Not alarm. **Q: How long does it run on the potatoes?** A: We had it for about a week and it ran strong. The potatoes started to look bad so we threw the whole thing out. I imagine it would run the clock until the potato went completely bad. **Q: Followed directions about setting time, but didn't work. Any hints?** A: Here are the instructions for setting the clock. These are provided with the kit as well. SETTING THE CLOCK 1.
