Why is My Refrigerator Not Cooling

If your refrigerator is not cooling, you may think it is broken. However, many things can cause this problem. Here are some things to check before calling an appliance repair specialist:

Check the circuit breaker.

To troubleshoot your refrigerator, start by checking the circuit breaker. If the circuit breaker is tripped, you must reset it before the refrigerator can continue operating.

If the circuit breaker has not been tripped and there are no other problems with your appliance, move on to check the compressor.

If you notice that your compressor is hot—a sign that it’s working too hard or has broken down—you should contact an appliance repair specialist immediately to get a replacement part sent out as soon as possible.

However, if this isn't an option for you because of time constraints or financial reasons, then we recommend taking another look at all wiring connections within your fridge until everything makes sense again;

-this may mean replacing some components with new ones or simply cleaning them off thoroughly enough, so they usually function again once moved back into place correctly without any obstructions blocking their path into functioning order again without fail, so make sure nothing goes wrong later down the line when trying to use them regularly instead

Check the compressor.

If your refrigerator isn't cooling, the first thing you'll want to do is make sure that your compressor is running.

-This is pretty easy: just look at it. If you see it spinning and making noise (it will probably be loud), that's good news.

If your fridge isn't cooling after checking the compressor, there are a few more steps to take.

The first step is to check the power supply. If there's no power coming into your home or apartment building, there won't be any way for your refrigerator's compressor or other features (like ice cube makers) to function correctly.

If you've confirmed that you have power going into either an outlet near where your fridge lives or directly into its box (sometimes this will look like an extension cord), then check out our next section where we talk about how condenser coils work and what happens when they fail as well as some things we can do if they fail anyway so keep reading below.

Check to wire.

Check for loose or broken wires if the fridge is still not cooling. If you find any, tighten them and see if that fixes the problem.

Leaning against your refrigerator can cause overheating of wires and break them over time, so make sure it's not touching anything when running.

Check the thermostat.

The first thing you should do if your refrigerator is not cooling correctly is check the thermostat.

Your refrigerator should have a thermostat that controls how cold your refrigerator or freezer compartment gets, and this can be adjusted using a dial or digital screen.

Have you checked to see that the thermostat isn’t set too low? If the temperature range on your refrigerator is set between 5°F (-15°C) and 41°F (5°C), then it may simply be too cold for food storage—and that can cause problems with how well items in your fridge stay fresh.

If this is the case, you might want to consider adjusting the temperature by 1 or 2 degrees.

It can be frustrating if you have a refrigerator that is not cooling. However, repairing the problem is not difficult if you follow the steps below:

Then remove any food inside your refrigerator and freezer before beginning service work on it.

You may also want to use an eraser brush at first because some frost buildup may make removing dirt more difficult than usual due to its stickiness property.

Also, disconnect any electrical connections leading into both compartments, including lights, if applicable; these may include light fixtures above shelves where light bulbs were installed previously, which could cause unwanted sparks while working with other tools like screwdrivers.

During maintenance procedures like cleaning out coils beneath refrigerators/freezers/refrigerators.

Where wires enter through openings near bottom corners, do take care when touching anything metallic while working on appliances.

Some metals get very hot quickly during operation periods, mainly when used heavily over long periods, without giving them time to rest between uses.

A few simple checks can resolve most refrigerator cooling problems.

If your refrigerator appears to be cooling correctly, but it's not keeping food cold, there are a few things you can check.

Check the thermostat: The thermostat is a simple device that turns the compressor on and off based on temperature changes inside the refrigerator.

If your refrigerator isn't cooling properly, check if this equipment is functioning correctly.

You can do this by placing a meat thermometer at various locations in your fridge —if all areas read below 35 degrees Fahrenheit, your thermostat may malfunction or break and need replacing (or could simply be set too high).

Check if there are loose wires: If you're confident that everything else seems okay with your fridge, but it still doesn't cool appropriately in some regions of the appliance (i.e., lower shelves), then make sure any wires or connections aren't loose before assuming anything else is wrong with your device.

Loose wiring can cause problems like heat generation within an electrical system; this creates additional work for components like compressors which don't have enough power to function at total capacity after suffering from increased heat over time due to faulty wiring."


If your refrigerator is not cooling, there are a few simple things to check. The most common cause of this problem is a faulty thermostat or compressor.

If you have an older-style refrigerator without an automatic defrost unit, you will need to defrost it manually (following the instructions in the user manual).

A qualified appliance technician should repair your refrigerator if none of these fixes work.
