Putting dry ice in a refrigerator can cause several potential issues and may lead to the refrigerator not working correctly. Here are some possible ways dry ice could have affected the refrigerator:
Temperature Extremes: Dry ice is extremely cold, with temperatures around -109.3°F (-78.5°C). Placing dry ice directly inside the refrigerator can cause a sudden drop in temperature, which might damage the refrigerator's internal components, including the thermostat, compressor, and other sensitive parts.
Thermal Shock: Introducing such a cold substance into a closed, confined space like a refrigerator can cause thermal shock. This sudden change in temperature could lead to the cracking of components or damage to the refrigerator's insulation.
Condensation and Ice Formation: Dry ice undergoes sublimation, where it changes from a solid to a gas without becoming a liquid. As it sublimates, it releases carbon dioxide gas, which can increase the humidity inside the refrigerator. This added humidity might lead to condensation forming on electrical connections, controls, and circuit boards. Over time, this moisture can cause short circuits and damage electrical components.
Blocked Air Vents: Placing dry ice improperly or without proper ventilation might block air vents and inhibit proper airflow inside the refrigerator. This can disrupt the cooling process and cause uneven temperature distribution, leading to potential malfunctions.
Safety Features: Many modern refrigerators have safety features that prevent excessive cold temperatures. Introducing extremely low temperatures with dry ice might trigger these safety features, causing the refrigerator to shut down to protect itself from potential damage.
If your son-in-law put dry ice in the refrigerator and now it's not working, it's essential to take the following steps:
Unplug the refrigerator: First, unplug the refrigerator from the power source to prevent any further damage or potential hazards.
Let it return to room temperature: Allow the refrigerator to return to room temperature naturally. Avoid trying to force thaw it or using external heat sources.
Check for visible damage: Inspect the refrigerator for any visible damage, such as cracks, leaks, or signs of condensation on electrical components.
Contact a professional repair service: To assess the extent of the damage and ensure safe repairs, it's best to contact a professional appliance repair service. They can diagnose the issue, repair any damage, and restore the refrigerator to working condition.
Placing dry ice directly inside a refrigerator is not recommended, as it can have severe consequences for the appliance. Always use dry ice with caution and follow safety guidelines to avoid damaging your refrigerator or any other appliances.
