Whirlpool Refrigerator: relay failure

Professional Repair Guide

What is this symptom?

Experiencing relay failure in your Whirlpool refrigerator can lead to frustrating cooling issues. If you hear repeated clicking and humming or the compressor fails to start, it may be due to a faulty start relay or overload relay. Addressing this issue promptly is crucial to prevent food spoilage.

Urgency: High

Important Tips for Whirlpool Models

Whirlpool start relay assemblies are often a combined module including start relay, overload, and capacitor; exact part varies by model.

Possible Causes

Faulty Start Relay / Start Device

How to Identify: Click–hum–off cycle from compressor; compressor not running though fans run; clicking sounds.

Part: Start relay assembly (start relay, overload, start capacitor)

Overload Relay Failure

How to Identify: Similar symptoms to start relay failure; buzzing then shutdown; testing with multimeter shows no continuity.

Part: Overload relay (part of start device assembly)

Start Capacitor Failure

How to Identify: Burnt smell at start device; compressor struggles to start then shuts off.

Part: Start capacitor (part of start device)

Compressor Internal Failure

How to Identify: If start device and overload test good but compressor still won’t run, possible compressor internal fault.

Part: Compressor

DIY Solutions

Replace Start Relay / Start Device

Moderate 30-60 minutes

Tools Needed: screwdriver, multimeter

Unplug refrigerator power to ensure safety.
Locate compressor start relay assembly on side of compressor.
Remove old relay assembly.
Use multimeter to test continuity of relay, overload, and capacitor if equipped.
Install new start relay assembly matching Whirlpool part.
Restore power and test compressor operation.

⚠️ Safety First: Always disconnect AC power before servicing compressor/start device.
