BigHead SH502 Refrigerator Drain Heater Wire Kit — 32-inch, 7-16-inch Tip, 120V 15W + Accessories

Efficient defrosting with the BigHead SH502 Kit

Keep your refrigerator operating at peak efficiency with the BigHead SH502 Refrigerator Drain Heater Wire Kit. This is not just a replacement part; it is a carefully designed DIY solution that addresses common frost and drainage challenges with real world practicality. The 32-inch heater wire with a 7-16 inch tip is engineered to integrate with the defrost system in many Samsung and Supco models, helping sustain consistent temperatures and smooth automatic defrost cycles.

Think of your fridge as a busy climate control hub. When the evaporator coil or upper fan experiences freezing, water can back up and ice can form along the drain path. The SH502 kit targets these trouble spots, working to minimize ice blockages and keep the drain clear. The result can be less manual intervention and steadier defrost cycles, which supports steady cooling performance and can contribute to extending the fridge's usable life over time.

What you get in the all-in-one package

The SH502 kit is designed to cut trips to the hardware store. It comes with a ready-to-install heater wire plus practical accessories that fit most small to mid-size fridge setups. Each item is selected to support quick, safe DIY setup.

• 1 SH502 Refrigerator Drain Heater Wire (32-inch long, 7-16 inch tip)
• 20 zip ties for secure heater positioning
• 1 heat resistant insulating tape for electrical safety
• 10 wire connectors to simplify wiring

Key specifications and safety notes

Designed to align with common defrost system requirements, the heater offers clear specs: 120V, 15W, and a 32-inch overall length with an 18-inch lead wires. The unit is water resistant in the drain area but not waterproof, and it should not be cut, spliced, or extended in the field. This ensures a straightforward, compliant upgrade that fits many standard fridges.

• 7-16 inch heater tip diameter for tight, efficient integration
• 18-inch lead wires for flexible routing
• Safety-first design to avoid improper modifications
• Water resistant protection against occasional moisture, with no submersion

Durable, long lasting build and versatile use

Crafted from high quality silicone cores and a robust outer braid, the SH502 is built to withstand temperature swings inside a busy kitchen appliance. The construction resists cracking and fraying, performing reliably across seasons. While designed for refrigerators, the heater wire also serves spot heating needs in drain pans, troughs, and related cooling equipment, expanding its value for multiple home or small commercial setups.

Easy installation and cost-conscious replacement

The installation process is designed for DIY enthusiasts: unplug the fridge, mount the heater, and connect the wires using the included components. This kit can act as a direct replacement for the original SH502, offering a budget-friendly option to service calls without sacrificing safety or performance.
