    First, be sure your dishes & cups are truly microwave-safe.

    From the FDA: "Only use cookware that is specially manufactured for use
    in the microwave oven. Glass, ceramic containers, and all
    plastics should be labeled for microwave oven use."



    If they are, then your magnetron may be failing. Overheating is one sign of that.

    How old is it? Please reply back with your brand and model number so we can help you.

Assuming your turntable is wokring and your cups / dishes are microwave safe, then I would suspect the magnetron is failing.

That's a 2006 model, so the magnetron would definitely be under warranty.

But if it's more than 1 year old, you would have to pay for labor to get it replaced (if it's bad) and that would almost certainly not be economical.

For warranty issues or to find a local servicer, you can contact Sharp at 1-800-BE-SHARP (1-800-237-4277) or visit them online.

Why Does My Sharp Microwave Turntable Get Hot?

I hope you didn't run the microwave with nothing in the cavity, if you did, it will damage the magnetron.
The turntable dishes do get hot depending on the quality of the glass used to make it. Heat is caused by impurities in the glass.
If you run it with no food in the oven, the glass will try to absorb the energy with atastrophic results usually.

I need instructions for 10in. microwave browner

Only place I've found is here: CorningWare Browner Instructions

As these dishes were designed by Corning for a 650 watt over, you can recalculate preheat and cooking times for your oven with the following formula:

650/(your oven's wattage) x (listed preheat time or cook time)

For example, for a Corning MW-9 dish, they list 4 minutes maximum preheat time. I have a 1,580 watt oven. So 650/1580 = .41 x 4 minutes = 1.64 minutes and about a minute and a half preheat. (MAX).

We have a GE Spacemaker XL 1800 Microwave. There is dirt and moisture that has collected between the inside and outside glass. How can you clean this?

HELLO.

This is the solution to the cleaning issue.

1. Wipe the microwave inside and out with a soft cloth dampened with a warm, mild detergent solution. Rinse with a soft cloth dampened with plain water. Dry with a soft, dry cloth.

2. Put 2 cups of water into a 4-cup measuring cup. Place the measuring cup in the microwave, then heat on high for 5 minutes to loosen food particles that are stuck to the inside walls. Leave the measuring cup inside the microwave for 1 to 2 minutes, then remove and wipe the interior as in Step 2.

3. Remove the glass turntable and wash it in the sink with mild detergent or in the dishwasher. Handle carefully, as the turntable is breakable.

Thanks.

My microwave is completely dead. I have checked the fuse in the plug and it is fine. Any suggestions?

Hello,

What you are to do to solve the problem is to do a general troubleshooting on your oven below are instruction to follow.

The Microwave is a counter top model with a variety of preset cooking options, including timed cooking at a variety of power levels and sensor-cooking settings for popcorn, rice, beverages and single-serving reheating.

The sensor cooking and reheating features detect increasing humidity levels inside the microwave and automatically adjust cooking time for various types and amounts of food. This microwave also includes a turntable and an electronic control panel.



Instructions below are step by step solution for your oven

  1. Check to see if the microwave will start. If it will not start and the display panel is blank, you may have a power problem. Unplug the microwave and then plug it back in, making sure that all three prongs of the power cord are fully inserted into the wall outlet. If this doesn't work, check your home's fuse box. Reset the circuit breaker to restore if necessary.
  2. Ensure that the microwave door is fully closed. Press the Clear/Off button to cancel any previous cooking instructions. Re-enter your cooking program, including cooking time and food weight if necessary, and press Start.
  3. If "Err" appears on the microwave display, press the Clear/Off button and reenter your cooking program. The "Err" message will appear during the sensor-controlled programs (Popcorn, Rice, Beverage or Reheat) if the door is opened before steam is detected or if no steam was detected within the maximum amount of time allowed by the microwave. Be sure to leave the door closed during these programs, at least until time is shown counting down on the display panel.
  4. If your control panel will not work or if an "L" is displayed on the screen, press and hold the Clear/Off button for a full three seconds to unlock the control panel.
  5. If your sensor reheat program is resulting in under- or overcooked food, first try decreasing the amount of food in the microwave; the sensor programs are designed for single servings of food. The sensor reheat function works by measuring humidity inside the microwave--do not use a tightly-covered dish with this setting because no moisture will be able to escape and the food will overcook. Be sure that cooking containers are dry; moist containers will increase the humidity in the microwave and mislead the sensor, resulting in undercooked food.
  6. If your turntable is not rotating, first check to ensure that your food container is positioned so that it can freely rotate without hitting the microwave's interior walls; using a smaller food container can fix this problem. If the turntable still will not rotate, lift the turntable from its support and replace it carefully, ensuring that it rests evenly on its support.
Good luck.

Thank you and thanks for using fixya.

Top of over-the-range microwave hot to touch; normal?

A little over 100F is hotter than most folks can stand to touch, so it may not be seriously hot.

But if you're concerned, you might see if your dealer will let you test another one or a similar model at the store to see if it also gets that hot.

Otherwise, you can return it to be safe or you can contact Panasonic consumer electronics support here or at 1-800-211-7262 to ask them about it.

When we first turn on the microwave there is like a mini-explosion and a fiery spark, but after that the microwave goes through its cycle and cooks the food. But we are afraid to try it again.

pls do not use any aluminum or metal material INSIDE the microwave, this can cause the problem

I assumed, but pls consider the ff info...

Be sure to use nonmetal utensils in the microwave.

For microwave cooking, cut meats and vegetables in uniform sizes to make sure that they cook evenly.

Paper plates, cups, and napkins can be used in the microwave. But don't use foil-lined paper products, paper towels that include nylon or synthetic fibers, or newspaper.
When using plastic roasting or cooking bags in the microwave, discard the wire twist tie and use a plastic fastener or a piece of string instead.

To ensure that food cooks fully and evenly in the microwave oven, stir food and turn dishes periodically while they're cooking.

Microwave oven problem

In most cases, this is a problem with the inverter or a bad magnetron.

Due to the lethal voltages used and produced, I do not recommend that an inexperienced person work on these.

I would recommend that you contact your nearest Panasonic-authorized servicer. You can find one here:

Microwave does not heat food placed in the center of the turntable. Leaves a cold spot in the middle of the food.

This is normal. That's why I always recommend to my customers that the food be placed slightly off-center on the turntable. An analogy I refer to is stirring paint: If you stir paint with a stick by simply rotating the stick in the center of the can, it's far less effective than pulling the stick around an imaginary circle halfway bewteen the center and the edge.
