Whirlpool code F1E5

The Microwave is between 1-2 years old. It just started giving a F1E5 code. It runs for about 10 seconds total before giving the code, after about three seconds makes a click noise.

I purchased a new inverter part #AP5645075 but this did not fix the problem. Any suggestions on what I should try next?

Thank you,

Jonathan

I replaced the magnetron and it’s working now. The old magnetron has a burned hole in the end that should not be there.
