The first thing to try is a "hard reset". Unplug it from the power line for a few minutes, plug it back in, set the clock, then try again. Let us know if the hard reset doesn't fix it.
If not, then you may have a problem is on the control panel, which we repair nationwide for $39.95 postpaid.

Microwave will not operate (cook). F7 error code
appears on the display.

the microwave inverter circuit.
1. Check door, hinge and cavity front alignment and adjust
2. Check the operation of all interlock switches.
3. Check over temperature protector for the magnatron.
4. Check all Cavity Thermostats for closed circuit.

7. If interlock switches operate correctly, replace 1100W
