    Freezer Alarms Buying Guide

    A freezer alarm is an essential device for people who want to ensure that their food stays frozen. However, it can be hard to know what kind of alarm you need and how much it should cost. And if you’re going to invest in finding the best freezer alarm, it’s worth investing in the right one; not just any old model will do. This guide will help you find your perfect match!

    Things you need to consider when choosing the best freezer alarm:


    The price of a freezer alarm varies widely, which is why it’s important to know what you need. Of course, it may be tempting to look at the most expensive model on the market. Still, your budget will ultimately determine what you buy.

    Noise Level

    The noise a freezer makes is another thing worth considering. If you’re not going to be home when your food starts defrosting, it’s important that the alarm can get someone’s attention, even if they are far away from the kitchen.

    Suppose you intend to use your freezer alarm to alert you in an emergency. In that case, it’s worth investing a little more money so that the sound of the notice is louder and travels farther. This will ensure that your family or pets can be alerted before your food does! It may also be worth buying one with 2 alarms so that you and your partner can be alerted if one alarm stops working correctly at any time.

    Battery or Power Cord Options

    Some freezer alarms run off of batteries, but others need to be plugged into the wall. Whichever option you choose should fit in with your other priorities.

    Size & Style

    The size and style of your alarm are pretty subjective. First, consider what your kitchen is like so you don’t choose an alarm that fits your home’s look and feels.

    Food Safe Materials

    Though the materials your freezer alarm are made of will hardly matter after an hour or two if you have a power cut, it’s still worth paying attention to. Choose something that won’t leech chemicals into your food!

    Type of alarm

    There are two main kinds of alarms that you can choose from:

    1. Freezer thermometer – This is a type of alarm that uses a probe to monitor the temperature of your freezer and will alert you if it drops too low. There are many pros and cons to this option, one being that they aren’t very accurate. Still, another being that they are incredibly easy to install.

    2. Manual alarm – This kind of freezer alarm is pretty self-explanatory; you just press down on the top for it to sound the alarm. They don’t require any installation and can be bought in kits with other food items like a safety timer!


    Is there a warranty?

    Make sure you check the fine print before you buy your alarm. This way, if it malfunctions within a few months of buying it, you can contact the company and ask for a refund or replacement!

    What are the benefits of using a freezer alarm?

    A freezer alarm can be a very useful item to have in your kitchen. It can help you protect your frozen food and alert you if there is an electrical or mechanical problem with your freezer.

    How do I install my freezer alarm?

    Most alarms are quite easy to install; all that’s required is for you to punch some holes in the top or sides of your freezer and then slide the alarm into place. If you can handle a screwdriver, this shouldn’t be too hard for you!

    How much do they cost?

    Freezer alarms vary widely in price, with some cost more (and others less!) than others. However, most of these devices are a reasonable price.

    What temp should I set my freezer alarm?

    The best temp to set your freezer alarm at will vary, depending on the kind of food you have in it. You should also always check the temperature yourself by using a thermometer!

    What should I do if my alarm goes off while I’m out?

    Call someone close to your house and ask them to check in on your freezer if this happens. It may be that it isn’t as full of food as you thought, or that you have a power cut. Another option is to go for a smart alarm where you can check the device through your smart phone.

    Can you keep a deep freezer in the garage?

    If you have a deep freezer or want an outdoor one for some reason, yes! Freezers are rated to be used both inside and out. Your freezer should be fine as long as it is covered and kept in a dry spot out of the elements.
