6 common problems with microwave - Ideas by Mr Right (2024)

FAQs

What are the most problems with a microwave? ›

Issues with the door switch, internal fuse, magnetron, diode, high-voltage capacitor, and electronic control board are common causes of microwave malfunctions, requiring repair or replacement by a technician.

Misset functions or broken parts are often to blame when your microwave is not heating up. Settings like Control Lock Mode, Demo Mode or power levels set too low may be preventing food from cooking, or more complex causes like a broken magnetron, door switch or high voltage diode could be the source of the problem.

Heat your food properly

Microwaves do have some downsides. For example, they may not be as effective as other cooking methods at killing bacteria and other pathogens that may lead to food poisoning. That's because the heat tends to be lower and the cooking time much shorter. Sometimes, food heats unevenly.

While microwave oven radiation doesn't cause cancer, it can cause painful burns if you're exposed to them. Microwave radiation can heat body tissue the same way it heats your food. However, these burns are only caused when you're exposed to high levels of microwave radiation.

Microwave Wisdom: Why Not to Microwave Eggs in Shells

Microwaves heat so quickly that steam builds up faster than an egg can 'exhale' it through its pores and the steam bursts through the shell. For the same reason, when microwaving, always prick the yolk of an unbeaten egg with the tip of a knife or a wooden pick.

You don't want to put carrots in the microwave. "Arcing is sparks produced inside the microwave from the microwave's reaction with metallic materials. Carrots may contain minerals from the soil that can cause this spark," she says. And the same goes with hot dogs!

Microwave transmission is affected by wave effects such as refraction, reflection, interference, and diffraction. Microwaves can pass through glass and plastic.

Why does tomato sauce pop in the microwave? ›

Tomato Sauce

Heating tomato sauces in the microwave often ends in splatters. The heat and steam produced by the sauce when warmed has a difficult time escaping through the thick sauce or around pieces of ingredients. The steam builds up until it's powerful enough to burst through—and onto the microwave walls.

Probably the most common issue of any microwave is when the plate doesn't turn. The turning plate helps cook and reheat your food evenly, so it's a major headache when it's not working. Usually, the problem could be from something obstructing the spinning assembly.

Microwaves don't produce the best tasting food, they might destroy nutrients, and there is a possibility that they might release harmful radiation.

If all the sounds and displays operate as usual, but no burning odor or smoke, and appear to be doing the cooking program, but absolutely no heating of the usual food contents happens; it might be a bad magnetron, or a bad high-voltage power transformer or the HV-rectifier.

Understanding the most common parts that can break in a microwave, such as the magnetron, door switches, turntable, control panel, and high voltage components, can help users identify issues early and seek professional repairs or replacements.

With normal usage for an average family and good maintenance, a microwave often lasts for 7 to 8 years. If the microwave is used less frequently by a single person or a couple and is well-maintained, the lifespan can increase to up to 10 years.

While it sometimes is impossible for the purchaser of a magnetron to understand why the unit failed, most breakdowns observably fall into one of three broad sources: Poor materials and/or workmanship. Improper use. Ordinary wear and tear.

Microwaves are powered by a device called a magnetron. After about 2000 hours, this device will burn out and you'll need a new microwave. Occasionally the fuse could blow, which is often caused by a defective part like the magnetron or door interlocking mechanism.
