Hello, Thank you for using this service, I will be helping you with your problem today
there is an internal fuse inside behind the control panel on the Noise Filter you can purchase the fuse at lowe's , bring the old one with you.
Am I replacing the whole card pictured, or just taking the fuse out from the clip in the upper right hand part of the pictured card?
Well, fuse replacement isn't the answer. The microwave does not power up. What's next on the troubleshooting list? I'm thinking it gets a lot more expensive from here.
I'm sorry to hear that.there are other things that can cause this but the whole machine has to come apart. theres a thermal fuse that may have blown. # XXXXX on this diagram other than that its the control board.
