RO41 - Universal Supco Refrigerator Relay & Overload

RO41 – Universal Supco Refrigerator Relay & Overload (Genuine Replacement Compressor Start Protection)

The RO41 is a universal OEM-grade compressor start relay and overload combination designed for refrigerator and light commercial refrigeration systems. This Genuine Supco component is widely used to replace failing or burned-out OEM start relays and overload protectors in compressors ranging from 1/4 HP to 1/3 HP (115V systems).

Available from Appliance Kingdom (Canada) with fast nationwide shipping, the RO41 is a trusted repair solution for restoring refrigerator cooling performance when the compressor is not starting properly or keeps tripping protection.

Function & Importance of the RO41 Relay & Overload

The RO41 plays a critical dual role inside a refrigerator compressor system:

1. Start Relay Function

• Helps the compressor motor start by briefly energizing the start winding

• Disconnects automatically once the compressor reaches running speed

2. Overload Protection Function

• Protects the compressor from overheating or locked rotor conditions

• Cuts power when electrical load exceeds safe operating limits

• Prevents permanent compressor damage

This combination ensures safe startup and operation of the refrigerator compressor. Without a properly functioning relay/overload, the compressor may fail to start or may overheat and shut down repeatedly.

Why OEM-Quality Matters

Using a properly rated universal relay like the RO41 is important because:

• Incorrect relay sizing can prevent compressor startup

• Poor-quality relays may overheat or fail prematurely

• Overload protection ensures compressor safety under stress

• Proper amperage rating (up to ~6.8A) is critical for reliability

A genuine Supco unit ensures stable performance and protects expensive compressor components from damage.

Common Symptoms of a Faulty Relay & Overload

If the relay/overload is failing, your refrigerator may show:

• Compressor clicks but does not start

• Refrigerator not cooling or cooling intermittently

• Repeated clicking or buzzing near compressor

• Compressor starts briefly then shuts off

• Burning smell near compressor area

• Overload trips repeatedly due to overheating

In many cases, replacing the RO41 restores normal compressor startup and cooling performance.

Compatibility Guidance

The RO41 is designed for:

• Refrigerators (domestic)

• Light commercial refrigeration units

• Compressors rated 1/4 HP to 1/3 HP, 115V

Always verify:

• Compressor horsepower rating

• Voltage (typically 115V in residential fridges)

• Terminal style compatibility (push-on/pin type)

If unsure, confirm your compressor label before ordering.
