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, --Reply

: RE: 120V appliance on 240V supply 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. Remember the recent thread about single phase,

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
