As a home renovation expert who‘s tackled my fair share of freezer-to-fridge conversions, I‘ll share all my tips and tricks to make the process as smooth as possible. By the end, you‘ll be a pro at maximizing your freezer‘s storage and keeping food perfectly chilled. Sound cool? Let‘s get started!
Freezers vs. Fridges: What‘s the Difference?
Before we dive in, it helps to understand exactly what makes freezers and fridges distinct appliances.
The main differences come down to temperature, insulation, size and organization. Check out this handy comparison:
| Factor | Freezer | Refrigerator |
|---|---|---|
| Temperature | 0°F to 10°F | 34°F to 40°F |
| Insulation | Thick, tightly sealed | Thinner, more air exchange |
| Size | 10 cu ft or larger | Typically less than 10 cu ft |
| Organization | Chest or upright models | Shelves, drawers, door storage |
As you can see, freezers are made to maintain freezing temperatures for long-term food preservation. Fridges provide just enough cooling to keep food fresh for a few days.
Now let‘s look at how to modify a freezer to function more like an everyday refrigerator.
Installing a Temperature Controller
The most essential modification is installing a temperature controller. This device allows you to regulate the internal temperature of the freezer.
I recommend choosing a digital controller with an adjustable thermostat and temperature probe. This gives you precision in setting the ideal temperature range. Look for models that allow you to set temps between 30°F and 40°F.
Installation is straightforward – simply plug the freezer into the controller, then plug the controller into your wall outlet. Place the probe inside the freezer according to the manufacturer instructions. Use the buttons to set your desired temperature range.
The Johnson Controls Digital Thermostat Controller is a great option that provides accurate temp control for around $50.
Adjusting the Door Seal
Next, check the door seal on your freezer. You want it to close tightly with no gaps to prevent cold air leaks.
If the seal is worn, replace it with a new gasket designed for refrigerators. You can also use weatherstripping sealant tape in a pinch to fill any cracks or gaps if you don‘t want to replace the whole gasket.
Test the seal by closing a piece of paper in the door – if it pulls out easily, you need a tighter seal. Opening the door should provide noticeable resistance.
Allowing Time for Gradual Temperature Change
Be patient – converting a freezer into a fridge takes time! Once you install the controller, it could take 12 hours or more for the temperature inside to rise to the refrigerator range.
Start by setting the temperature to the warmest setting, around 45°F. Monitor the temp with a freezer thermometer, gradually lowering the setting over several days as it approaches 40°F.
While the freezer cools down, avoid loading it up with food just yet. The initial temperature fluctuation could lead to spoilage.
Smart Organization for Maximum Storage
Organization is key to maximizing your converted freezer‘s storage capabilities.
For chest freezers, use crates, baskets and storage bags to corral similar items. Place fruits, veggies and condiments in easy-access top containers.
In upright freezers, take advantage of existing shelves and slide-out baskets. Reserve bottom bins for heavy items like milk and juice and top shelves for snacks and lunches.
No matter the style, keep ingredients you use regularly within easy reach. And don’t overload shelves – allow space for air circulation.
Recommended Temperature Range
Once your freezer-turned-fridge holds steady in the 34°F to 40°F range, it’s ready for food storage.
Ideally, aim to keep it around 37°F to balance food safety and energy efficiency. Any warmer than 40°F runs the risk of potential spoilage.
Expect to see some moisture build up and frost, especially with frequent opening. Be diligent about monthly defrosting to control condensation.
Storing Different Types of Food
Wondering what foods do best in a converted freezer fridge? Here are my top tips:
Dairy Products
Butter, milk, yogurt, eggs and cheese should go on lower shelves where temperatures are coolest. Keep an eye on expiration dates – the longer storage may accelerate spoilage.
Fruits and Veggies
Leafy greens, berries and cut fruit fare best in high-humidity drawers or sealed containers. Storing carrots, citrus fruits and melons loose on middle shelves works well.
Fresh Meats
Raw steaks, chicken and pork require very cold temps – keep them in the coldest section or bottom basket. Resealable bags prevent freezer burn.
Frozen Foods
Pizzas, ice cream and frozen dinners store well in a converted freezer. Just don’t overpack – too much frozen food warms up the appliance.
Leftovers
Designate a shelf or bin just for leftovers. Keep them contained in reusable containers and labeled with dates. Use older ones first!
