Ref 4TM Overload 1/6HP

Description

4TM Refrigerator Compressor Thermal Overload Protector (1/6 HP) ### Product Overview The 4TM Thermal Overload Protector (1/6 HP) is an essential electromechanical safety device engineered to protect standard residential mini-fridges, freezers, and water dispensers from compressor burnout. Packed inside a compact “butterfly” style housing, it utilizes a precision bimetallic snap-action disc coupled with an internal series heater. If your compressor struggles to start due to a faulty relay, encounters a voltage drop, or draws dangerously high current under heavy workloads, the bimetal disc triggers instantly to cut the electrical connection. Once the compressor shell drops back down to a safe, stable temperature, the switch automatically resets to restore normal cooling. ### Key Features Engineered for 1/6 HP Systems: Perfectly calibrated to match the thermal and electrical performance curves of standard 1/6 HP (~125W) refrigeration compressors. Dual Thermal-Current Sensing: Acts as a comprehensive safeguard by monitoring both the external operating temperature of the compressor shell and the current traveling through the motor windings. Direct Plug-On Assembly: Standard low-profile design slides directly onto the compressor’s common terminal pin, fitting securely beneath the protective terminal cover. Flame-Retardant Casing: Constructed with high-insulation materials and high-conductivity terminal tabs to reliably endure countless thermal cycling events. ### Product Compatibility & Sizing Specifications Because 4TM protectors are highly standardized replacement components, compatibility is determined by matching the horsepower rating (1/6 HP), operating voltage (typically 110V/120V or 220V/240V), and terminal layout. Direct Replaces & Equivalent Configurations: Sensata / Texas Instruments Klixon: Original 4TM Series (matches standard 1/6 HP codes such as 4TM265RFBYY, 4TM158NFBYY, or similar depending on regional voltage). Universal Replacements: Directly replaces any generic round, square, or flat overload protector rated specifically for 1/6 HP or ~125 Watts. Common Pairings: Typically paired with a 1-pin, 2-pin, or 4-pin PTC solid-state starter relay, or a 1/6 HP mechanical coil relay. Compatible Appliance Types: Standard household kitchen refrigerators and mid-sized compact mini-fridges. Domestic chest freezers and small upright deep freezers. Office water coolers, water dispensers, and countertop ice makers. Under-counter beverage centers and commercial display coolers using fractional compressors. Common Compatible Compressor & Appliance Brands: This universal protector directly fits micro-to-mid capacity compressors utilized by major appliance manufacturers globally, including: Embraco / Secop / Danfoss (Very common on standard EM, NE, and TLS series 1/6 HP compressors) Whirlpool / Kenmore / Maytag Frigidaire / Electrolux / GE (General Electric) Danby / Haier / Midea / Galanz / Panasonic ⚠️ Installation Note: Ensure the overload protector is pushed entirely and firmly onto the compressor pin. A loose connection will create localized electrical resistance, causing the protector to get artificially hot and trip continuously even if the compressor itself is perfectly healthy. Always ensure your refrigerator is completely unplugged before beginning the replacement.
