The weather's hot, and the beverages stored in your fridge are lukewarm. You remember experiencing the same warm fridge issue last summer and wonder if you need to spring for a new major appliance.

Before spending the cash for a replacement, it's worth seeing if there's a simple explanation or if the problem is more serious and requires professional help.

What Would Cause a Refrigerator to Stop Getting Cold or Become Warm?

A fridge is an essential appliance that runs continuously. It's sensitive to issues affecting its efficiency, which may result in the fridge not getting cold enough. This issue isn't just an inconvenience; if food isn't kept cold enough, it can spoil. A warm fridge provides an ideal breeding ground for harmful microorganisms that may cause food poisoning.

Here are some common reasons your fridge may be too warm:

Wrong temperature setting. When the thermostat is set too high, your refrigerator won't get cold enough. If the fridge has a dial thermostat, it should be set just above the midpoint or slightly higher in summer. If it has an electronic display, it should be set at 40 degrees Fahrenheit or lower.
Opening the door too often. If your family opens the fridge door frequently, the interior may not have enough time to cool down properly. You might notice the fridge cools down overnight but feels too warm inside during the day.
Too much stored food. Cool air can't circulate properly in a packed fridge. Food at the back may get cold, but items stored on the door might feel warm.
Door doesn't seal. If the door isn't sealed, warm air can seep into the fridge. This can occur if stored items are keeping the door from closing properly or the door itself is misaligned.
Blocked vents. Some fridges have vents that supply cool air from the evaporator. If these are blocked by ice or stored food, the fridge may not cool sufficiently.
Faulty thermostat or control board. A technician may be able to replace a defective thermostat or control board.

What Temperature Should a Refrigerator Be Set at?

According to the Department of Energy, the optimum refrigerator temperature is 37 degrees Fahrenheit. The ideal temperature range inside a fridge is 35-38 degrees Fahrenheit, while freezers should be set at 0 degrees Fahrenheit or lower. The actual temperature inside a fridge varies. Typically, it's slightly warmer at the top and colder at the bottom, while door shelves are somewhat warmer.

Is My Food Safe If My Refrigerator Is Warm?

No, your food may not be safe if your fridge is warmer than 40 degrees Fahrenheit. Perishables such as milk, cheese, meat and cooked food can spoil quickly if the refrigerator isn't cold enough. Bacteria thrive at temperatures within the danger zone, between 40 and 140 degrees Fahrenheit.

Why Is My Freezer Cold But My Refrigerator Is Warm?

Although you might think the temperature in the fridge and freezer would be aligned, this isn't always the case. If your freezer is cold but the refrigerator is warm, you may be experiencing one of these issues:

Frozen evaporator coils. In frost-free fridges, the evaporator coils sit behind a removable cover and a fan transfers cool air to the fridge. In hot weather, or when the fridge is full, excessive ice can build up on the evaporator and block the flow of cool air.
Refrigerator temperature settings are too warm. If your appliance has separate thermostats for the freezer and fridge compartments, the fridge setting may be too high.
Dirty condenser coils. If the condenser coils located at the bottom or back of the appliance are dirty, they can't efficiently release heat captured inside the fridge and the interior won't be cold.
Refrigerant leak. With a refrigerant leak, you'll notice the fridge doesn't get cold but the freezer compartment does. As more refrigerant leaks out, the freezer will also start to warm up.
Faulty compressor. If the compressor is failing, your fridge won't get cold enough.

How to Fix a Refrigerator That Won't Get Cold Enough

If your refrigerator won't get cold, it's worth trying the following DIY fixes before calling for expert help. You can use a portable thermometer to check if the fix works.

Defrost the fridge. Be sure to allow enough time for any ice to melt. Don’t try to hurry the process by using any type of heat source, or you could damage the fridge lining.
Check the temperature settings. Make sure the temperature is set within the correct range. Try adjusting the thermostat knob to a colder setting to see if this fixes the problem.
Clean the condenser coils. Pull the refrigerator out and clean the condenser coils. When you push it back, make sure there's 1 inch of clearance between the fridge and wall to allow for proper airflow, and leave sufficient space on either side for ventilation.
Check for and replace damaged door seals. The seal should make contact along its entire length. If the seal is cracked, broken or not making contact, buy a new one for your make and model and replace it.
Avoid leaving the door open in hot weather. Warm air from the kitchen will quickly replace cold air in the fridge if you open the door repeatedly or leave it open longer than necessary.
Don't put hot food in the fridge. Allow hot food to stand on the counter for 20 to 30 minutes before stowing it in the fridge. When you place excessively hot food inside, the interior gets warmer and the compressor runs continually until it cools down.

If All Else Fails, Call a Refrigeration Technician

If the above DIY fixes don't work, it's time to call a refrigerator expert. A refrigeration technician can diagnose what's wrong and give you a quote for repairing the fridge. If the appliance is older or can't be repaired, you can make an informed decision about buying a replacement.
