AC Mains frequency and microwave oven

  1. Nov 25, 2015 #1
    Does the frequency of the main affect the performance of a microwave oven?
    Having moved from Europe 50 Hz to the Philippines 60 Hz I can not operate my microwave oven!
    Is that the reason? How to remediate?
    Best regards.

    Welcome to the PF.

    That would depend on the oven. What does it say on the back of the oven? There will be a label there with input power requirements. Europe is 50Hz 230Vrms, right? What is the AC Mains voltage in the Philippines? :smile:

    BTW, trying to run a 60Hz appliance on 50Hz can present an overheating hazard, so please don't try it again until this is figured out.

    He is going the other direction.

    Yep, and he says the oven doesn't work at all.
    (which I find a bit surprising - unless it caused the mains plug to blow it's fuse maybe)

    Oops, good point. Well forget about the overheating issue then... o0)

    I think microwave ovens are triac controlled and synchronized to the mains, but I don't know how and whether changing the mains frequency will affect operation.
    Could vary from oven to oven.
    I'm assuming Europe and Philippines are both 230V

    Also, the turntable motor is a 50Hz induction motor so it may turn faster or stall.

    What are the symptoms? Is it just DOA, or does it do something, but incorrectly?
