I have power, but when I start to cook it shuts off and needs to be reset. It only cooks for 2 seconds and then shuts off. Did I blow an internal fuse ?

you will need to set the microwave to cook at 65% to 70%. this way the microwave only cooks 65 to 70 second out of 100 seconds giving the meat time to cook internally. just make sure the internal temperature reaches 165 degrees. before you remove it and and consume.

This is from Page 16 in the users manual...

For simple, one-stage cooking, you only need to set the cooking time. The power level is automatically set to High.

If you want to set the power level to any other level, use the Power Level button.
1. Use the number buttons to set a cooking time. You can enter a time from one second to 99 minutes and 99 seconds. To select a time greater than one minute, enter the seconds too. (For example, to set a cooking time of 20 minutes, enter 2, 0, 0, 0.)

2. If you want to set the power level to a level other than High, press the Power Level button, and then use the number buttons to enter the power level.

3. Press the ENTER/START button to begin cooking. If you want to change the power level, press the STOP/ CLEAR button before you press the ENTER/START button, and then enter all the instructions again.

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.

There are a couple of safety thermostats under the cover that can shut down power. One is on the magnetron tube (the microwave source) in case the tube overheats. Another one is on the cooking cavity to shut the oven off if something catches fire while cooking. These interrupt the power, same as unplugging the oven, which is why you need to reset everything.

It's possible that because of the oven's age, the magnetron tube is weak enough that it's overheating when it tries cooking. As the tube ages it works harder and gets hotter. But it usually takes more than a couple of seconds for the thermostat to operate. These thermostats sometimes go bad on their own and operate too soon.

Other possible causes for power loss are a fuse loose in its holder or intermittent connections to the control circuit board.

Since troubleshooting power problems means working on the oven with the cover off and the power on, you should leave repairs to a professional. MICROWAVE OVENS USE HAZARDOUS VOLTAGES WHICH CAN KILL YOU. Let a professional check the oven and give an estimate for the repair. Given the age of the oven you may want to consider replacing rather than repairing this one, but let cost be your guide.

magnetron is leaking internally, do not use until magnetron is replaced. the mag creates interference with the control board and resets it

The owner's manual is here. On page 10 we find:

COOKING IN ONE STAGE
1. Press the POWER button; the Microwave and High
Cook indicators will light and “PL 10” will light in the
display.
2. Press the POWER button different times to set the
desired power; the display will show the percentage
you chose. If selecting power level 70%-10%, the
Low Cook indicator will light instead of the High
Cook indicator.
3. Press number keys to set the desired cooking time.
OPERATION(CONTINUED)
4. Press the START/+30SEC. button to start cooking;
the Microwave and one of the Cook indicators will
blink and the display will countdown the remaining
cooking time in minutes and seconds. It will beep
five times when cooking is completed.

Hi! I just purchased the same microwave, and came online to find the solution. I was then able to find the correct answer to this problem. On this model, Emerson does not put a "time cook" button for odd cook times such as 15 seconds. Instead, they have you push the "Power Button" prior to setting the cook time.

If you want to cook on full power, press the power button once, and then enter your cooking time and press start. If you want to cook on 50% power or 30% power or something like that, push the "Power Button" several times until the appropriate power level is displayed, then enter the cook time and press start.

The reason that it starts up right away when *********** pushes the 1 button is because Emerson has the quick cooking feature for 1 minute through 6 minutes. You only have to push the number once to get the 1 minute cook time or anywhere through 6 minutes respectively.

Hope this helps!

this would be the digital control board that would need to be replaced

It could have been steam or humidity.

If this is an over the range model, be sure you always use the hood vent exhaust fan when you're cooking on the stove top.

Whether it's a counter top or over the range top, always be aware that the cooling fan is running when it's cooking.

When in doubt feel for air flow through the vents.

Good luck.

Please try on some other power point as if there is loose contact or sparking in point which cause to switch off as soon as you start because of heavy current drawn by oven and clock also resets. If not solved even then must have some short circuit or over loading in timer circuit or magnetron. in this case you have to call for a service engineer.
