Whirlpool Microwave-Oven Combo

Hi, I hope someone can guide me on this repair. Part of the control micro-computer touch pad does not appear to work. The oven part works just fine but the microwave does not. My first thought was that perhaps the touch pad had gone bad so I ordered a new micro-computer control card. I installed it and its still the same; the microwave does not work. There are two fuses that I didn’t think to replace but will do so as the next step, one is easily accessible but the other one is not; this is where I need the help! How do I take the microwave front apart so that I can get inside the cabinet to replace the fuse (part # 27 - 4375321). I looked at the installation instructions but they don’t seem very clear and don’t want to take unnecessary components apart. Is there a repair manual or diagram that shows how to take it apart? Thanks for any help you can provide!
