When I connected my microwave oven to a voltage stabilizer which is being used for refrigerator,the microwave oven motor starts working without any functions provided.The motor keeps on rotating at lower rpm. What could be the reason behind this?

    Perhaps your "voltage stabilizer" doesn't output sinusoidal voltage and this produces harmonics which upset the oven's sensors. – RedGrittyBrick Aug 23 '13 at 19:39

    Does the microwave really need to be connected to the stabilizer? I can understand why a refrigerator would need it, but not a microwave. – wallyk Aug 23 '13 at 20:39
  • I agree with redgritybrick+. A micro wave has sensitive electronics by its basic design, many refrigerators are very simple motor driven compressors with some lights and fans I would say the microwave would benefit more than a fridge, in fact a fridge creates surges and dips when the motor starts & stops. – Ed Beal Mar 9 '18 at 19:00

    I think the obvious but un-answers question is, have you tested the microwave without the stabiliser since you noticed the problem? – Notts90 is off to codidact.org Nov 11 '18 at 8:03
  • So just the turntable is going? – rogerdpack Dec 14 '18 at 5:37

You should / MUST not connect stabilizer made for refrigerator to microwave oven. Stabilizer for fridge will be of capacity around 0.5kw and that for microwave oven should be around 2kw or more.

  • It depends on the size of the stabilizer without that information you really can't say you must not. – Ed Beal Mar 9 '18 at 18:50
