To prevent future clogs, a common modification is utilized by technicians and homeowners alike: the "drain heat trap." This involves wrapping a piece of thick copper wire around the defrost heater element and extending the other end down into the drain hole. During the defrost cycle, heat is conducted directly down the wire into the drain hole, preventing water from refreezing inside the opening.
The modern refrigerator is a marvel of thermodynamic engineering, yet one of its most common failure points is also one of its smallest components: the defrost drain . When functioning correctly, this drain is invisible to the user. When clogged, it causes water pooling, ice buildup, and eventual compressor failure. This paper outlines the function, failure modes, and remediation of the refrigerator defrost drain. defrost drain fridge
