Popcorn button on microwave oven. How does it work?

This is how ours works and it screws me up now that most brands have reduced from the 3.5 oz bags.

I would think that 1.75 minutes is 1:45 not 2:15. It is not 1 minute and 75 seconds.

You must be from one of those foreign countries where they use metric time.

No, just someone who thinks number separated by a colon means something different than numbers separated by a decimal.

You may be right – certainly, your reading is more sensible – but how would that count down?

What does the display read after you push the Start?

How does it work? Oh pretty good! But it is actually a timer, not magic or humidity levels or other mystical things.

Scale? Are you suggesting that popped corn weighs less or more than unpopped corn?

I think it’s more a matter of a heavier bag requiring more time than a lighter one. My microwave certainly does not have a scale, though, as certain defrost settings require me to input the weight of the product.

The 1.75 refers to the size of the bag in ounces. That is for snack-size bags. I bet if you push the button twice, you’ll get the other common size, 3.5 oz.

I just looked up a Sharp Sensor microwave manual, and it specifically says for the sensor it uses the vapor from popcorn bags to gauge cooking time. It also says specifically to use only made-for-microwave popcorn bags for the sensor to work properly.

my previous microwave could be set for 1 minute, 75 seconds. I’m not sure about the current one (I mostly use the sensor setting), but on the old one, pressing 1-7-5 would get you 1 minute, 75 seconds of heating.

I realize that if it were a programmed timer, it wouldn’t do that (and like the weight suggestion down thread), but it’s not an impossibility.

Read an article just the other day about some company developing a microwave with an audio sensor that could get popcorn right every time, for any size bag (pop is distinct from normal hum/fan noise).

For the 1.75 tangent: On my microwave, pressing the popcorn button once produces 1.75, a second press produces 2.5 . This was NOT the actual time it ran for, rather it seems to refer to the size of the bag (in ounces, maybe?).

More than anyone could want to know about the ‘popcorn button’!
