1. Problem: it’s always working
An efficient refrigerator shouldn’t work all the time. Not only is a refrigerator noisy, it can take a big bite out of your wallet, too. Refrigerators are already one of the most energy consuming appliances. Allowing your refrigerator to run non-stop can drive your energy bill through the roof.
Cause 1: One of the most common causes of a refrigerator running too frequently (or worse, constantly) is the accumulation of debris and dust around the condenser coils. It is especially common if you live in a dusty environment or have multiple pets.
Solution: First, unplug the refrigerator from AC power. For most refrigerators, the condenser coils are located at the bottom and are generally accessible from the front or rear. (However, some newer models have internal coils.) To access the coils, find the grill and remove it by taking out the clips that hold it in place or by unscrewing it if it is bolted on. Use a vacuum cleaner to remove most of the build-up. If there is a lot of debris, use a brush or cloth to carefully remove the remaining debris. Replace grill and restore power to refrigerator.
Cause 2: Setting the refrigerator temperature too low will cause the refrigerator to work overtime and may even freeze and spoil some foods.
Correction: Usually you want to set your refrigerator between 37 and 40 degrees Fahrenheit (2.8 and 4.4 degrees Celsius). Put a thermometer in a glass of water, place the glass on the middle shelf of the refrigerator, and let it sit for at least 8 hours. Periodically adjust the temperature of your refrigerator to bring it slowly to the desired temperature. If this doesn’t fix the problem, see a professional as you may have a faulty part, such as a condenser, thermostat sensor, or fan motor.
2. Problem: water is dripping
Water collecting under the refrigerator is never a good sign, but it is also quite common and can usually be fixed relatively easily. Water loss is usually due to one of two problems.
Cause 1: A blocked defrost drain is one of the most common causes. This happens when food particles or other debris clog the drain hose, which can lead to ice formation and eventually a water leak from the freezer and refrigerator.
Solution: First, try flushing the drain from inside the freezer with warm water, using a turkey stick or small funnel. You can also try using a pipe cleaner or straightened coat rack to forcefully remove the socket. If this does not solve the problem, it may be necessary to manually remove debris clogging the check valve at the end of the drain hose.
Pull the refrigerator away from the wall and locate the defrost drain hose on the lower rear service panel. This hose should have a rubber check valve, which helps regulate humidity and is known to trap debris and clogs. Clean the valve with warm soapy water and reinstall the valve.
Cause 2: Every once in a while, a blocked or frozen water supply line causes water to settle under the refrigerator. It will also affect the ice production of the ice maker and slow or stop the flow of water from the dispenser.
Solution: First, unplug the refrigerator and locate the shutoff valve, usually under the sink, behind the refrigerator, or under the refrigerator in the basement. Make sure this valve is closed and look for leaks, kinks, or obstructions in the plastic supply line.
If there is a break or break in the line, replace the water supply line. Typically this line is a nylon tube with threaded compression fittings on both ends. You can find DIY waterline kits for sale at your local hardware store ($ 13). They are easy to connect, although you may need a key on hand. You shouldn’t over-tighten your accessories, so you won’t need as much force.
If the waterline is intact, but you see a translucent block, the culprit is ice. Just leave the refrigerator unplugged for about 2 hours to remove the socket. If the blockage is not clear, consult a professional before attempting to remove it. Once the line has thawed, plug the refrigerator back in and push it against the wall.
