Query: Product is Defective

This is the second one we bought - stupid us. The first one has a little screen on the controller. After a few uses it shows F1 on the screen. Sometimes it works for 2 minutes, sometimes for half an hour. I contacted Sunbeam, and they told me to plug it into a different outlet. Tried this, same result. Bought second one because it has different controller. Worked 10 minutes on low, then just showed blinking red light at high setting. Replugging does not help. These really are pieces of junk.
