That's life. Replace the old one. You can purchase new Magnetrons.

Replacement magnetrons are usually priced between $60 and $120. New,
low end, commodity microwave ovens average about $160. A repair might
be worthwhile if the old oven is in good condition.

What I was doing for a while was salvaging old working microwave ovens
for the electronics and magnetron. The theory was that I might run
into the same model and could use the parts. In about 20 years, I've
replaced exactly one magnetron from my pile, and it blew up in about a
month. I recycled the pile a few years ago and currently use new
parts.
