Fridge Door Alarm with Delay, 60sec, 120sec, 180sec Reminders, Low/Loud 80dB to 110dB, Freezer Door Chime when Left Open – Compact Size. (Black)

After yet another freezer-not-being-properly-closed-by-returning-offspring-after-a-nightout, we got this device. I had previously had a more expensive wireless temperature monitor for the same purpose, that was really designed for professional settings like labs etc. It had 2 sensors you just put in the freezer/fridge and then a receiver/alarm unit located within range. But I found it went off occasionally for random temp fluctuations not actually caused by the door being left open, and was then fiddly to reset. Anyway I made the mistake of thinking 'those days are over now the kids are older/more responsible....' - well, you know how that one ends. A week ago we lost another load of frozen food after an all-night door slightly ajar situation which caused the tempertaure to rise so much, we had to defrost the freezer completely and start it again (BTW top tip - last time this happened, we thought something had gone wrong as it simply wouldn't reach freeze temperatures again. Paid £250 for a Miele callout to be told 'defrost it completely, then turn it on again, and leave it for 12 hours'. So that's what we did this time, without paying for the advice - works perfectly). So now I've replaced my old temperature sensor with this distance monitor. So - as for installation - this is the tricky part, and of course it all depends on how your freezer is located and whether it's built in or not. So ours is built in and I decided the neatest solution would be to position the device on the underside of the door - see pic. The main unit went on fine - luckily there was a 4cm gap between the back edge of the door of the freezer, and the vertical panel between the door bottom and the floor. The sticky pad for the main unit worked fine also - very sticky and am confident it will stay on for a while, despite being at maximum risk (ie with gravity applying constant pressure and in an area exponse to damp/cold). That said, I only needed to apply it once - see below. The instructions were that kind of non-English, minimal type you get from, presumably, Far East manufacturers, but it's fairly easy to work out that the different volumes of alarm are activated by 1, 2, 3 or 4 presses of the 'set' button. The next bit was the hardest part. I wanted to position the smaller 'activator' unit so that even if the door was only slightly ajar, it would go off. So here's what I found: 1. The alarm triggering depends not only on how close the units are to each other in terms of the gap between them side-by-side, but also 'vertically'. So you can see from the pic how I ended up with the smaller unit moved towards the 'top' of the main unit. I found this to be the exact right spot for triggering even a slight gap (say, 1cm or less) of the door being ajar. This is crucial for us as it only takes this kind of gap, left open all night, for the freezer to get upset. 2. The sticky pad for the smaller unit stopped working after 3-4 efforts to get the positioning just right - presumably because I was sticking and unsticking it to a slightly greasy, cold, aluminium surface. Cleaning the surface didn't help, so I gave up on the pad. I took it off from the unit and instead improvised with insulating tape and UHU glue. I also marked the final location with a Sharpie, as you can see in the pic, for good measure, in case it gets knocked off. 3. My wife is very sensitive to noise, but we also need the alarm on the loudest setting, so we can hear it when we're in bed late at night, as that's when certain people seem to visit the freezer carelessly. So it will be interesting to see what happens if we are opening the freezer to load/unload and the louder alarm is triggered (think this is 2 or 3 minutes, but again neither the instructions or the page here is particularly clear on this point). However - I can confirm - it's very loud and you should be able to hear it anywhere. 4. Finally, just to note, to replace the batteries you apply a bit of pressure to the front of the main unit and push it 'upwards' (towards the logo end), and the cover should just slip off. I can do this even when its located under the door like this - not difficult. Hope that's all helpful! Will repost an update if it goes wrong/doesn't last long. 2026 update: Don’t know if anyone is still reading a 2021 review of a fridge alarm but suffice to say, 5 years later, I’ve just bought another one for our new house! Indispensable - even for brand new fridges with a supposed alarm system. Don’t know why but for some reason they just don’t seem to work if you leave the door slightly ajar. This one always does!

Great little alarm for the freezer. Freezer is in the outhouse and can be heard from there into our house. Easy to set up and works very well.

