Microwave Ovens Can Be Zapped By Age Factors | Penn State University

UNIVERSITY PARK, Pa. — We all know when age is creeping up on us — joints creak, hair’s-breadth goes grey, wrinkles appear. But how do you know when your microwave oven is nearing retirement age ? A food scientist in Penn State ‘s College of Agricultural Sciences offers a few tell-tale signs of appliance refuse .
“ Microwave ovens of any price easily should death 10 years or more, ” says Swamy Anantheswaran, associate professor of food skill. “ But there will be changes in operation — normally a refuse in power so gradual that consumers never notice it. ”
The Magnetron
Anantheswaran explains that the magnetron, the electrical element that converts electrical energy into microwave department of energy, will not maintain the like power levels over meter. “ If a new microwave oven boils a cup of water in one moment, after five or 10 years it may take 90 seconds, ” Anantheswaran says.

Although microwave ovens lose baron as they senesce, Anantheswaran says most consumers unconsciously adjust cooking times without realizing the oven is not performing as efficiently .
“ You can replace the magnetron in a microwave oven, ” Anantheswaran says. “ But I do n’t recommend it. It would credibly be cheaper to buy a new microwave oven. ”
Anantheswaran says magnetrons can interfere with cellular phone transmissions because both products emit microwaves within the same frequency compass .
“ The cellular phone industry would like magnetrons to confine their department of energy discharge to a more specific frequency to prevent hindrance or make noise escape onto telephone calls, ” he says. “ If the microwave oven manufacturers have to develop more frequency-specific magnetrons, the price of microwave ovens will go up. ”
The Power Fuse
All microwave ovens are outfitted with a world power fuse designed to cut power to the oven if circuits overload. Anantheswaran says ovens can overheat and blow the baron fuse. “ If the oven is used to cook foods with very little moisture, the hotness can build up in the oven pit and overheat the circuits, ” he explains. “ If you ‘re cooking a dry fabric, such as popcorn, give the oven a break before popping another pocket. ”
A fellate might fuse can be repaired for $ 10 to $ 20, but Anantheswaran says consumers should not try to repair a microwave oven themselves. “ These appliances are not meant to be serviced at home, ” he says. “ The problem may be something other than a fuse. ”
Gasket Leakage

Anantheswaran says microwave ovens can leak microwave radiotherapy if the gaskets around the door and early parts of the oven become wear or pitted .
“ several companies make products that can measure whether microwaves are leaking from an oven, ” Anantheswaran says. “ These products, some of which are clientele card-sized flat cards, will change tinge if microwaves are leaking. ”
Anantheswaran says consumers should consult an appliance haunt shop class to replace a tire gasket .
“ many microwave oven parts become barely after a few years, ” he says. “ It ‘s improbable you ‘ll be able to well find a gasket for an older oven. Get an adept opinion from the technician to see if it ‘s time to buy a raw matchless. ”
Carousels
Anantheswaran says rotating carousels can jam, peculiarly when orthogonal casserole dishes are besides boastfully to be turned by the carousel. “ Most glass platforms are shaped like a shallow bowl, ” he says. “ In some ovens you can flip the glass chopine over, allowing the carousel mechanism to rotate freely beneath the glass. The casserole dish wo n’t turn, but the heating system will be the like. ”
Anantheswaran, who has used the same microwave oven in his home for the by 12 years, says homeowners should feel no race to replace older ovens if they need a minor animate. “ If you are used to the way your car runs, why replace it ? ” he says. “ It gets you where you want to go. ”
