The microwave stopped working on my Kitchenaid oven/microwave combo built-in unit. I suspect either the magnetron or transformer is shot. it made a strange and louder than usual noise during operation and then I there was a faint burning smell so turned it off. All works fine, full working digital display, turntable, lights, fan etc but it does not heat. Question is how do I access the magnetron & transformer components? Looks like I might be able to get to it from the front of the microwave since the front panel looks like it's removeable or does the entire unit have to be removed from the wall?

Thanks, I suspected as much but question remains, how do you access the electrical components in this microwave, does entire unit need to come out of the wall or can you get to them through the front face of the microwave which looks like it can be removed by taking out multiple screws?

Thanks
