Sharp had "issues" with that board (connector cable fail). That was back in 2002. Give them a call and see if they will send you a new control board (part # CPWBF070MRU0) All of the 0's are zeros.
If not, look at that ribbon connector where it's kinked, and you'll see a spot that should be repaired, ie broken wire.

Good luck with the phone call. Refer them to bulletin # MW-166.

This is usually caused by either a bad bottom door switch or a loose bottom door switch mount, which are pretty simple problems to fix.

Even though a door switch clicks, it may still be bad inside.

Door switch or mount trouble is usually caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

If the switch mount is broken, it's usually more economical and safer to add a dab or two of hot glue to the mount to secure the switch. Let it cool for about 30 minutes before using.

you have a bad spring and micro limit switch. You need to pull the cover in the front in order to remove that.

This may not solve your problem, but on my Sharp R315J microwave, the little plastic pin that pushes forward on the inside of the start button, had broken off and it wouldn't start. The Minute Plus button would start the microwave, so I knew the microwave worked, so I tried to find a piece of plastic that I could glue into the start button hole, because the part doesn't exist and you have to buy the whole door for $100 plus shipping. Nothing I could find was small enough, so I started looking for a new microwave.
While ouside doing lawn work I noticed a small bird tail feather and the end looked to be the perfect size. I snipped off the pointed end and then up about 3/8" to make a little rod to replace the plastic one that broke. It fit perfectly!!! I didn't even have to glue the inside end, it stays put even after repeated door opens. This is sturdy material and looks to last a long time. When it wears out, I have a cat, there's always a few feathers around. I hope this saves someone else a hundred bucks, like it did me.

My husband took the cover off and positioned the broken button where it will still push on the left corner. I dont know if we can buy just the button or what.

I would first suggest that you be sure every single wire got reconnected where it belongs.
