Australian Whitegoods Questions? Ask a Technician for Answers ASAP
Hi, welcome to Just Answer. My name is ***** ***** I look forward to helping you! If it sounds the same as it always has but does not heat, the magnetron is likely faulty. If it is much quieter, you may have a faulty control module or door switch. Growling or deep buzzing would likely be a faulty capacitor or rectifier diode. Does it sound any different?