After having spoiled food due to leaving door slightly open we ordered this alarm. It was a little fiddly to fit but followed instructions and it is on our upright freezer door. It is a good reminder once we open the freezer and the alarm if we forget to shut it properly if good and loud. Definitely good value, if it saves one freezer full of food we’re in pocket. Unobtrusive on freezer as fits on the side, also we matched the colour to the appliance as there is a choice

Brilliant item, my Dad has Alzheimer's & now the fridge alarms to remind him to close the fridge!!!

Excellent product bought for my mum who kept leaving her freezer door slightly open, this works really well, easy to put on. Great value.

Bought this for a Beko Fridge freezer after leaving freezer door open all night in the basement! It is smaller than I thought, not obtrusive. Instructions were clear, but best to read them in conjunction with the video, which you can access via QR code in leaflet. We didn’t have any problems fixing it, we cleaned the area on the door first then lined it up as instructed. There are two parts, one for the door and one for the body of the fridge/freezer and they are only about 0.5 inches apart. You can test it before fixing it permanently. You can also set the loudness of the alarm. As ours is in the basement we have it on the loudest setting and we can hear it clearly from upstairs.

Works great if you leave the door wide open, but useless if you only leave it open a few mm! So this was NOT fit for my purpose! If your fridge/freezer door keeps getting left open about 5mm. This thing is no good for you because it is only sensitive to about 1.3cm. I moved the receiver away from sensor 1mm every 5 seconds. I got to 4.5cm away when it started beeping. So at 4.4cm no alarm and 1 mm later it alarmed. So I should have been able to move it back 1mm for it to stop beeping. But no. I had to move it back to 3.3cm before it stopped again! Even placing the thing at an angle would not get it to work the way I needed. Ie. The door open a very slight amount!

Great little device, a lot smaller than I expected, but does the job. I like the fact it makes a little bleep when you first open the fridge door, it's a good reminder that it is still working. It can be slightly fiddly to get the spacing correct at first, but once setup, it works well. Much better than other solutions I've tried.

accurate with even a slight gap in the refrigerator door, very happy with the product,

Une fois qu’on prend le temps d’attendre les minutes indiquées dans le mode d’emploi, c’est très efficace

Works way better than I expected. You can adjust when it triggers by just moving the magnet side back a bit. The alarm is very reliable which has brought less spoiled food from my fridge that likes to pop open when I close either side of it with just a little force. The installation is super easy with two sets of adhesive pads that are very strong. Should you need more you can use 3M mounting tape. This is loud enough to hear from 3 rooms away and very accurate on when it's misaligned after you calibrate it well. The connection between the receiver and the magnet is perfect and works extremely well. Highly recommend this!

I have a habit of not closing the basement freezer door properly, which resulted in spoiled food more often than I want to admit. I first tried putting a magnetic thermometer by the door and setting a temperature alarm, but this has two drawbacks. First, the alarm won't sound until the temperature inside has already reached a dangerous point, and even worse... the alarm wasn't loud enough to hear even one floor up from the basement. This alarm solves both those issues. If you are careful about placing the alarm and the magnet it will detect of door gap of as little as 1/8". If the door is that close to closed the door seal magnet should pull it the rest of the way in. Even more important than that though is the volume of this alarm is LOUD! As soon as you open the door you hear a quiet "chirp" which repeats every 20 seconds or so for the first minute, then it starts to beep louder and longer for the next couple of minutes to remind you to close the door when you are done. If the door remains open past four minutes the full siren goes off and I wouldn't be surprised if the neighbours could hear it. If you need to door open longer than four minutes, say for defrosting, there is a small switch on the alarm portion to turn it off. You can choose several locations around the door to mount the alarm and magnet and it comes with adhesive shims to equalize the door and body surfaces if they aren't exactly aligned. The handle side of my freezer door is only about an inch from the wall so I chose to mount the alarm and magnet on top of the freezer and door instead of the side.

Bon produit. Fait sont taf, il suffit tout simplement de bien l'installer.
