Refrigerator Freezer Overload Relay Kit ZOU for Whirlpool Maytag GE

Description

Product Overview

The ZOU Refrigerator/Freezer Overload Relay Kit is engineered to provide a reliable, high‑performance solution for a wide range of residential refrigeration units. Constructed from a durable, heat‑resistant polymer housing and copper‑clad contacts, the kit delivers consistent electrical continuity while protecting the compressor from overload conditions. Each kit includes a four‑prong relay rated up to 4.7 ohms and an overload device capable of handling up to 1/4 horsepower, making it suitable for both standard and higher‑demand freezer applications. The kit conforms to the original equipment part numbers 4387913, 7020935, 4387766, 4387836, 4387836, 4241370, ensuring a perfect fit without the need for modifications. Package dimensions measure 2.09 × 2.05 × 1.26 inches and weigh only 1.13 ounces, allowing for easy storage and handling. Designed for compatibility with Whirlpool, Maytag, Frigidaire, GE, KitchenAid, LG, and Magic Chef models, this relay kit addresses a common failure point that can lead to compressor burnout, excessive energy consumption, and costly repairs.

Technical specifications include a rated voltage of 120 V AC, a current rating of 15 A, and a temperature operating range of –40 °C to +85 °C. The overload component features a fast‑acting thermal element that trips within seconds of an overcurrent event, providing an additional layer of protection beyond the mechanical relay. The relay’s four prongs are clearly labeled for straightforward wiring: prong 1 and prong 3 connect to the capacitor (if present), prong 2 receives the neutral line, and the hot wire attaches to the overload device. This logical layout simplifies installation for both professional technicians and DIY enthusiasts, reducing downtime and ensuring the refrigerator or freezer returns to optimal operation quickly.

Usage

This overload relay kit is intended for use in household refrigerators and freezers that experience intermittent cooling, compressor cycling, or audible clicking noises indicative of relay failure. It is especially valuable for homeowners who notice a rise in energy bills or for service technicians seeking a dependable replacement part that meets OEM standards. The kit can be installed in a variety of settings, including single‑family homes, multi‑unit apartment buildings, and small commercial kitchens where reliable refrigeration is essential. Because the kit is designed to handle a 1/4 hp load, it is suitable for both standard‑capacity units and larger, high‑efficiency models that demand more robust protection.

Installation requires basic electrical knowledge and standard hand tools. The process typically involves disconnecting power, removing the existing relay assembly, and mounting the new kit in the same location. Wiring follows a clear sequence: connect the hot line to the overload terminal, attach the neutral to prong 2, and, if a start capacitor is present, link it to prongs 1 and 3. Once secured, the unit is tested for proper operation before the appliance is returned to service. The compact size of the kit means it can be installed in confined spaces without the need for additional brackets or modifications, making it an ideal solution for retrofits and original equipment installations alike.

FAQ

What appliances are compatible with this overload relay kit?

The kit is designed for refrigerators and freezers from Whirlpool, Maytag, Frigidaire, GE, KitchenAid, LG, and Magic Chef that use the part numbers 4387913, 7020935, 4387766, 4387836, or 4241370.

Do I need any special tools to install the kit?

No special tools are required. A standard screwdriver set, wire strippers, and a multimeter for verification are sufficient for a safe and effective installation.

Can this kit be used in commercial refrigeration units?

While the kit is optimized for residential units rated up to 1/4 hp, it can be used in light‑duty commercial freezers that match the same electrical specifications. For larger commercial systems, a higher‑capacity overload relay is recommended.

How does the overload protection work?

The overload component contains a thermal element that reacts quickly to excess current. When an overcurrent condition occurs, the element trips, interrupting power to the compressor and preventing damage.

What is the warranty coverage for this product?

ZOU provides a one‑year limited warranty covering any manufacturing defects. The warranty does not cover damage caused by improper installation or external factors such as power surges.
