re: Freezer temp alarms

The best tip I've seen is to put a penny or something in a water bottle and freeze it one way. Then turn the bottle the other way in the freezer. If your freezer ever de-thaws, you will know by looking at that bottle. It won't save your food, but it will save you from eating spoiled food.

I built a prototype with an arduino that would alert me if there was an issue, but I figured it would cost too much to make in mass.

I really wanted something that would email or text the repair company to a problem, as i waranty everything i touch for 6 months to a year and I like to stay on top of it.

The worst failure I ever had was a fisherman had us repair his freezer, and then in failed again two months later and Both I and my tech were out of town, so I could only offer to pay for the repair. He wanted reimbursement for spoiled food, but I don't do that. I felt horrible about it, still do. I get the most service requests the three to four weeks a year i take off.
