UPRO81 - Genuine OEM Supco Refrigerator Relay & Overload

UPRO81 – Genuine OEM Supco Refrigerator Relay & Overload

The UPRO81 is a genuine OEM-quality Supco Universal Pro Push-On Relay & Overload designed for refrigerator compressor start systems. This refrigerator relay and overload combination is engineered to restore compressor start-up performance and protect refrigeration systems from electrical overload conditions.

Designed for domestic and light commercial refrigerators operating on 115V systems with compressor ratings from 1/12 to 1/5 HP, the UPRO81 provides reliable compressor starting assistance while protecting the compressor windings from overheating and locked rotor damage. This replacement component commonly resolves refrigerator no-cool conditions caused by failed compressor start relays or overload protectors.

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

What Does the UPRO81 Relay & Overload Do?

The UPRO81 relay and overload assembly controls compressor start-up and protects the refrigerator compressor during operation.

Its two essential functions are:

• Start Relay Function: Delivers the electrical boost required to start the refrigerator compressor

• Overload Protection: Prevents compressor damage by disconnecting power during overheating or excessive current draw

The UPRO81 features a safe, long-lasting PTC relay design with locked rotor protection, helping prevent start winding overheating and extending compressor life. It is compatible with refrigeration systems with or without start capacitors.

Correct OEM-quality specifications are critical because improper relay performance can cause compressor damage, hard starts, repeated clicking, or total cooling failure.

Common Symptoms Indicating Relay & Overload Replacement

A failed refrigerator relay or overload protector often causes:

• Refrigerator not cooling

• Compressor clicking repeatedly

• Compressor fails to start

• Refrigerator cycles on and off abnormally

• Warm freezer and fresh food sections

• Intermittent cooling loss

• Compressor humming but not engaging

• Overheating compressor shutdown

If the compressor itself tests good but fails to start properly, replacing the UPRO81 can often restore normal cooling operation.

Compatibility Guidance

The UPRO81 is designed for:

• Refrigerators

• Domestic refrigeration compressors

• Light commercial refrigeration systems

• 115V compressor applications

• 1/12 to 1/5 HP compressors

Before ordering, verify:

• Appliance model number

• Compressor horsepower rating

• Voltage requirements

• Terminal configuration compatibility

Because relay sizing is based on compressor horsepower and continuous running amperage, confirming specifications before ordering is strongly recommended.

If you need compatibility confirmation, the support team at Appliance Kingdom can help verify fitment.

Installation Overview

Replacing a refrigerator relay and overload is generally considered a moderate repair.

Typical installation involves:

• Disconnecting refrigerator power

• Accessing the compressor compartment

• Removing the failed relay/overload assembly

• Installing the UPRO81 onto compressor terminals

• Verifying secure electrical connections

• Restoring power and testing compressor operation

Experienced DIY users may complete installation safely.

Because this repair involves live electrical components and compressor terminals, professional installation is recommended if you are unfamiliar with appliance electrical systems.
