Defective Timer

I purchased this slow cooker about two months ago. Previously, I had a Rival Slow Cooker that used to burn the food (found out through reviews of that product that mine was a common complaint). This slow cooker attracted me because it had a programmable timer, and the option to use the temp probe to avoid overcooking the meat. Using this model with the temp probe has gone really well and I have no complaints about that. The problem occurs when using the timer function. Instead of switching to warm when the programmed time is reached, the slow cooker instead switches off. Then when I get back home, the food is cold and not safe to eat. I know that after 14 hours, it is supposed to shut off, but I am only gone for no more than 9 hours. Hamilton Beach is supposed to send me a replacement soon, so we'll see how fast their turnaround is and whether or not the new model has the same issues.
