Whats wrong with our microwave?

Question

it makes weird "eerrrrrriing" sounds (if that makes sense) but it still works

it sounds like a kind of dull roar

Answer 1

isn't it suposted to make that sound

mine does that and it works Great!

Answer 2

Not much to work with but, could it be the fan or turntable motor?

Answer 3

Could be any one of a number of things if it has moving parts like a revolving plate in the bottom, or an energy distributing fan.

Answer 4

It sounds like the fan blades are just hitting against something while spinning. I would say open it up and fix it, but it can be dangerous if you don't know what you're doing.

Answer 5

It has a fan in it and the bearings may be worn out. Not sure without hearing it live.

Answer 6

problem with magnetron
