If it's not addressed in your owner's manual, you will need to take the cover off the oven to find and replace it.

The owner's manual will also give you contact information for your manufacturer so you can contact them to find local or nearby parts distributors.

You can find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.

all makes & models are fairly basic but some have 1 fuse inside the unit & some may have 2 or 3. mine had 2, one for the fan & one for the microwave functions control board. they are usually see through fuses so it's easy to tell if they're blown.you have to remove the microvave metal casing to get to them. hope this helps.

press the clear button. then try the number pads. if no response, then more than likely you got ripped off. samsung microwaves have very high keypad failure rates.

Hi, if the fan, evaporator fan is not running, it has failed on you. If you are up to doing this kind of work, you can replace it your self. It is a 120 volt evaporator fan motor, and if you can get it out, take it with you along with the name of the unit, model & serial # to an appliance parts house to get one. If they don't have the exact one, they have universal ones that will fit. This will solve your problem.

You can set it to different levels. It is doubtfull the magnetron will deliver more than 750 Watts as that is about all they can produce singley. Commercial ovens use at least two magnetrons.
Most specs on microwave ovens quote the power drawn not power produced.
I hope that helps.
