Coil Relay 1/4

Description

1/4 HP Refrigerator Compressor Coil Start Relay (Heavy Duty Mechanical Starter) ### Product Overview This Mechanical Coil Start Relay is an electromechanical starter designed specifically for mid-sized fractional horsepower refrigerator and freezer compressors rated at 1/4 HP (approximately 180W). Featuring an internal electromagnetic copper winding, it provides a high-torque mechanical snap-action kickstart whenever your refrigerator cycles on. When power hits the coil, it instantly pulls up an internal plunger to energize the compressor’s start winding. As the motor reaches its full running speed, the current drops, allowing gravity to cleanly drop the plunger and disconnect the start winding—preventing motor burnout and ensuring maximum operational efficiency. ### Key Features Electromechanical Dependability: Traditional mechanical current relay design offers a robust alternative to temperature-sensitive PTC solid-state stone relays, making it highly resilient against ambient kitchen heat and minor voltage fluctuations. Optimized Core Resistance: Precision-calibrated copper windings engineered to deliver the exact pull-in and drop-out current thresholds required for standard 1/4 HP refrigeration systems. Heavy-Duty Casing: Enclosed in a flame-retardant, high-insulation composite shell featuring heavy-gauge brass/copper terminal flags. Standard Push-On Terminal Setup: Designed for quick, slide-on mounting directly onto the compressor pins, pairing seamlessly with standard thermal overload protectors. ### Product Compatibility & Cross-Referencing To ensure this universal replacement part matches your appliance, verify that your old compressor is rated at 1/4 HP, operates on your regional household voltage (115V or 220V), and utilizes the same pin configuration. Direct Replaces & Equivalent Configurations: Appli Parts: APSR-141 Series (1/4 HP mechanical starter) Supco / Smart Electric: RO-41 / SE1/4R Series (Push-on style mechanical current relays) GE / Coldparts: KPM71 / 3ARR12 series current starters Universal Applications: Often acts as a direct replacement for legacy “hammer” or “bullet” style mechanical relays matching standard PW and EM series fractional compressor parameters. Compatible Appliance Types: Standard domestic kitchen refrigerators and large side-by-side family fridges. Mid-sized chest freezers and upright deep freezers. Commercial beverage display coolers and under-counter restaurant chillers. Heavy-duty water fountains and office water coolers. Common Compatible Compressor & Appliance Brands: Because it serves as a standardized functional replacement module, it fits a wide spectrum of compressor lines used by major appliance brands worldwide, including: Whirlpool / Kenmore / Maytag Frigidaire / Electrolux GE (General Electric) / Hotpoint Danby / Haier / Midea Embraco / Secop / Danfoss (Commonly found on standard 1/4 HP cooling units) ⚠️ Installation Note: Mechanical coil relays are gravity-dependent. They must be installed right-side up (usually indicated by an arrow or the word “TOP” marked on the housing) so the internal plunger can drop and disengage freely. Mounting the relay upside down will keep the start winding permanently energized, burning out your compressor. Always ensure the refrigerator is completely unplugged before replacing this part.
