So, No plumbing connection needed. It’s a closed-loop, passive system that relies on gravity and waste heat—a simple, elegant piece of engineering you probably never see working, until it breaks.
The journey begins with the fundamental physics of refrigeration. Your fridge cools its interior by running a refrigerant through evaporator coils. These coils get cold—typically between -10°C and -20°C (14°F to -4°F). A fan circulates warm, humid air from the fridge compartment over these coils. fridge drain hole where does the water go
Crucially, this pan sits directly above or adjacent to the and condenser coils , which get hot during operation (up to 60–90°C / 140–194°F). The heat radiates upward into the pan. So, No plumbing connection needed
To prevent ice from blocking airflow and ruining cooling efficiency, the fridge enters a (usually 1–4 times per day, lasting 15–30 minutes). A heating element under the evaporator coils warms up, melting the frost into liquid water. Your fridge cools its interior by running a
