E4 means your thermistor (temperature sensor) is shorted or caked with grease, making it look shorted.

Normally you can get Samsung parts here: http://www.samsungparts.com/search/search.asp

But that part does not show up on a search so you'll probably have to call them:

How do I change temp and time while food is cooking?


all is explained in the user manual
if you have just put food in the even and pressed the start several times to get a number of minutes to cook but want to increase that time just press start again the number of times that you want the cook time to increase
for example :-
you put a frozen pie in the oven and your start operates in 30 second increments and you have pushed it 3 times and it starts cooking-BUT - you read the cooking instructions and it says cook for 4 minutes, just press the start another 3 times while it is cooking
the new cook time will show on the display

My Sharp microwave convection oven (R-967M / R96STM) cuts out during convection pre-heating and cooking, It appears it stops heating after 1 min. If the START button is pressed again the oven starts...


Also the fact it is a convection oven could mean the oven temperature sensor is not picking up the oven temp. it is not telling the machine it is there by the board seeing its resistance, the unit will shut off as a safety feature. The oven sees temperature by reading the value of a temperature dependent resistor. As the temperature changes so does the value of the component ( oven temp sensor) that way the unit determines the temperature inside the unit. Sometimes those sensors will break since they are in the area with the heat and moisture, they get old and break.

During cooking, the microwave will work for about 3 minutes then completely shut down.There appears to be a complete power failure.After the units sits for about 5 minutes,it resets itself and you can cook...


sounds like the cooling fan has came adrift or stopped working , this will cause the magnatron ( the microwave generator ) to overheat tripping the over temperature stat ,so fix the cooling , but be sooooooooooooo carefull in there , microwaves + really high voltages , not really a job for a non electrician/microwave tech

I have Emerson Microwave #mw8999sv which has the Express Cook option- cooking 1 - 6 minutes. How do I cook for 1 minute 30 seconds, etc.? Thank you.


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.

Emerson microwave, #MW8119SB, push start button to start cooking


Replace the fuse with a ceramic fuse from Home depot! costs less than $3 and it will fix the problem. I had all the same problems as everyone else, you name it my microwave had it! you must remember replace it with a ceramic fuse! not a glass one. I know people say its the switchboard and all that nonsence but I promise you, the fuse plays a majoe roll in the microwave not working properly. Even though it doesnt look broken, a junky fuse can cause your appliance to do very strange things. I replaced mine 6 months ago and it works like its fresh out of the box.

Comes on when you open door, and now it finally quit working


I think you've put up with enough hassle from this unit and should get another one. Intermittant flakey problems are hard (read expensive) to fix.
