This arrived this yesterday and waited the required 24 hours before setting it up. So excited to get this unit. All was working well with the hot and the cold, but the room temperature did not work. We read about troubleshooting and looked on the website and started the reboot. But, my hubby had noticed the room temperature button had no resistance. Removing two screws from the top we looked in to see that the button had not been installed correctly. He fixed it and voila, we have our water dispenser working. A bit disappointed that we had to fix a brand new product.
