Yes, There are fuses inside the keyboard panel. I would have to take a look at the manual for the specific model you have to identify the easiest way to check the fuse. Before you go that far check above the hood and see if you can locate the plug end of the microwave. Most installations have a dedicated receptacle above the exhaust vent and microwave. It is usually a space too small for good storage so most housewives store small items and cookbooks in this space. It is usually the culprit for a microwave suddenly going out without someone placing metal inside the oven and heating it. Heating a metal object or operating a microwave for an extended time will usually blow the fuse.
Yes, there is. If you go to searspartsdirect.com and type in your model number, you will find the fuse listed under the "Interior Parts" heading as item number 14 (part #815174). You can find appliance fuses much cheaper at the local hardware store. Just make sure it is the correct type and rating (refer to the fuse in the appliance for the information - these are usually a 120V 20A fuse). The reason I mention this site is because they provide excellent part drawings and provide part numbers. There should also be a wiring diagram located behind the control panel to assist you in troubleshooting. Please go to my profile and use the "Ask Me" feature if you require further assistance. I hope this helps you.
