Fridge Whirlpool Bimetal

Description

Whirlpool-Style Cylindrical Refrigerator Defrost Thermostat (2-Wire Clip-On)Product DescriptionKeep your frost-free refrigerator running at peak performance with this high-quality 2-wire defrost thermostat bimetal. Featuring a distinct round, barrel-style design, this thermal switch clips directly onto the evaporator coil tube inside your freezer compartment. Its primary function is to monitor coil temperatures and regulate the automatic defrost cycle, preventing ice from suffocating the cooling system.When the freezer coils drop to a freezing threshold during operation, the internal bimetal disc snaps shut to complete the electrical circuit to the defrost heater. Once the heater successfully melts the frost and the temperature climbs past the cutout limit (typically 50°F / 10°C), the thermostat instantly breaks the circuit. This precise operation keeps your fresh food perfectly chilled while ensuring the heater doesn’t run long enough to damage internal plastic walls.Key FeaturesHeavy-Duty Tube Clip: Equipped with a built-in metal spring clip designed to snap tightly onto standard $frac{3}{8}text{-inch}$ or $frac{1}{2}text{-inch}$ evaporator lines for maximum temperature accuracy.Hermetically Sealed Barrel: The cylindrical switch body is tightly insulated in a protective rubberized cap to seal out moisture, condensation, and ice buildup.Standard 2-Wire Harness: Comes pre-wired with two flexible leads (typically Pink/Blue or Black/Blue) terminated with a specialized inline connector plug for a tool-free connection.Compatible Mechanisms & Appliance BrandsThis circular 2-wire component is an iconic design utilized across millions of mechanical and early electronic refrigerator defrost systems. It is directly compatible with the following mechanisms and brands:Whirlpool: A direct fit for standard top-freezer and side-by-side configurations. It replaces widely used factory part numbers such as WPW10225581, W10225581, 2321799, and 4387503.Kenmore / Sears: Works seamlessly with Kenmore models built on the Whirlpool chassis (model prefixes like 106.xxxx or 596.xxxx).Maytag & Amana: Universally compatible with older and modern double-door platforms utilizing the single-barrel clip thermostat near the top hook of the evaporator coils.KitchenAid & JennAir: Fits built-in or freestanding premium models that route their automated defrost cycles through a traditional 2-wire thermal limit line.🛠️ Installation Tip: When installing, ensure the metal face of the circular thermostat is pressed flat and firm against the bare copper or aluminum evaporator tube. Use the attached metal clip to lock it securely in place—loose contact can cause the sensor to misread temperatures, leading to incomplete defrosting cycles.
