Refrigerator Not Cooling? Start Relay W11547180 – Fix Compressor Failure Fast
If your Whirlpool refrigerator won't cool and you hear repeated clicking from the back, the start relay is the most common cause. In most Whirlpool-family refrigerators, this is caused by a failed PTC start relay. When it fails, the compressor receives no startup current and the fridge warms up completely — food spoils within hours. ⚡ Common failure point in Whirlpool-built refrigerators. Part W11547180 is the genuine OEM replacement that restores compressor startup and full cooling immediately.
❓ Is This the Right Part?
This is the correct fix if ALL of the following are true:
- ✔ Appliance powers on — lights, display, and fans work normally
- ✔ Freezer and fridge compartments are both warming up
- ✔ Power supply and outlet confirmed OK
- ✔ ONLY problem is compressor won't start — clicking sound every few minutes from rear of fridge

🔧 Common Symptoms
- Refrigerator not cooling or warming up
- Compressor clicks repeatedly then shuts off (every 2–5 minutes)
- Freezer not freezing — ice melting
- Rattling or buzzing noise from back lower panel
- Compressor runs briefly then stops
✔ If these symptoms match, this is the most likely failed component in the system.
✔ In most cases, replacing this start relay restores normal cooling operation immediately.

⚠️ Recommended While Repairing:
Check and replace the Compressor Overload Protector at the same time — it sits on the same compressor terminal block and a failed overload mimics start relay symptoms exactly. Replacing both together costs less than a second service call and takes zero extra time since the compressor is already exposed.

⚙️ Installation
Skill Level: EASY — 15–20 minutes. Disconnect power before servicing. Pull the fridge away from the wall and remove the lower rear access panel to expose the compressor. The start relay plugs directly onto the side terminal pins of the compressor — pull the old relay straight off, shake it to confirm the rattle, and firmly plug the new W11547180 onto the same terminals. Reinstall the panel, restore power, and allow 24 hours for the fridge to return to full operating temperature.

💡 Pro Tip
Rattle Test Before You Order:
Shake your existing start relay — if you hear a rattle, the PTC element inside has cracked and the relay has definitely failed. No rattle doesn't fully clear it, but a rattle is a definitive diagnosis. While you have the rear panel off, also inspect the condenser coils for dust buildup — clogged coils force the compressor to overwork and can cause premature relay failure again within months.
