The waveguide cover, found inside the oven interior, is made from mica, so it requires special care. Keep the waveguide cover clean to make sure of good microwave performance. Carefully wipe the surface of the cover with a soft damp cloth to remove any food spatters immediately after they occur.
Additionally, it stops moisture and food particles from getting into the “workings” of the microwave. Replace the waveguide cover if it is burnt, chipped, or cracked. Do not operate a unit with a burnt, chipped, or cracked waveguide cover or without the waveguide cover in place.
What happens if the waveguide cover is damaged?
Although strong and tough when new, over a period of time this cover absorbs moisture and food debris and becomes soft or breaks. If moisture or food embedded in it starts burning it will go from bad to worse quite quickly and if not replaced can cause irreparable damage to the microwave.
Dirty or Damaged Waveguide Cover: If the microwave hasn’t been cleaned, food particles and grease on the waveguide can cause sparking in your microwave. The sparking is caused by the magnetron burning the food fragments stuck to the waveguide. The waveguide cover can also get damaged by frequent sparking.
Can I use my microwave without the waveguide cover?
The cover is actually a wave guide cover mica plate which is an important accessory in microwaving. Please leave the cover inside the microwave and do not use the product without it.
What is a waveguide cover made of?
Microwave oven waveguide covers sometimes become carbonised and cause sparks to occur inside the cooking cavity. These covers are generally made of mica and are easily replaced.
Can you tape a waveguide cover?
Also, be sure to keep the door closed in case a fire breaks out or if you see a microwave spark. Can I tape a waveguide cover? Tape may not be microwave-safe and could contribute to damaging a microwave’s electrical components. Use an actual microwave waveguide cover instead.
What is the cardboard looking thing in my microwave?
This is a wave guide cover and it’s not actually cardboard it’s a material called Mica. It prevents steam and food particles from interacting with the electrical components within the microwave oven.
What is the shiny cardboard in a microwave?
On the side of the interior of your microwave is a cardboard plate. This is a mica plate that prevents short circuits in your microwave.
What metal is waveguide?
It’s a rectangular, circular or elliptical metal pipe made from materials with high electrical conductivity (copper and brass, partially plated with silver or gold or covered with a thin layer of carbon fibre).
Should I remove silver cardboard from microwave?
No. This is a part of the microwave. Removing it will damage the microwave and void its warranty.
Why did my microwave cover melt?
Different plastics react to the microwave in different ways and fatty foods, in particular, like meats and cheeses, reach very high temperatures and may cause the plastic to warp or melt. This in turn has the potential to cause a chemical to seep out of the plastic and into the food.
Failing to cover what you’re cooking or reheating affects the consistency and heat distribution of the food, potentially leading to unwanted results, explains Today. Because heat circulates inside the oven, lightly covering the plate or container helps the food heat more evenly without overcooking.
What material is a microwave waveguide?
Typically waveguide is made of brass, copper, silver, aluminum, or any metal that has low bulk resistivity. It is possible to use metals with poor conductivity characteristics, if the interior walls are properly plated. It is even possible to make plastic waveguide!
What can I use if I don’t have a microwave cover?
Paper towels allow steam to escape while they promote even heating and prevent spatters.
Waxed paper holds in heat for faster cooking without steaming the food.
Plastic wrap holds in steam and heat.
Can you replace mica in microwave?
Installation is pretty simple: You pop out the old microwave sheet, get a pencil and trace the old shape onto the new plate sheet. Then cut along that shape, and pop the new sheet in.
Why is my microwave sparking with nothing in it?
In most cases where sparks appear in the appliance, it is likely because you have accidentally left a piece of metal in the microwave. When the appliance is working, this will cause sparks to fly, and the metal should be taken out as soon as possible.
Do I remove the cardboard from inside microwave?
The cardboard covers the waveguide system that feeds microwave energy into the cavity and should not be removed. The microwave should not be used for any function if this cardboard cover is not in place. If removed, it would require service to replace.
What happens if you remove the microwave cover?
It could be EXTREMELY DANGEROUS to operate a microwave oven with the cover off, much more dangerous even than working on raw mains electricity. Even after switching off, the capacitor may hold sufficient charge for an extended period to give you a DANGEROUS, possibly LETHAL electric shock.
What are the black dots on microwave?
First up—the black dots on the microwave. It’s designed to prevent electromagnetic energy from escaping the microwave and protects you from radiation. That little hole in the pen cap—it can actually save your life.
What happens if you remove mica plate from microwave?
It is an airwave guide cover that assists the microwave in distributing the heat evenly. Removing this cardboard plate may cause damage to the inner liner of the microwave.
Why does aluminum foil destroy a microwave?
The electric fields in microwaves cause currents of electricity to flow through metal. Substantial pieces of metal, like the walls of a microwave oven, can usually tolerate these currents without any problems. However, thin pieces of metal, like aluminum foil, are overwhelmed by these currents and heat up very quickly.
What does parchment paper do in microwave?
You can safely use parchment paper in the microwave. The silicone coating on the paper helps prevent it from catching fire and will not release harmful chemicals into your food. However, you should avoid using parchment paper that is crumpled or torn, as this could create hot spots that could cause a fire.
What is the plastic film on the inside of a microwave door?
The inside of the microwave door is covered with a thick, clear plastic sheet that should not be removed. The purpose of this plastic is to prevent any interference with the metal screen in the door.
What is the metallic card in a microwave?
A waveguide cover is a metallic like sheet that allows the energy waves from the magnetron through to cook your food in your microwave. They can become burnt or accidentally damaged, and if either of these has happened you may notice sparks or arcing in your microwave.
Can a broken microwave leak radiation?
If microwave ovens are used while broken or altered, it is possible for them to leak electromagnetic radiation. Microwave radiation leaks are hard to detect because you can’t smell or see microwaves.
Why did my microwave almost explode?
There are a few common causes for an explosion in the microwave: Cooking unauthorized food: Some foods aren’t recommended for microwaving because of their structure and shape. If you try to cook a shelled egg, there will be less space for the cooking egg to expand, leading to the steam formation and pressure buildup.
Is microwave radiation harmful to humans?
Microwave radiation can heat body tissue the same way it heats food. Exposure to high levels of microwaves can cause a painful burn. Two areas of the body, the eyes and the testes, are particularly vulnerable to RF heating because there is relatively little blood flow in them to carry away excess heat.
Why do people use microwave covers?
It serves several purposes. It eliminates the splattering of food around the inside of a microwave oven, which is hard to clean, unsightly and unsanitary. It prevents keeps food from drying out by keeping moisture contained.
Can you microwave on a paper towel?
Yes, but be careful. If heated for more than several minutes at a time, paper towels can catch on fire. Most paper towels are microwave safe. To reduce the risk of fire, heat your food in two-minute intervals.
