Refrig PTC Relay 2Pin

Description

Universal 2-Pin Refrigerator Compressor PTC Starter Relay ### Product Overview This 2-Pin PTC (Positive Temperature Coefficient) Starter Relay is a solid-state electronic component designed to initiate the start cycle of fractional horsepower refrigerator and freezer compressors. Unlike older mechanical coil relays, a PTC starter relies on a specialized ceramic resistor disc inside. When the refrigerator turns on, the disc allows a strong current to kickstart the compressor’s auxiliary start winding. Within seconds, the disc heats up, its resistance rises dramatically, and it safely shuts off the start winding—leaving the compressor running efficiently on its main winding. ### Key Features Solid-State Reliability: No moving internal parts or mechanical plungers to wear down or bind, providing silent and dependable switching. Standard 2-Pin Configuration: Features two male spade quick-connect terminals, allowing easy integration with running capacitors or direct line wiring. Universal Resistance Compatibility: Commonly available in standard resistances (such as 4.7Ω, 12Ω, 15Ω, or 22Ω) to match various compressor sizes. Compact Plug-On Design: Snaps directly onto the compressor’s lower run and start terminal pins, fitting securely under the plastic terminal housing. ### Product Compatibility & Sizing Specifications PTC relays are highly interchangeable universal parts. To guarantee a perfect fit, match the number of pins (2 Pins), the physical shape, and the resistance value (Ohms) printed on your old relay. Direct Replaces & Equivalent Configurations: QP2 Series: QP2-4.7, QP2-12, QP2-15, QP2-22 (2-pin versions) MZ92 / MZ93 Series: MZ92-15Ω, MZ92-22Ω, MZ93-12Ω ZHB Series: ZHB54-120P15, ZHB69-120P15, ZHB75-120P15, ZHB60-120P15 Compatible Appliance Types: Standard household single-door and double-door kitchen refrigerators. Compact mini-fridges, office bar coolers, and under-counter beverage centers. Chest freezers, upright deep freezers, and wine chillers. Portable car refrigerators and outdoor camping freezers. Common Compatible Appliance Brands: Because this part functions as a standardized replacement module, it is compatible across an array of major global compressor and appliance brands, including: Midea / Danby / Haier (Extremely common in mini-fridges and compact freezers) Whirlpool / Kenmore / Maytag / Frigidaire LG / Samsung / Panasonic Vissani / EdgeStar / Summit / Igloo / RCA ⚠️ Installation Note: If your refrigerator turns on, clicks every few minutes, but the compressor fails to run or get cold, the internal ceramic disc inside this relay has likely cracked or shattered. When replacing, ensure the terminal layout matches your original wiring. Always unplug the appliance from the wall before attempting the swap.