The Pros and Cons of Conversion
Like any DIY project, there are both advantages and drawbacks to consider:
Pros
- Massive storage space compared to normal refrigerators
- Ability to buy ingredients in bulk
- Longer freshness of fruits, veggies and meats
- More control over personalized meals and snacks
Cons
- Higher upfront cost for equipment like the temp controller
- Increased energy bills from running the larger appliance
- Manual defrosting requirements
- Noisy operation and compressor vibration
For many people, the extra capacity outweighs the cons. But be realistic about your needs before taking the plunge.
Energy Efficiency Considerations
Freezers require significant energy to maintain such low temperatures. When converted to a fridge, electricity costs inevitably rise.
Some ways to maximize efficiency:
-
Choose an ENERGY STAR-rated model manufactured within the past 5 years
-
Opt for an upright rather than chest freezer – they lose less cold air when opened
-
Use exterior insulation panels to reduce appliance workload
-
Keep door openings brief and food loads reasonable
Here‘s how estimated yearly energy costs compare for different models:
| Appliance | Kilowatt-hours Used | Estimated Yearly Cost |
|---|---|---|
| 10 cubic foot chest freezer | 472 kWh | $50 |
| 16 cubic foot upright freezer | 567 kWh | $60 |
| 20 cubic foot refrigerator | 307 kWh | $32 |
As shown, even the most efficient freezers use almost double the energy of fridges. Keep running costs in mind with your conversion.
Defrosting Your Converted Freezer
Moisture buildup and frost are unavoidable downsides of converting a freezer. Plan to defrost your DIY fridge every 4-6 weeks.
The process is simple:
- Unplug the appliance and remove all food.
- Prop open the door and allow frost to melt. Place towels nearby to catch drips.
- Once fully melted, wipe down the interior with clean cloths.
- Dry thoroughly before restarting the fridge.
Look out for signs you need to defrost, like failing seals, ice buildup and inaccurate temps. Don‘t let frost exceed 1⁄4 inch!
Chest Freezer vs. Upright: Which Is Better?
Wondering which type of freezer to convert? Here‘s how they compare:
Chest freezers offer more capacity for the footprint. The lid also helps cold air stay inside. But rummaging around in them can be a pain!
Upright freezers have shelves and slide-out baskets for organized storage. However, the door design loses more cold air when opened frequently.
I‘d recommend a chest freezer for garage or basement installations since ease of access isn‘t as crucial. Go for an upright if it will be your main kitchen refrigerator.
Recommended Freezer Models to Convert
If you‘re buying a new freezer for fridge conversion, look for these key features:
-
Size: 15-25 cubic foot capacity
-
Age: 5 years old or less for energy efficiency
-
Extras: Baskets, shelves and drawer slides for organization
Based on these criteria, here are my top recommended models:
1. GE Garage-Ready 7 cu ft Chest Freezer – compact and energy efficient
2. Frigidaire Gallery 17.1 cu ft Upright Freezer – lots of shelf space
3. LG Door-in-Door 24.7 cu ft Multi-Door Refrigerator and Freezer – convert side-by-side for massive capacity!
Check retailer sites for current pricing and availability. And don‘t hesitate to shop used and vintage freezers if they‘re in good shape.
Reversing Back to Freezer Use
What if you want to convert your freezer/fridge back to just a freezer? No problem!
Simply unplug the temperature controller and allow the appliance to gradually cool back down over 24 hours. Once it reaches sub-zero temps, it‘s ready for frozen storage again.
You may need to turn the dial down to max cold. Monitor interior temps with a thermometer before loading up on frozen goods.
And if the door seal needs replacing again, make sure to swap it out for one rated for freezer use.
Alternatives to Freezer Conversion
If converting a freezer fridge doesn‘t work with your space or needs, consider these alternatives:
-
Compact mini-fridges: Great for offices, dorms, pool cabanas or even game rooms! Opt for an adjustable thermostat model.
-
Beverage coolers: Designed to chill drinks, they also work for takeout leftovers, beauty products or other small items.
-
Additional refrigerator: Adding a secondary unit just for food and drinks can provide extra storage as needed.
-
Plug-in cooling unit: Aftermarket plug-in freezers offer fridge space without a permanent installation.
Any of these options can provide the extra cooling power you need – without the major project of converting a freezer.
The Bottom Line
Converting a freezer into extra refrigeration takes planning – but the massive storage capacity gains make it worthwhile for many households.
The process requires adding a temperature controller, sealing the door, monitoring conditions and organizing interiors wisely.
With the right prep and models, you can double your food and drink chilling abilities. Just be diligent with efficiency and cleaning to keep your converted freezer humming along happily!
