This is a french door refrigerator and has a feature that allows pre-setting water volumes from the dispenser. This feature has worked with no problem until recently. We moved to a new home in the same neighborhood and connected to the water supply per the user manual. When we try to set a pre-measured amount (e.g.-1 cup), this unit now delivers almost twice that amount. I cannot locate any info on calibration for this unit nor any info on which part (electronic board?) controls this measurement function. Manual delivery of water is no problem...just the pre-set measurement. Has anyone had experience with this issue?
