Guide :Microwave Ovens : NN-T993SF Microwave Oven
Microwave shutsdown after 24 seconds, does not heat up
The microwave starts up and the turntables turns for just over twenty seconds, but then just stops. The food does not feel any warmer. The power remains on. There are no unusual sounds or smells. I thought perhaps the exhaust vents were covered and the microwave was shutting itself down to prevent overheating, but I cleared any possible obstructions and the problem still persists. The unit is just over two years old.
