Question about Microwave Ovens
Mine did the same thing, I took the faceplate off plugged it back in and it works. The plug in was loose between the faceplate and board.

SOURCE: Some buttons work, some don't.
The keypad may be bad. Most often they go bad due to moisture from cleaners being sprayed directly on them or steam from the cooktop when the vent fan is not used.
They can also go bad when the unit is stored in an unheated environment where there's a lot of air temperature change (hot during the day, cold at night, etc.)
It may also be some residue on the connections where the keypad plugs into the control board. Unplugging then replugging the keypad can sometimes clean them.
In other cases, a new keypad is needed.

They have that manual their site, but it's only in French!
If you don't speak French, then visit the manual download page and put in only "SM807" in the search box.
The manual for either the SM80703 or SM80704 may be close enough to yours to work.

There are two options here:
1. Order a new control panel frame which has the keypad, trim piece and door button already installed and swap your control boards into it.
The original part number FPNLCB346MRK0 has been replaced by part # FPNLCB346MRK0B and it runs $58.28 plus shipping.
2. Disassemble your control panel frame, peel off the old keypad and stick a new one on.
Even though the keypad alone runs only $35.66, this job takes a lot of time and labor.
If you (or someone you know) might want to replace just the keypad yourself, I have uploaded a handy guide with pictures showing you what's typically involved.
Whichever option you choose, we have the service manual for this model and have uploaded it to our site here to help you.

When I opened up the microwave cover, noticed that the door latch mechanism was worn and not holding up the interlock switch. A thick piece of tape on the worn piece of plastic and microwave was back to working (I had symptom of the timer counting down without the microwave turning on)
