Yes, it is normal for a completed refrigerator to drop water after being turned off, especially if the refrigerator has an automatic defrost feature. Here's why:
Automatic Defrost: Many modern refrigerators come with an automatic defrost system that prevents frost and ice buildup on the evaporator coils. During normal operation, the refrigerator collects moisture from the air inside, which condenses on the cold evaporator coils. The automatic defrost system periodically activates a heating element to melt this frost, turning it into water.
Evaporator Pan: The water resulting from the automatic defrost process drips down from the evaporator coils and is collected in a shallow pan or tray located at the bottom of the refrigerator or in the rear. This pan is often referred to as the "evaporator pan" or "drip pan."
Evaporation: The water collected in the evaporator pan is left to evaporate naturally due to the warmth generated by the compressor and condenser coils. However, when you turn off the refrigerator, the compressor and condenser coils stop producing heat, and the water in the evaporator pan may not evaporate as quickly.
Water Release: As a result, you might notice some water dripping or pooling near the bottom of the refrigerator or on the floor shortly after turning off the refrigerator. This is the remaining water from the automatic defrost process, which did not have a chance to evaporate completely.
To address this issue, you can use a towel or sponge to absorb the excess water in the drip pan. Additionally, make sure to clean the drip pan regularly to prevent any unpleasant odors or the growth of mold or mildew.
If you notice a large amount of water pooling or leaking continuously after the refrigerator has been turned off, it may indicate a problem with the defrost system, such as a clogged drain line or a malfunctioning defrost timer. In such cases, it's best to have the refrigerator inspected and repaired by a qualified appliance technician.
