Hello Unhappy, and thank you for contacting us. If you have not tried it, turn off switches on the back and unplug your machine (UNLESS YOU HAVE MODEL 601242 or 601264). While the machine is turned off, 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. Here is a video for further explanation: https://youtu.be/7ZKp3fOgkfo . If it does not fix it, we will need to look at other options. You can either email social@primowater.com or you will need to call customer service. Please be aware that call volume may be high, especially on Mondays and Fridays but there is a callback feature. Troubleshooting effectiveness is at its highest when it is over the phone, and the customer is at the machine. Since we are unable to call out, please call us at (844) 237-7466 Monday-Friday between the hours of 8am and 9pm EST to do further troubleshooting so that we may get your product back into working order. Please have the serial number and model number handy when you call. It is on the back of the machine.  If you decide to e-mail instead of call, please fill out the information below    Picture of the back of the unit:    Picture of original purchase receipt: Full Name:    Phone number:    Shipping address:    Model number:    Serial Number (10 digits on a white sticker on back of unit):    What brand of water do you drink?:    Is this your first dispenser purchase (any brand), what made you decide to purchase a dispenser if this is your first?:    Best regards, Michael P.
