URSC10 - Universal Supco Refrigerator Hard Start, Relay & Start Capacitor Combo

URSC10 – Universal Supco Refrigerator Hard Start, Relay & Start Capacitor Combo

The URSC10 is a high-quality universal replacement hard start kit engineered by Supco for refrigerator and freezer compressor starting systems. Designed for domestic and commercial refrigeration applications, this universal relay and start capacitor combination helps restore reliable compressor startup performance in systems experiencing hard-start conditions, voltage-related startup issues, or relay failure. It is rated for 115V compressors from 1/20 HP to 1/2 HP and supports RSIR, CSIR, PSC, and CSR compressor systems.

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

What Does the URSC10 Hard Start Kit Do?

The URSC10 combines a start relay and hard start capacitor into one compact assembly to provide the extra starting torque needed to help a refrigerator compressor start efficiently.

Its primary functions include:

• Delivering a temporary electrical boost during startup

• Assisting compressors with hard-start conditions

• Reducing startup strain caused by voltage fluctuations

• Replacing failed or weak current-type relays

• Supporting smoother compressor engagement

Because refrigeration compressors rely on precise startup sequencing, using a properly rated replacement helps protect compressor life and improve system reliability.

Why OEM-Level Quality Matters

Hard-start components operate under repeated electrical stress every time the refrigerator compressor cycles on.

A properly engineered replacement like the URSC10 helps ensure:

• Reliable startup performance

• Correct capacitor discharge timing

• Reduced electrical stress on compressor windings

• Protection against repeated startup failures

• Longer compressor operating life

Low-quality replacements may fail prematurely or create inconsistent compressor performance.

Common Symptoms Indicating Replacement

A failing refrigerator start relay or capacitor often causes:

• Refrigerator not cooling properly

• Compressor clicking but not starting

• Repeated clicking sounds near compressor

• Compressor attempts to start then shuts off

• Intermittent cooling loss

• Compressor overheating

• Refrigerator runs warm while lights and fans still work

Replacing the URSC10 can often resolve startup-related cooling failures when the compressor itself remains functional.

Compatibility Guidance

The URSC10 is compatible with:

• Refrigerators

• Freezers

• Domestic refrigeration systems

• Commercial refrigeration systems

Supported compressor types:

• RSIR

• CSIR

• PSC

• CSR

Rated for:

• 115V

• 1/20 HP to 1/2 HP compressors

Always verify compressor voltage and horsepower specifications before ordering to ensure compatibility.
