Brand new out of the box whirlpool microwave - WMC50522HZ - emits a loud buzzing sound at the start of heating. We got this new one because the magnetron on our old microwave was going, and it sounded almost exactly like this sound! Audio attached. Any ideas - do I take this back, since I’ve had it literally 3 days? Not excited about paying for a service call or for shipping & insurance you send it to whirlpool.
Or is this sound normal?
Thanks!

Take it back to the store and they will exchange it for you.
