PO115 - Universal Supco Refrigerator Relay

PO115 – Universal Supco Refrigerator Relay (Genuine OEM Replacement Style)

The PO115 is a Universal Supco Refrigerator Push-On Relay designed for compressor start control in 115V refrigeration systems. This part is commonly used in refrigerators to help the compressor start and operate correctly by managing the electrical starting sequence.

The PO115 is a universal compressor start relay rated for 1/12 to 1/2 HP refrigeration systems and 115V operation. It is widely used as a replacement-style solution for failed OEM refrigerator start relays in Whirlpool and other major refrigerator brands. It is available in Canada through Appliance Kingdom with fast nationwide shipping.

What the PO115 Refrigerator Relay Does

The compressor relay is a critical electrical component that helps start the refrigerator’s compressor. When the refrigerator turns on, the relay temporarily powers the compressor start winding, allowing the motor to begin spinning. Once the compressor reaches running speed, the relay disengages the start circuit.

The PO115 Supco relay is designed for:

• Starting the refrigerator compressor safely and efficiently

• Supporting pin-type compressor terminals (push-on style)

• Working with or without a start capacitor

• Replacing multiple OEM relay designs with one universal unit

Because it is a universal design, it is commonly used in refrigerator repair situations where the original relay has failed or is no longer available.

Why This Part Is Important

The compressor is the heart of the refrigerator cooling system. Without a properly functioning relay:

• The compressor may not start at all

• The refrigerator will not cool

• The system may click repeatedly without running

• The compressor may overheat due to failed start attempts

Using a properly rated relay like the PO115 ensures the compressor receives the correct starting power without damage, improving reliability and extending system life.

Common Symptoms of a Faulty Refrigerator Relay

A failing or damaged compressor relay often causes:

• Refrigerator not cooling or staying warm

• Repeated clicking noise from the compressor area

• Compressor trying to start but shutting off immediately

• Intermittent cooling performance

• Buzzing or humming near the compressor

• Refrigerator completely dead but lights still working

If these symptoms are present, replacing the relay is one of the most common and cost-effective first repair steps.

Compatibility Guidance

The PO115 is a universal compressor relay designed for:

• 115V residential refrigerators

• Compressors rated between 1/12 HP and 1/2 HP

• Pin-type compressor terminal systems

Always verify your refrigerator model number and compressor specifications before ordering to ensure correct fit and electrical rating compatibility.
