If your refrigerator compressor clicks repeatedly, struggles to start, overheats, or fails to run while interior lights remain operational, replacing a failed relay and overload assembly with the URO81 often restores reliable compressor startup and cooling performance.

What Does the URO81 Relay & Overload Do?

The URO81 is a combined compressor start relay and overload protector that controls the refrigerator compressor’s startup cycle and safeguards the compressor motor from overheating or excessive current draw.

This component provides:

• Reliable compressor startup assistance

• Locked rotor protection to prevent motor damage

• Protection against overheating conditions

• Long-lasting PTC relay performance

• Compatibility with systems using or not using start capacitors

Correct relay and overload operation is critical because compressor startup places heavy electrical demand on refrigeration systems. A failed start device can prevent cooling entirely and may place unnecessary strain on the compressor.

Common Symptoms Indicating Replacement

A failing relay and overload assembly commonly causes:

• Refrigerator not cooling

• Compressor clicking on and off repeatedly

• Compressor attempts to start but shuts down

• Compressor overheating

• Refrigerator interior lights working but no cooling

• Intermittent compressor operation

• Audible clicking from rear compressor area

Replacing the URO81 often resolves these startup-related compressor failures when the compressor itself remains functional.

Compatibility Guidance

The URO81 is designed for:

• Refrigerators

• Light commercial refrigeration systems

• 115V compressor systems

• Compressors rated 1/12 to 1/5 HP

Before ordering, verify:

• Compressor voltage (115V)

• Horsepower range

• Push-on terminal configuration

• Appliance model compatibility

Improper relay sizing can cause startup failure or compressor damage. If unsure, Appliance Kingdom can help confirm compatibility before purchase.

Installation Overview

Replacing the URO81 is considered a moderate-to-advanced repair due to direct compressor electrical connections.

Installation typically involves:

• Disconnecting appliance power

• Accessing rear compressor compartment

• Removing failed relay/overload assembly

• Connecting URO81 to compressor terminals

• Verifying secure electrical connections

• Testing compressor startup

Because improper wiring can damage the compressor, professional installation is strongly recommended unless you have refrigeration repair experience.

Community repair discussions often stress confirming compressor health before replacing universal relay kits.
