Robert,
Yes of course! e.g. For entered 1 minute, timer expects 60, (3600 cycles),
Second Ticks but on 50 Hz power receives only 50. Therefore cooks for
another 10 ticks which takes 1/5 minute longer.
Thank you for the correction.
Tony,

If the frequency rating of the product is 50-60 Hz, it should be OK.
However, if the rating is only 60 Hz, there may be the
following frequency
sensitive concerns:
* Lower output from transformers due to insufficient core size
* Slower speed fans
Ravinder,
Yes, been there, done that! (Kenmore 1980's Model).
Used a 2kVA xformer w/ US style outlet strip for microwave and other US kitchen
appliances. Only problem - Clock/Timer ran at 5/6 time so it was necessary to
enter 1:12 for every 1 minute of cook time! (Perhaps some up to date models

Hi Ravinder,
I have read the other replies that advise to check the voltage and frequency
rating of the microwave's power supply. They also warn of the effects of
changing power frequencies.All good advice.
I have another concern to add.

Hi Ravinder:
I am interested in knowing if a 120V, 60Hz microwave oven can be safely
used on a 240V, 50Hz mains supply with a step-down transformer.
In essence, you are asking if a microwave oven
rated for 60 Hz will operate safely at 50 Hz.
I would guess that the microwave oven uses
