Review: Simple, but effective and reliable - Got this fridge door opening alarm about a month ago and it has already caught the freezer door not fully closing twice. Installed it on a garage freezer; setup was very easy and the adhesive has held well so far. The alarm is audible from inside the house—faint but noticeable at the highest setting, similar to a car alarm going off outside.
Review: Gets the job done - I purchased this door alarm because my children kept leaving our stand-up freezer open repeatedly causing us to lose the food inside. It was easy to install, just had to add the stickers. And the settings were simple. It begins beeping when the freezer door is opened for one minute and I set the volume the loudest it can go so we can hear it from outside the room it is in.

## Questions & Answers

**Q: Why does the alarm go off when the door is closed or randomly?**
A: This is most likely due to installation issues. Please make sure the small triangles on the alarm (the larger piece) and the magnet are aligned and placed as close together as possible. Avoid rapidly opening and closing the freezer within 1 second.

**Q: Will it work if my refrigerator has a large gap?**
A: The distance between the alarm and the magnet should be ≤ 1.38 inches on non-metallic surfaces and ≤ 0.98 inches on metallic surfaces. If your refrigerator has a large gap, you can install part of the alarm suspended (our adhesive tape are strong).

**Q: Will it work if there’s a height difference between my refrigerator door and the main body?**
A: Yes. Simply install the alarm on the higher side and raise the magnet using something like modeling clay for proper alignment.

**Q: Will it work if my refrigerator is close to the wall with a small gap?**
A: You can install the magnet in the gap (magnet size: 0.47 × 0.5 × 1.8 inches), and place the alarm in a more spacious area. It can also be installed at the top of the refrigerator door or in other discreet locations.

### ⭐⭐⭐⭐⭐ Great Freezer alarm. LOUD!
*by A***A on April 10, 2026*

After loosing a upright freezer full of meat due to the door not fully closing, I was looking for something to alert us to if this happened again. This alarm functions the way I would expect. Install was quick and easy. The alarm is LOUD! We have it set at one minute - I would suggest maybe 2 or more. When looking in the freezer for something takes a bit longer than you expect, the alarm will definitely get your attention! UPDATE: after having it for about 8 months, it's still been great. The alarm has started going off here and there after we get into the freezer (but the door is fully closed). Wondering if we need to adjust them to be closer. Still very happy with this purchase!
