5-10 years with an average of 8 years.
Microwave ovens vary in price according to their type and function, as of 2011. Countertop models range in price from $50 to $450. Built-in models are good for kitchens that are short on counter space and range in price from $200 to $1,100 up to $2,000 with a convection feature. But it is the lifespan of the magnetron or transformer, the two devices that regulate the amount of radiation flow for cooking, that impact the longevity of a microwave. For an appliance that got off to a rocky start, the microwave is a widely used and must-have gadget for many modern kitchens. Over 90 percent of American homes have them, according to House and Garden magazine. The appliance comes in a range of sizes and features but has a relatively short lifespan. But it is the lifespan of the magnetron or transformer, the two devices that regulate the amount of radiation flow for cooking, that impact the longevity of a microwave. The life span of the sun is 10 - 12 billion years and it is now 4.6 billion years old which makes the sun middle aged. The size of the star is not as important as to the … class of the star. A star like the sun which is a Gv2 class, yellow dwarf has a life span of about 10 billion years. Where as Alpha Centuari B is an Orange Dwarf about the same size as our sun but is a Kv5 class Star, and has a life span of between 15 and 30 billion years. 4 people found this useful. Microwave ovens have one of the shortest lifespans of among common appliances, about nine years, according to a study by the National Association of Homebuilders. But it is the lifespan of the magnetron or transformer, the two devices that regulate the amount of radiation flow for cooking, that impact the longevity of a microwave. Microwave. In the typical 10-year life span of a microwave, the most common problem is a gradual loss of power. This is not a major concern, as most people tend to adjust the time they heat food accordingly. A more serious problem of older microwaves, however, is radiation leakage. If you’re not willing to take the chance, that’s why they offer extended warranties (although I don’t recommend them in general). According to Mr. Appliance, the life span of the microwave oven is 5-10 years with an average of 8 years. The gas water heater can live 5-13 years with an average of 9 years of use. Its important to take care of your appliances to extend their useful life. For a refrigerator this means cleaning the coils and gaskets regularly. That microwave needs the filters in the vent hood cleaned monthly. Charcoal filters need to be replaced every 6-12 months. Average Lifespan. Microwave ovens have one of the shortest lifespans of among common appliances, about nine years, according to a study by the National Association of Homebuilders. There are a number of parts that can cause a microwave to temporarily malfunction, most commonly, the fuse. But it is the lifespan of the magnetron or transformer, the two devices that regulate the amount of radiation flow for cooking, that impact the longevity of a microwave. Some claim a typical magnetron tube has an average life of 2,000 hours of operation, and suggest that if you use a microwave oven for a total of 15 minutes every day, it would take 22 years for it to reach the 2,000-hours-of-operation point. 2. Your microwave oven door has problems. The door to your microwave oven is a vital safety component that’s carefully designed to contain radiation. The door interlock switches a signal that the door is shut, which means it’s safe for the unit to start heating. A microwave oven, commonly referred to as a microwave, is a kitchen appliance that heats and cooks food by exposing it to electromagnetic radiation in the microwave spectrum. This induces polar molecules in the food to rotate and produce thermal energy in a process known as dielectric heating.  According to Mr. Appliance, the life span of a microwave oven is 5-10 years with an average of 8 years. Ela Schwartz with Home Sweet Solutions claims there are three major signs to watch for that may indicate it’s time to replace your microwave oven: 1. Your microwave makes loud noises while cooking. 2. Your microwave oven door has problems. The door to your microwave oven is a vital safety component that’s carefully designed to contain radiation. The door interlock switches a signal that the door is shut, which means it’s safe for the unit to start heating.
