Hello. I have a less then 3 year old above the range microwave that all of
a sudden wont heat up. No flashes or pops, it just stopped heating up.
Everything else works, turns on, all the buttons, lights and fan. I noticed
that although my warranty was only one year that the magnetron tube is under
warranty for 8 years. Would the magnetron tube cause it not to heat up? Im
not really sure where to start with this so I thought I would start here.
Thanks for any help.

If the magnetron fails, it will not heat.

Could be the magnetron, but there can be a dozen other reasons too, even a
faulty keypad.

The most common problem I have run into while using microwaves for the past
30 years has been a blown fuse inside the cabinet. Easy and cheap to
replace. I keep a few spares taped to a corner inside the cabinet. Next is a
defective microswitch on the door, often there are two in series as a safety
to prevent operation while the door is not latched. Little bit more
difficult to obtain and a little bit more difficult to diagnose and replace.
But doable.

Yes, a bad magnetron is one possible reason why your oven isn't heating.
However, there are numerous other reasons that could cause this as well. It
could also be a bad high voltage capacitor, bad diode, faulty door
switches, faulty control panel, burned wire, etc. Magnetrons "usually" hum
when they go bad, but not always. Microwaves store dangerous voltages even
when unplugged, so they're not really a fix-it-yourself item, even if you
can find a source for the parts. It's probably cheaper and easier to
recycle the old oven and buy a new one.
