It provides the initial current surge needed to start the compressor motor, then quickly reduces current once the motor is running. The built-in overload protector monitors motor current and shuts the compressor down if it draws too much, protecting the appliance from damage.\u003c\/p\u003e\n\u003ch4\u003eQ: How do I know which pin configuration (1\/2\/3\/4 pin) to choose?\u003c\/h4\u003e\n\u003cp\u003eA: Check your existing starter relay or your refrigerator's compressor terminal block. Count the number of connector pins on the original part and select the matching option (1-pin, 2-pin, 3-pin, or 4-pin). If unsure, consult your appliance's service manual or the compressor model number for guidance.\u003c\/p\u003e\n\u003ch4\u003eQ: Is this relay compatible with my refrigerator brand?\u003c\/h4\u003e\n\u003cp\u003eA: This is a universal PTC starter relay designed to be compatible with a wide variety of refrigerator and mini fridge brands. Please verify that the pin count, resistance (15 ohm or 22 ohm), and voltage (220V) match your appliance's specifications before purchasing.\u003c\/p\u003e\n\u003ch4\u003eQ: Is this starter relay easy to install without professional help?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! The relay simply clips onto the compressor's terminal pins — no soldering or special tools are required. Most DIY-savvy homeowners can complete the swap in just a few minutes. Always unplug the appliance before servicing any internal components.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
