Is 45 degrees a safe temperature for a refrigerator? Keeping your refrigerator at 45°F may not keep your food fresh. According to the USDA, bacteria grows most rapidly in temperatures ranging from 40°F to 140°F, and fresh foods can spoil if they're exposed to temperatures above 40°F for more than two hours.
To ensure that your refrigerator is doing its job, it's important to keep its temperature at 40 °F or below; the freezer should be at 0 °F.
The USDA says refrigeration temperature should be 40°F (4.4°C) or below. If food is in there at a higher temperature (such as the 43-45°F the question mentions), for longer than 2 hours, and they're saying the food isn't safe.
There are several causes for a refrigerator that doesn't cool, including dirty condenser coils, poor ventilation, improper installation, faulty or dirty gasket seals, unorganized food storage, appliance location and malfunctioning internal parts.
In general, perishable foods like milk should not sit out of the refrigerator or cooler for longer than two hours. Cut that time down to an hour in the summer if the temperature reaches 90 degrees F.
One degree can affect milk quality. Temperature control is important in avoiding heat shock. Shelf life decreases as storage temperature increases. Store all dairy products in a properly refrigerated zone at 33°F to 38°F.
Maintaining the Safety of Milk: Refrigeration is the single most important factor in maintaining the safety of milk. By law, Grade A milk must be maintained at a temperature of 45 °F or below. Bacteria in milk will grow minimally below 45 °F.
Discard any refrigerated perishable food (such as meat, poultry, fish, milk, eggs or leftovers) that has been at refrigerator temperatures above 40°F for four hours or more.
While the optimal temperature for cheese is between 35 and 45 degrees Fahrenheit, Cabot cheeses are hardy enough to withstand a short time period without refrigeration.
Everything in your fridge typically chills at or just below 40 degrees Fahrenheit (4 degrees Celsius). Temperatures that climb above that level enter what's ominously referred to as the “Danger Zone.” Bacteria can grow quickly on perishable food kept at warmer temperatures.
Refrigerators should be set to maintain a temperature of 40 °F (4.4 °C) or below.
The Department of Agriculture states bacteria multiply quickly in the "Danger Zone," which is temperatures beginning at 40°F (4.5°C). It's best to set your temperature gauge a few degrees below that. Most experts recommend that the ideal temperature setting for a refrigerator is between 35-38°F (1.6-3.3°C).
For example, 45F (7C) air feels cold, but 45F (7C) water feels like it's burning your skin. Water has much greater density than air, it immediately destroys most of the insulation provided by your clothing, and it also conducts heat away from your body much faster than air.
Use straps to secure the refrigerator tightly to the hand truck, then tip the hand truck back to no more than a 45-degree angle. Be sure to enlist help when moving around corners, through doorways, and up or down stairs.
If the refrigerator temperature doesn't budge, try cleaning around the appliance's compressor and any coils to remove dust and dirt, which prevent efficient cooling, Chai says. Check your owner's manual for the coil location and vacuum them with a soft-bristle brush.
Reset your refrigerator
Follow the instructions below depending on your model and what you would like to reset: Reset your refrigerator: First, unplug it (or turn off the power at the circuit breaker), and then wait about five minutes for the electrical charge to clear out of it. Then, power it back on again.
A hum or a slight buzz is typical, but if your refrigerator starts making strange or loud noises, the compressor might be struggling. Professional Repair Required: Compressors have numerous components, and diagnosing the source of the noise can be complicated.

How long can you leave milk out of the fridge? The Food and Drug Association's (FDA) general rule for most perishable foods is: Don't leave them out of the fridge for more than two hours—even less if the room temperature where you are is hot.
Ideal Temperature Range for Beverages
White wines: 45°F to 50°F (7.2°C to 10°C) Red wines: 50°F to 65°F (10°C to 18.3°C) Beers: 45°F to 55°F (7.2°C to 12.8°C)
You can leave milk out of the fridge at room temperature for up to two hours, according to the USDA. “Leaving milk out too long can potentially lead to foodborne illness,” Amidor explains. “Pathogenic microorganisms like to grow in temperatures between 40 to 140 degrees.
Eggs and most pasteurized dairy products are actually okay up to 45 degrees F. It's not the ideal temperature for maximum shelf life, but it's considered safe. Many "mayonnaise-based condiments" as you described them are acidified to inhibit pathogen growth.
