Learn how to keep your refrigerator running efficiently with simple maintenance and care tips from Master Appliance Technicians.
Your refrigerator is the undisputed MVP of your kitchen, running 24 hours a day to keep your food fresh and safe. Because it works so quietly behind the scenes, many homeowners don’t think about maintenance until it’s too late. This is why implementing even one proactive refrigerator care tip can save you from an unexpected and costly repair bill. When a fridge breaks down, it’s not just an inconvenience; it’s a stressful race against time to save hundreds of dollars in groceries.
Since 2005, Appliance EMT has been helping homeowners maintain, install, and repair major appliances. To help you avoid unexpected breakdowns and lower your monthly energy bills, we sat down with Marcus, one of our resident Master Appliance Technicians, to get his top professional refrigerator care tips.
Quick Answer: How to Keep a Refrigerator Running Efficiently
To maximize your refrigerator’s lifespan and efficiency, clean the condenser coils every 6 months, maintain a 1-inch clearance around the unit, change the water filter every 6 to 9 months, and avoid overloading the shelves. Keeping the temperature set between 37°F and 40°F ensures optimal food safety without overworking the compressor.

Why Refrigerator Maintenance Matters
The Importance of Proper Refrigeration Maintenance
Most homeowners view their refrigerator as a “set-it-and-forget-it” appliance. However, routine maintenance is the difference between a fridge that lasts 15 years and one that fails after just six.
According to Appliance EMT, proper refrigerator maintenance provides three massive benefits:
- Drastically Lowers Energy Bills: When a refrigerator is neglected, its mechanical parts have to work twice as hard to maintain freezing temperatures. This causes a stealthy spike in your monthly electricity costs.
- Prevents Food Spoilage: A poorly maintained fridge suffers from inconsistent airflow and temperature fluctuations. This creates “warm zones” where bacteria thrive, leading to premature milk spoilage and wasted groceries.
- Extends the Lifespan of the Compressor: The compressor is the “heart” of your refrigerator. Replacing one can cost almost as much as buying a brand-new appliance. Routine care keeps the compressor running cool and unstressed.
“Think of it like changing the oil in your car,” says Marcus. “A little bit of regular attention completely prevents the catastrophic mechanical breakdowns that leave you scrambling on a weekend.”
10 Master Technician Care Tips for Your Refrigerator
1. Clean the Condenser Coils on a Regular Basis
Your refrigerator relies on condenser coils to dissipate heat. Over time, these coils (typically located at the bottom or back of the unit) collect a thick layer of dust, pet hair, and cobwebs.
“When coils get dirty, they act like an insulating blanket,” Marcus explains. “The fridge can’t rid itself of heat properly, forcing the compressor to run hotter and longer. This drastically shortens the lifespan of your appliance and spikes your electric bill.”
The Fix: Pull off the base grille and use a coil brush or a vacuum hose attachment to clean them out every six months. If you have shedding pets, make it every three months.

