When using Samsung oven NE58R9431SS/A, I was baking at 350 degrees F – i left the kitchen for a while and came back to find that the oven had switched on the broiler, even though oven was set to bake. The heat was about 600 degreesF and I couldn’t switch the oven off – I had to turn off house electricity to shut the oven down. This has now happed at least 6 times since October. This is a 3 year old oven and I contacted Samsung to report the fault and get the oven fixed. They have informed me that the part is not longer available and they would not be able to help – left high and dry and Samsung not taking this issue seriously!
