WP4387835 – Genuine OEM Whirlpool Refrigerator Overload Assembly

The WP4387835 is a Genuine OEM compressor protection and start relay kit designed for Whirlpool refrigerators. It includes the compressor relay, overload protector, and cover assembly, engineered to Whirlpool factory specifications for safe and reliable compressor startup performance.

This component is critical for refrigerator operation because it protects the compressor from electrical overload while helping it start correctly during each cooling cycle. Available from Appliance Kingdom with fast Canada-wide shipping, this OEM part is commonly used in Whirlpool, Kenmore, KitchenAid, Estate, and other Whirlpool-built refrigerator systems.

If your refrigerator is not starting, clicking repeatedly, or not cooling properly, a failing overload and relay assembly is one of the most common causes.

Function & Importance of WP4387835

The compressor overload assembly plays a key role in the refrigerator’s sealed system operation.

It is responsible for:

  • Safely starting the compressor motor

  • Protecting the compressor from overheating or electrical overload

  • Cutting power if excessive current is detected

  • Assisting the relay in energizing the compressor windings

Without a properly functioning overload assembly, the compressor may fail to start or shut down prematurely, affecting overall cooling performance.

OEM specification matters because compressor systems require precise electrical tolerance—incorrect resistance or timing can cause compressor stress or long-term damage.

Common Symptoms of a Failing Overload Assembly

If the WP4387835 is failing or degraded, you may notice:

  • Refrigerator not starting at all

  • Repeated clicking sound from the back of the fridge

  • Compressor tries to start but shuts off immediately

  • Refrigerator and freezer not cooling

  • Warm fridge even though interior lights and fans may still work

  • Intermittent cooling or cycling failure

These symptoms often indicate a compressor start issue, where the relay/overload is not properly energizing or protecting the compressor.

Replacing this part often restores normal compressor startup and cooling performance when the compressor itself is still healthy.

Compatibility Guidance

This overload and relay assembly is designed for Whirlpool refrigerator systems, including select models from:

  • Whirlpool

  • Kenmore (Whirlpool-built units)

  • KitchenAid

  • Estate

Before ordering, always verify your refrigerator’s full model number located inside the refrigerator compartment or behind the door gasket area.

Do not install without confirming compatibility, as compressor start components must match system specifications precisely.
