A:Answer Bottom loader dispensers do not have a room adjustment. If you have not tried it, turn off switches on the back and unplug your machine. While the machine is turned off and unplugged, dispense about 4 cups of water from the cold dispenser. Then, plug the machine back on and turn on only the green switch. Allow one hour for the unit to cool the water before checking the temperature. If this does not work, please call us at (844) 237-7466 Monday-Friday between the hours of 10 am and 6 pm EST.
