Microwave power interruption

Everything works until you start to cook, then after about 3 sec. the power cuts off and the display says there is a power failure, check your food. There are not power issues other than that.

Our Advantium 120 oven (model # SCA1001KSS 02, Manufactured June 2008)is not working. Began w/ time not coming on when cooking and just a little green microwave light shows while cooking.

Typical of a control microchip failure caused by a power surge. With a microwave as old as yours, it is safest to simply replace the entire oven rather than attempt to fix it, as older magnetrons are likely to fail.

Why did my whirlpool microwave display quit, everything else works. less than 2 years old

Over the range ovens of all brands are prone to failure of the electronics due to heat and steam from the food that's cooked on the range below them. It's not extremely common, but you do see more of these types of failures on these as opposed to counter top models.

Emerson microwave not working 900 watts

The Emerson MW8999SB 0.9 cu. ft. 900 watt Microwave Oven is relatively compact, and certainly inexpensive, but doesn't skimp on functionality. We were surprised at all the options you get with this little microwave. It's only 20 inches wide, 11.3 inches high and 16.1 inches deep yet. The interior can still accommodate a regular size dinner plate or small (10-inch-square or round) casserole. Plus, there are 10 power levels, eight one-touch function buttons, six Express Cook settings, timed and automatic defrost options, and a rotating glass turntable to circulate the food for more even cooking.

We were very pleased with the performance of the Emerson MW8999SB. It did a fine job heating water for tea, cooking a couple of baked potatoes, reheating leftovers and steaming fresh vegetables. Even the automatic defrost proved surprisingly efficient, letting you enter the weight of the item(s) to be defrosted (4-100 ounces) for easy operation. Chicken breasts were almost fully defrosted after one cycle. We needed to stop and separate the food pieces to finish the defrost cycle.

The unit is styled mainly in black but has stainless steel trim around the door and control panel. The smooth touchpad control panel is attractive and easy to wipe clean. We loved the one-touch Express Cook buttons, which let you activate the unit at 100 percent power for 1-6 minutes, by pressing the corresponding number pad. We also appreciated extra touches such as the Start/+30 sec. button, which can be used to start the oven or add an extra 30 seconds each time it is depressed.

It's hard to go wrong when the functions are so simple. The only tricky part was identifying certain codes used on the display screen. When changing the power level, for instance, PL10 is displayed on the screen. Pressing the button additional times lets you toggle through the different levels. Likewise, the Auto Cook settings may need to be pressed multiple times to obtain the correct weight or portion for the food being cooked.

We were amazed that a machine costing so little also offered two-stage cooking, which lets you start cooking (or defrosting) on one setting and finish on another. All in all, the Emerson MW8999SB is an excellent value.

Pros: Touchpad controls, eight one-touch function buttons, six Express Cook settings, two-stage coking option
Cons: Limited interior capacity can only accommodate dishes up to 10 inches, no sensor

Not heating


Power Supply

Check whether there is a proper power supply. Look to see whether the cord is connected to a grounded 3-prong outlet and the cord is fully plugged in. If the electrical system is built-in and no power cord is visible, replace or reset the household fuse or circuit breaker.

Microwave Functions

Some basic microwave operational steps may affect whether the microwave is heating. Open and close the microwave door, as the unit will not function with the door open, and push "Stop/Clear" to cancel any previous settings, such as the timer, which do not heat the microwave oven.

Setting the Microwave

Once the power to the microwave has been reset, or verified as working, and the microwave is ready to run, select a new cook cycle and press "Start" to see if the microwave begins to run and cook food as expected. Allow the food to cook for the alloted time and then open the microwave door and check to see if the food has cooked or heated. Choose a longer cooking time and restart the microwave if food is heating but is cooking slowly.


If all efforts to troubleshoot the function and power to the microwave still do not get the appliance heating food as expected, there may be a repair issue that needs to be addressed. Contact professional technician for advice.

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


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.

Microwave cuts off after heating for about 3-4 minutes

There is a overtemperature device inside that is shuting you down until things cool off. Take the cover off and clean up everything as much as possible. Grease from the cooking can get all over everything inside and collect dust buildup enough to obstruct the airflow and cause overheting.

LG 1925 Microwave suddenly stopped cooking, other functions work fine!

What you said about the the clock leads me to suggest that you first unplug it for a few minutes then plug it back in. It may just need a good reset. If you don't have your owner's manual you can download one here: The mention of odor concerns me. It may just be a bit of food or grease on the waveguide cover, which is a small sheet or panel on the wall or ceiling of the cooking cavity, but it may indicate the failure of a part in the high voltage section. You may have an intermittent door switch. You can see some of my other responses for info on how to get our important text file that helps you diagnose and repair door switches and gives important safety tips.
