Water Cooler
Question
We have a water cooler (dispenser) that has hot, cold and power LED lights. When the temperature of the water falls below 90 degrees the Hot 'red' LED light will come on, when the temperatures rises above a certain degree, the cold 'green' LED light will come on. Is this a problem on Shabbat/Yom Tov?
