Question about Microwave Ovens
Oven makes thumping sound when in operation
Is it a rhythmic thumping, or intermittent, or one thump when it first starts?
If it's rhythmic, it may be a failing turntable motor or stirrer.
If it's a thump just when you hit Start or when the magnetron turns on at the beginning of the cook cycle, it may just be a common noise that they sometimes make due to the magnetic field produced by the high voltage transformer.
