URCO410RC - Universal Supco Refrigerator 4 'N 1 Hard Start, Relay, Overload & Start/Run Capacitor Combo

URCO410RC – Universal Supco Refrigerator 4 ‘N 1 Hard Start Relay, Overload & Start/Run Capacitor Combo

The URCO410RC is a high-quality universal refrigerator compressor start kit designed by SUPCO for refrigerator compressor repair and performance restoration. This 4-in-1 hard start kit combines a relay, overload protector, start capacitor, and run capacitor into one complete replacement assembly for compatible refrigeration systems operating at 110–125 VAC and rated for 1/4 HP to 1/3 HP compressors.

Designed for domestic refrigerators and light commercial refrigeration systems, the URCO410RC is commonly used to restore compressor startup performance when original start components have failed or weakened. If your refrigerator compressor clicks repeatedly, struggles to start, overheats, or fails to cool properly due to relay or capacitor failure, replacing the start system with the URCO410RC often restores reliable operation.

Available from Appliance Kingdom with fast Canada-wide shipping for homeowners, landlords, and professional appliance repair technicians.

What Does the URCO410RC Do?

The URCO410RC is a universal compressor hard-start assembly that replaces four critical compressor starting components:

• Start relay

• Overload protector

• Start capacitor

• Run capacitor

It delivers the extra starting torque needed for hard-starting compressors while protecting against overload conditions and supporting smoother compressor operation.

SUPCO designed this unit for refrigeration systems that do not already have a separate run capacitor, making it an ideal all-in-one repair solution for many refrigerator compressor applications. It also helps older compressors start more efficiently and reduces low-voltage startup problems.

Correct electrical specifications are critical for compressor longevity. Installing the wrong relay or capacitor can damage compressor windings or cause repeated startup failure.

Common Symptoms Indicating Replacement

A failing compressor start system often causes noticeable refrigerator cooling problems, including:

• Refrigerator not cooling properly

• Compressor clicking repeatedly without starting

• Compressor hums but does not run

• Refrigerator starts intermittently

• Warm refrigerator compartment

• Compressor overheating

• Frequent overload shutdown

• Compressor starts only after multiple attempts

Replacing the URCO410RC can often restore startup performance when these symptoms are caused by failed start components rather than compressor mechanical failure.

Compatibility Guidance

The URCO410RC is designed for:

• Refrigerators using 110–125 VAC compressors

• Compressor sizes rated 1/4 HP to 1/3 HP

• Systems without an existing external run capacitor

• RSIR, CSIR, PSC, and CSR compressor applications within supported specifications

Before ordering:

• Verify compressor horsepower rating

• Confirm system voltage

• Confirm your compressor start configuration

• Verify wiring compatibility

Because incorrect installation can damage compressors, professional compatibility verification is strongly recommended.

Appliance Kingdom can help confirm fitment before purchase.

Key Features & Benefits

• High-quality universal SUPCO replacement design

• Combines relay, overload, start capacitor, and run capacitor

• Supports difficult compressor startups

• Helps prevent low-voltage starting failures

• Helps compressors run cooler and more efficiently

• Push-on mounting clip for simplified installation

• Designed for modern high-efficiency refrigeration compressors

Installation Overview

Installation difficulty: Moderate to Advanced

Installation requires:

• Accessing compressor electrical terminals

• Correct wire identification

• Matching compressor start/common/run terminals

• Verifying voltage and HP rating

• Safe handling of capacitor-based components

Because this is a live electrical refrigeration component, professional installation is strongly recommended unless the installer has refrigeration electrical repair experience.

Improper wiring can permanently damage the compressor.
