F7 means that the control panel is not getting feedback from the Switched Mode Power Supply (high-voltage inverter).

This could be due to a problem with the inverter or the control unit / circuit board, but it appears to be the latter in most cases.

We repair microwave control boards for customers nationwide with our guaranteed $39.95 service.

We have full details, plus critical safety, disassembly, and troubleshooting info at our site. You'll find a link to our site in our listing here on FixYa: http://tinyurl.com/yzjozk

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful.

You may reply back with your brand and model number if you'd like us to look into this further, or feel free to contact me directly if you need more help.

We're happy to help and we appreciate your thoughtful rating of our answer.

The F2 error code on your microwave oven is a membrane failure.
It is recommended that you replace the membrane first & if you still have problems to replace the control board.

There is a mini-manual inside the oven which can aid in troubleshooting.

 

If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info (as well as a text file which helps in diagnosing and repairing door switch problems) at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk

4. Check all Cavity Thermostats for closed circuit.

NOTES ON INVERTERS

 

This model uses an inverter to produce high voltage instead of a convential transformer system.

 

While an inverter (switched-mode power supply) is more efficient from a power consumption standpoint, it is more complex, thus more statistically prone to fail. These should only be examined and worked on by someone who has the necessary technical qualifications. Seriously.

 

Often the machine-soldered connections in a microwave inverter are too weak, so they eventually fail, especially if heat is high in the area. They sometimes fail catastrophically. When not catastrophically damaged, you may hear clicking or squealing and may smell an electrical odor, which is sometimes obscured by the cooling fan.

 

Some manufacturers do not encourage or assist technicians to repair microwave inverters. Most offer the inverter as a whole assembly. But sometimes that is actually cheaper than the time and labor required to fix the old one.

 

If a technician is willing and able to troubleshoot and repair the inverter to component level, it will may be expensive, but may be worth it, especially if he or she will resolder and reinforce connections as needed as part of a thorough repair. That could easily make your inverter beter than a new one!

 

You might be able to get some verbal estimates if you call Panasonic-authorized repair shops and ask then specifically about inverter repair and inverter replacement costs for your model number.
