SPP5 - Univeral Supco Refrigerator Hard Start, Relay & Start Capacitor Combo

SPP5 – Universal Supco Refrigerator Hard Start, Relay & Start Capacitor Combo

The Supco SPP5 Hard Start Relay & Capacitor Kit is a high-quality universal aftermarket refrigerator compressor start-assist kit designed to help hard-starting refrigeration compressors restart efficiently. This universal Supco hard start relay and start capacitor combination is commonly used as a replacement solution for refrigerators experiencing compressor startup difficulty due to weak starting torque, low voltage conditions, or aging compressor performance.

Designed for refrigeration and single-phase compressor applications, the SPP5 combines a relay and start capacitor into a compact two-wire installation kit that helps increase compressor starting torque by up to 300%, helping restore dependable refrigerator cooling performance. It is available from Appliance Kingdom with fast Canada-wide shipping for homeowners, landlords, and professional appliance repair technicians.

What Does the SPP5 Hard Start Kit Do?

The SPP5 provides additional starting torque to a refrigerator compressor during startup. It temporarily boosts electrical assistance during compressor ignition, helping the motor overcome hard-start conditions more effectively.

This is especially useful for compressors experiencing:

• Hard starting due to wear or age

• Low voltage supply issues

• Delayed compressor startup

• Clicking relays without compressor engagement

• Compressor overload tripping

By supplying extra startup assistance, the SPP5 helps compressors start faster and reduces startup stress under difficult operating conditions. The integrated relay automatically removes the capacitor from the circuit once startup is complete for safe operation.

Common Symptoms That May Indicate Replacement

A failing refrigerator compressor start system may cause:

• Refrigerator not cooling properly

• Compressor clicking but not starting

• Repeated compressor short cycling

• Warm refrigerator compartment

• Compressor hums but does not engage

• Intermittent cooling loss

• Overload protector repeatedly tripping

• Delayed compressor startup after power cycles

If these symptoms are caused by weak starting assistance, installing the SPP5 can often restore reliable compressor startup and improve cooling performance.

Compatibility Guidance

The SPP5 is a universal hard start kit designed for compatible single-phase refrigeration compressors.

Before ordering:

• Verify your appliance uses a compatible single-phase compressor

• Confirm voltage compatibility

• Ensure your compressor falls within supported operating ranges

Because universal start kits are application-specific, compatibility should always be verified before installation. Appliance Kingdom support can assist with compatibility confirmation before purchase.

Installation Overview

Installing the SPP5 is generally considered a moderate electrical appliance repair.

Installation typically involves:

• Disconnecting appliance power

• Accessing compressor electrical terminals

• Connecting the two-wire hard start kit across designated terminals

• Securing the device upright
