Product Configuration
The refrigerator defrost heater is a high-performance replacement part engineered for household and commercial fridges, freezers, and wine coolers, designed to melt frost and ice on evaporators, drain pipes, and condensed water pans.
The refrigerator defrost heater built with a premium Cr20Ni80 nickel-chromium heating core and 304 stainless steel tube-resistant housing, it delivers fast, uniform heating with thermal conversion efficiency ≥95%, effectively solving frost buildup, poor cooling, and water leakage caused by faulty defrost systems.
The refrigerator defrost heater universal fit for 95% of mainstream brands (Samsung/LG/Whirlpool/Frigidaire/Bosch/Haier), defrost heater tube is available in 110V/220V voltage and multiple power/size options. And this refrigerator defrost heater features IP65 waterproof, anti-condensation, and V-0 flame retardant design, with insulation resistance ≥100MΩ for safe use in low-temperature, high-humidity fridge interiors. Easy DIY installation with included mounting clips—no professional tools needed, restores your fridge’s optimal cooling performance in 10 minutes. CE/ROHS certified, service life ≥8000 working hours, equivalent to original factory parts.

Product Features
1. Refrigeration-Specific Design, Fast Defrost
The refrigerator defrost heater built-in Cr20Ni80 nickel-chromium alloy heating core, thermal conversion efficiency ≥95%, rapid heating to melt frost/ice in minutes, shortens defrost cycle and reduces fridge energy consumption.
2. Universal Fit for Most Brands
Defrost heater element standardized dimensions and wiring design, compatible with household top-freezer, bottom-freezer, side-by-side and French door fridges/freezers, fits major global brands (Samsung/LG/Whirlpool/Frigidaire/Bosch).
3. Corrosion & Low-Temp Resistant
Protective housing made of 304 stainless steel/heat-resistant plastic, anti-corrosion, anti-condensation, stable performance in fridge’s low-temp environment (-40℃ ~ 200℃), no cracking or aging.
4. Safe & Reliable, No Overheating Risk
Mild heating design (no hot spots), built-in thermal protection (optional), insulation resistance ≥100MΩ (DC500V), CE/ROHS certified, no electric leakage or component damage risk.
5. Easy DIY Installation
Compact size, comes with matching mounting clips/wires, direct replacement for original faulty heater, no soldering or professional repair needed—install in 10 mins with basic hand tools.
6. Multiple Sizes for All Defrost Zones
The refrigerator defrost heater available in tube/rod/tape types for evaporator, drain pipe and water pan defrost, multiple voltage (110V/220V) and power options to match different fridge models/sizes.
Product types
Our refrigerator defrost heaters are classified by installation position (the key to selection), with three mainstream types for different defrost zones of fridges/freezers—all with industrial-grade sealed structure for fridge’s high-humidity environment.
1. Evaporator Defrost Heater (Tube/Rod Type - Most Common)
Core Application: Main defrost for fridge/freezer evaporators (the core cooling part)
Structure: Cr20Ni80 heating core + 304 stainless steel tube + magnesium oxide insulation + waterproof sealed terminals
Key Feature: Rigid structure, the defrost heater is easy to mount on evaporator fins, uniform heating to melt frost on cooling coils
2. Drain Pipe Defrost Heater (Tape/Wire Type)
Core Application: Anti-freeze for fridge drain pipe/water pan, prevent ice blockage and water leakage
Structure: Ni-Cr heating wire + glass fiber/silicone insulation + self-adhesive backing
Key Feature: Flexible, the defrost heater element can be wrapped around drain pipes, small size, fits narrow fridge spaces
3. Mini Defrost Heater (Chip Type)
Core Application: Small fridges, bar fridges, wine coolers (compact evaporators)
Structure: Thin film heating core + heat-resistant ceramic base + insulated leads
Key Feature: Ultra-compact, low power, perfect for small refrigeration equipment with limited space
Product Application
1. cold storage cooling fan : tubular defrost heater used for unit cooler evaporator defrost, prevent frost accumulation affect refrigeration efficiency ;
2. cold chain equipment : U shape defrost heater Maintain the constant temperature environment of refrigerated truck and display cabinet to avoid frost resulting in temperature control failure ;
3. industrial refrigeration system : defrost tube heater is integrated in the bottom of the water pan or condenser to ensure the continuous operation of the equipment
