Hi have this 15 year old Amana microwave that, as of late, appears to
run its magnetron continuously for the entire cook time. Where should
I begin looking? How is the cycling of the magnetron controlled?

Hi,

No model# posted....but most microwaves use a relay to cycle the power
off and on for the different cooking powers.
Some older units use a triac switch controlled by the board to cycle
the power levels.
