Question about Samsung SMH7178STD Microwave Oven
When pressing some of the sensor cooking buttons like "bevarage" the
oven starts working but after 3-4 seconds it stops, displaying "E 4".
What could I do?
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:
