Works great except loud buzzing
So so thought it was the diode replaced that.
It still heats food and water 1 cup in 60 seconds to boiling.
What's my next move ?
It's heating, so magnetron isn't the problem right?
Buzzing is constant soon as you start cook cycle starts within 3 seconds of pressing start.
Prior to this constant buzz it was only happening when magnetron was firing.
could tell because you'd see food or water boil when buzz was there .
For example during a 4 minute or longer cook cycle. A year ago it would not begin buzzing within seconds of pressing start. It would only buzz when magnetron was hearing.