2. Leave at Least 1 Inch of Space Between the Refrigerator and the Wall or Cabinet
Your refrigerator needs breathing room. Make sure it has at least 1 inch of space between the unit and the wall, cabinet, or surrounding enclosure.
That space helps heat escape and allows the refrigerator to operate more efficiently. If the refrigerator is pushed too tightly against the wall or built into a space without proper clearance, heat can become trapped around the appliance.
This forces the refrigerator to run longer and harder than necessary.
Marcus notes that poor clearance is often overlooked. “Homeowners focus on the inside of the refrigerator, but the outside matters too,” he says. “The unit needs space around it so it can release heat.”
The Fix: Always ensure your refrigerator is sitting level and has at least 1 inch of clearance space between the unit and the surrounding cabinets or walls. This small gap allows warm air to escape efficiently.
3. Make Sure the Refrigerator is Sitting Level
If your refrigerator is tilted forward or severely uneven, it causes more than just a crooked aesthetic. An unlevel fridge can prevent the doors from sealing completely under their own weight, letting cold air escape. It can also cause internal fluids to pool improperly, putting undue strain on the cooling system.
Appliance EMT technicians recommends checking that the refrigerator is stable and balanced. If it rocks when touched or the doors swing open or fail to close on their own, it may need adjustment.
The Fix: Place a carpenter’s level on top of the fridge. Adjust the leveling legs at the front base until the unit is perfectly balanced or has a very slight tilt backward to help the doors swing shut automatically.
4. Do Not Overload Your Refrigerator
It’s tempting to stock up to the brim during grocery runs, but packing your refrigerator too tightly is a recipe for premature wear and tear.
“Refrigerators cool by circulating chilled air,” says Marcus. “If there’s no room for the air to move, you’ll end up with warm pockets where food spoils quickly, and your compressor will work overtime trying to drop the temperature. In Addition, it can keep your refrigerator from closing properly leading to a loss in cold air.”
The Fix: Keep your fridge about ¾ full. This leaves enough thermal mass to maintain temperature when the door opens, but leaves plenty of room for proper air circulation.
5. Do Not Block the Air Vents
Inside your fridge and freezer, there are small vents that allow cold air to travel between compartments. Shoving a large box of pizza or a giant gallon of milk directly in front of these vents halts airflow entirely.
Blocked vents can cause several issues, including:
- Warm sections inside the refrigerator
- Frozen food in the fresh food section
- Longer run times
- Ice buildup
- Inconsistent freezer performance
Marcus recommends homeowners take a quick look inside the refrigerator after putting away groceries. “Make sure nothing is pushed directly against the vents,” he says. “That one habit can prevent a lot of cooling complaints.”
The Fix: Locate your unit’s internal vents and make a habit of keeping a 2-to-3-inch clear zone around them.
6. Change Your Water Filter Every 6 to 9 Months
If your refrigerator has a built-in water dispenser or ice maker, it relies on a water filter. Neglecting to change this filter can affect water taste, reduce water flow, and place unnecessary strain on the water system. It may also contribute to slow ice production or dispenser issues.
The Fix: Replace your water filter every 6 to 9 months. If you have a large family or exceptionally hard local water, aim closer to the 6-month mark. Regular replacement keeps your ice tasting fresh and prevents calcium buildup from clogging internal valves.
If your refrigerator has a filter indicator light, do not ignore it. If it does not have one, set a reminder on your phone or calendar.
Helpful rule: If your water tastes different, the dispenser flow is slower than usual, or the ice looks cloudy or tastes off, check the filter first.
PRO TIP FROM MARCUS:
“If your water dispenser suddenly starts trickling slowly, don’t assume the pump is broken. 9 times out of 10, a heavily clogged water filter is the culprit.”
7. Inspect and Clean the Door Gaskets
The rubber seals (gaskets) around your refrigerator doors are what keep the cold air in and the warm room air out. If they are dirty, sticky, or cracked, cold air constantly escapes.
The Fix: Wipe down the gaskets with warm, soapy water once a month to remove sticky residues that can tear the rubber.
The Dollar Bill Test: Close the refrigerator door on a dollar bill. If you can pull the dollar bill out easily without any resistance, your seal is weak and the gasket likely needs to be replaced.
8. Let Hot Leftovers Cool Down First
Placing a piping-hot pot of soup or a warm casserole directly into the fridge forces the appliance to fight an immediate thermal spike. The internal temperature of the fridge will rise, temporarily endangering nearby items like milk or eggs, and forcing the compressor into overdrive.
The Fix: Let your leftovers sit on the counter for 20 to 30 minutes to cool down to room temperature before sealing and refrigerating them.
9. Keep the Refrigerator at the Right Temperature
Temperature settings matter. If the refrigerator is too warm, food can spoil faster. If it is too cold, items may freeze and the unit may waste energy.
A good target range is:
- Refrigerator: Around 37°F
- Freezer: Around 0°F
Use an appliance thermometer if you are unsure whether your refrigerator is actually reaching the temperature shown on the control panel.
If your refrigerator cannot maintain safe temperatures, even after adjusting the settings, it may be time to schedule a professional inspection.
10. Keep Food Covered
Uncovered food releases moisture into the air inside your refrigerator. The appliance’s built-in dehumidifier and compressor then have to work twice as hard to remove that moisture from the environment.
The Fix: Always store leftovers, fruits, and vegetables in airtight containers or tightly wrapped bags. It keeps your food fresher and prevents your fridge from working extra shifts.
When to Call in the Professionals
While these maintenance tips will prevent a massive percentage of common refrigerator issues, major components like the compressor, evaporator fan, or control board require expert hands.

Frequently Asked Questions About Refrigerator Care
How long does a typical refrigerator last?
On average, a well-maintained refrigerator lasts between 10 to 15 years,” says Marcus. However, the actual refrigerator lifespan depends entirely on how well it’s cared for. Neglecting to clean the condenser coils or constantly overloading the shelves can cut that lifespan in half by wearing out the compressor prematurely.
Why is my refrigerator constantly running?
If your fridge rarely shuts off, it’s usually because it is struggling to maintain its cool temperature. The most common culprits are dirty condenser coils, blocked internal air vents, or a failing door gasket. If you’ve cleaned the coils and checked the seals and it still won’t stop running, it’s time to call a professional technician to check the thermostat or refrigerant levels.
Is it worth repairing an older refrigerator or should I replace it?
As a general rule of thumb used by Appliance EMT since 2005, if a repair costs less than 50% of the price of a brand-new refrigerator and your unit is under 10 years old, repairing it is almost always the more cost-effective choice. Modern, high-end fridges are complex machines, and a quick component replacement by a certified tech can easily add another 5 or 6 years to your appliance’s life.
Why is there water pooling at the bottom of my fridge or on the kitchen floor?
This is usually caused by a clogged defrost drain line. When the small drain hole inside your freezer gets blocked by food particles or ice chunks, the defrost water overflows and leaks down into the fresh food compartment or onto your kitchen floor.
