ICG1 - Universal Supco Refrigerator Start Relay

ICG1 – Universal SUPCO Refrigerator Start Relay

The ICG1 is a Universal SUPCO® refrigerator start relay, designed for dependable compressor starting performance in residential and light commercial refrigeration systems. It is commonly used in refrigerators and freezers that require a reliable replacement for failing OEM start relays or mechanical relay systems.

Available through Appliance Kingdom (Canada-wide shipping), the ICG1 is a trusted OEM-equivalent refrigeration control component used by technicians to restore compressor startup reliability and cooling performance.

Function & Importance of the ICG1 Start Relay

The start relay is a critical electrical component in a refrigerator system. The ICG1 Universal Supco Refrigerator Start Relay is responsible for:

• Initiating compressor startup by supplying the initial electrical boost

• Safely disconnecting the start circuit once the compressor is running

• Supporting stable operation in 115V refrigeration systems

• Working with compressors in the 1/12 HP to 1/2 HP range

Without a functioning relay, the compressor may fail to start, struggle to run, or shut down repeatedly due to overload protection.

Using a high-quality universal relay like the ICG1 ensures proper electrical timing and reduces stress on the compressor motor—helping extend overall refrigerator lifespan.

Common Symptoms of a Failing Start Relay

A faulty or weakened refrigerator start relay often causes:

• Refrigerator not cooling properly

• Compressor clicking but not starting

• Intermittent startup or repeated cycling

• Loud humming followed by shutdown

• Overload protector tripping frequently

• Warm fridge or freezer despite power being on

In many cases, replacing the start relay restores normal compressor operation and cooling performance—provided the compressor itself is still healthy.

Compatibility Guidance

The ICG1 is a universal refrigerator start relay designed for:

• 115V refrigeration systems

• Compressors rated 1/12 HP to 1/2 HP

• Many residential refrigerator and freezer applications

Always verify your appliance model number and compressor specifications before ordering. Matching voltage and horsepower range is essential for safe operation and proper compressor performance.

Installation Overview

Installation of the ICG1 start relay is generally considered a moderate-level repair:

• Disconnect refrigerator power before service

• Remove existing start relay from compressor terminals

• Snap on the ICG1 relay using the bracket system

• Reconnect terminals securely according to wiring layout

• Restore power and test compressor startup

Professional installation is recommended if the compressor system is unfamiliar or if multiple startup components (relay, overload, capacitor) are being diagnosed together.
