Magnetic screwdriver with extended shaft. If you have chewed the screws get a screw removal bit and use a torque driver.

I am having the same problem. According to the owner's repair guide error Code F7 indicates that power to the magnetron was interrupted. You will want to make the following checks: 1. Unplug microwave oven or disconnect power. 2. After 40 seconds, check to see whether this solves the problem. 3. Unplug microwave oven or disconnect power. 4. Check resistance of the magnetron thermostat. 5. Check the magnetron. 6. Check wiring to the 1100W inverter and control system. See "Checking Inverters." 7. Plug in microwave oven or reconnect power. 8. Check operation of all interlock switches. Check door, hinge and cavity front alignment. Adjust as needed. 9. Unplug microwave oven or disconnect power. 10. If switches operate correctly, replace 1100W inverter. 11. If problem persists, replace electronic control. 12. Plug in microwave oven or reconnect power. While this is helpful, it is still out of my confort zone as I pulled the control panel and discovered a virtual zoo of connectors. Obviously ponly a trained repairman knows which ones need to be checked. I will probably have to resort to calling one and shelling out the dough.

This sounds like the magnetron has failed, the pop sound is a classic sysmptom.

Hello & Welcome to FixYa

Check this image for your Microwave parts, part#25 and part#29 are two thermal fuse. If both of them are fine then it is the electronic control that is bad and needs replacement. Please get back to me if you have any other questions.
