Refrigerator Not Cooling At All? Compressor W11557671 – Fix Complete Cooling Failure on JennAir & KitchenAid Fast
If your JennAir or KitchenAid refrigerator has completely stopped cooling — fridge and freezer both warming up, compressor not running or running but not pumping — a failed compressor is the most likely cause. In JennAir, KitchenAid, and Whirlpool-platform refrigerators, the compressor is the heart of the sealed cooling system, pressurizing refrigerant to drive the entire cooling cycle. When it fails, the refrigerant circuit stops circulating entirely — both the fridge and freezer compartments warm to room temperature and no amount of thermostat adjustment will restore cooling. ⚡ The W11557671 compressor is the OEM-specified replacement for a wide range of premium JennAir and KitchenAid built-in and counter-depth refrigerators. Part W11557671 is the genuine OEM compressor that restores full sealed-system operation and brings your refrigerator back to factory cooling performance.
❓ Is This the Right Part?
This is the correct fix if ALL of the following are true:
- ✔ Refrigerator powers on — lights, display, and fans work normally
- ✔ Compressor is not running, or runs briefly then shuts off on overload
- ✔ Refrigerant charge has been confirmed present (no leak) by a certified technician
- ✔ Both fridge and freezer compartments are warming — complete cooling failure, not partial

🔧 Common Symptoms
- Refrigerator completely warm — fridge and freezer both at room temperature
- Compressor clicks on then immediately shuts off (overload protector tripping)
- Compressor hums but does not start — seized or failed start components
- No cooling after confirmed refrigerant charge — compressor not pumping
✔ If these symptoms match and refrigerant charge is confirmed, the compressor is the correct repair.
✔ Replacing this compressor with the OEM W11557671 restores full sealed-system operation and factory cooling performance.

When replacing a compressor, always replace the compressor start relay and overload protector at the same time — these low-cost components are often stressed or damaged by a failing compressor and are a common cause of repeat failures. Also flush and recharge the refrigerant system with fresh refrigerant and a new filter drier to protect the new compressor.
⚙️ Installation
Skill Level: ADVANCED — Requires EPA 608 Certification. Professional installation strongly recommended. Disconnect power and allow the refrigerator to fully defrost before servicing. Compressor replacement requires recovery of existing refrigerant, brazing the new compressor into the sealed system, deep evacuation, and recharge with the correct refrigerant type and weight — this work must be performed by an EPA 608-certified technician. Improper installation will void the compressor warranty and can damage the sealed system.

💡 Pro Tip
Before committing to a compressor replacement, remove and shake the start relay (plugged into the side of the compressor). If it rattles, the relay has failed — replace it first. A bad start relay mimics compressor failure and costs $15 vs. $600+. If the relay is good and the compressor still won’t start, then the compressor itself has failed and W11557671 is your fix.
