease filter, the door seal, and the exterior of the oven periodically.
  • Call a professional for repair or replacement. If your microwave oven has any signs of damage or malfunction, you should not attempt to fix it yourself, as you may expose yourself to radiation or electric shock. You should contact the manufacturer or a qualified technician for repair or replacement.
