Microwave Door Loud, Hard To Close, Starts as Soon as the Door Closes

If you find that your microwave door closes loudly or is harder to close than your previous model, the difference in the door noise is due to a firmer spring in the door latch; this is a normal condition for the microwave. You can lift up on the latch to feel the tension.

If the microwave starts as soon as the door is closed, the microwave isn't really starting; the fan is coming on in anticipation of the unit starting. Try shutting the door firmly three times to avoid the fan sound in future use.
