Will it still work with the se or 5e error code?

Thank you for your post, friend!

I understand that your Frigidaire microwave is displaying the error code "SE" or "5E". I have researched and the error code seems to be "SE" which means keypad is stuck. In order to remove the error code the keypad would need to be replaced.

Regrettably, this is not a simple DIY job. I would highly recommend reaching out to an expert technician to ensure the appropriate replacement part is ordered and is installed correctly to prevent future issues. I hope this helps to some degree. -Matt
