PRO41 - Universal Supco Refrigerator Relay & Overload

PRO41 – Universal Supco Refrigerator Relay & Overload

The PRO41 is a high-quality universal aftermarket refrigerator compressor start relay and overload combination designed by Supco for refrigerator compressor applications. Engineered for 115V systems with 1/4 to 1/3 HP compressors, the PRO41 is designed to replace failed compressor relay and overload assemblies in compatible domestic and light commercial refrigerators.

Available from Appliance Kingdom with fast Canada-wide shipping, this universal compressor starting device is commonly used by appliance repair technicians and experienced DIY users to restore refrigerator compressor startup performance when original relay components fail.

A failed compressor relay or overload often causes clicking noises, compressor startup failure, intermittent cooling loss, or repeated compressor shutdown. Replacing the faulty start device with the PRO41 can often restore proper refrigerator cooling performance when the compressor itself is still functional.

What Does the PRO41 Relay & Overload Do?

The PRO41 combines two critical refrigerator compressor starting components into one assembly:

• Start relay: Delivers power to help start the compressor motor

• Overload protector: Prevents compressor overheating and protects against locked rotor damage

This combination helps ensure smooth compressor startup while protecting internal compressor windings from electrical overload or thermal damage.

The PRO41 is manufactured to strict performance standards and includes:

• Locked rotor protection

• Push-on pin-type terminal installation

• UL-recognised construction

• Compatibility with compressors using or not using a start capacitor

Correct relay and overload specifications are essential for compressor longevity and safe refrigerator operation. Using the wrong start device can cause repeated hard starts, overheating, or compressor failure.

Common Symptoms Indicating Replacement

A failing refrigerator relay and overload can cause several cooling problems, including:

• Refrigerator not cooling

• Compressor clicks repeatedly but does not start

• Intermittent cooling loss

• Compressor shuts off shortly after startup

• Warm refrigerator and freezer compartments

• Burning smell near compressor area

• Compressor hums briefly then clicks off

If the compressor windings test good and the relay/overload assembly is faulty, replacing the PRO41 often restores normal cooling performance.

Compatibility Guidance

The PRO41 is designed for:

• Refrigerators

• Light commercial refrigeration units

• Compatible 115V compressors rated 1/4 to 1/3 HP

Before ordering, verify:

• Compressor voltage rating

• Compressor horsepower

• Pin-type terminal configuration

• Appliance model specifications

Because this is a universal replacement component, proper electrical matching is critical.

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