If I want to cook a microwave dinner that cooks for 9 minutes @ 50 percent power how do I do this?

Your circuit board has a small chip in it that allows the settings to be changed. The chip has gone bad. Usually any good electronics repair person can fix the problem. Ask your local dealer for a reference.

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

Hello

and/or circuit breakers, particularly in the case of recent power failure, and reset if necessary.


Unplug the microwave, wait 30 seconds and plug back in to the power supply to reset the microcomputer.


Open and close the microwave door firmly and press "Stop/Reset." Select a new cook time and press "Start."


Ensure a proper cooking temperature and/or time is chosen, as low cooking temperatures or short cooking times may prevent the microwave from heating food appropriately. Press "Power Level" to ensure the microwave is cooking at 100 percent power.


Contact an authorized service technician if the problem is still unresolved.

You have to put the cook time in first and then you press the power level button (just below the number 7 on the keypad) and put the power level in. The choices are 1 through 10. Fifty percent is probably power level 5. Once you have put in the power level, just push the Start button and it will start cooking.

Always use an oven bag is used to promote even cooking.

Microwave on MEDIUM (50% power) for 7 to 9 minutes per pound rotating dish every 15 minutes. Not recommended for turkey over 12 pounds
Use an instant-read thermometer after cooking. Turkey is done when thermometer reads 180 degrees to 185 degrees F for whole turkey or 170 degrees to 175 degrees F for turkey breast. Insert thermometer through **** in oven bag into inner thigh for whole turkey or into thickest part of breast for turkey breast.
For easy slicing, let stand 10 minutes after removing from microwave oven. To open, carefully cut or **** top of oven bag. NOTE Microwave directions were tested in 600 to 700-watt microwaves. Higher or lower wattage ovens may need adjustment in cooking times.

Press he power button and select a number 1-9. If you press 20 it will use 0 as the power. The numbers correspond to percentage of time the cooking energy is applied during the cycle. 5 is 50% so it will be cooking for 30 seconds out of each minute. 2 would be 20% and 9 = 90%. Hope this helps... Eric

Check the power output. Most are adjustable. With the microwave on, and cooking something, see if it is on 100%. If not, adjust it with the keypad.

The Start pad on the keypad may be starting to short. If so, a new keypad (membrane switch) would fix it.

We had this problem. It was installed improperly - to recirculate instead of to vent.
