Refrigerator Not Cooling? Compressor 5304539722 – Fix Complete Cooling Failure Fast
A failed compressor is the most serious cause of a refrigerator that runs but won't cool — or won't run at all. In most Frigidaire and Electrolux top-mount refrigerators, the 5304539722 is an Embraco ESX55CBC G2 compressor that drives the entire refrigeration cycle. When it fails, the fridge loses all cooling — food spoils, the freezer warms, and the unit may run constantly or not start at all. ⚡ The compressor is the heart of the refrigeration system — when it goes, nothing else can compensate. Part 5304539722 is the genuine OEM Embraco replacement that restores full refrigeration capacity.
❓ Is This the Right Part?
This is the correct fix if ALL of the following are true:
- ✔ Fridge powers on — lights work and fans run
- ✔ Condenser coils are clean and airflow is unobstructed
- ✔ Start relay and overload protector have been tested or replaced
- ✔ ONLY problem is no cooling — compressor won't start, hums and clicks off, or runs but produces no cold

🔧 Common Symptoms
- Refrigerator runs but neither fridge nor freezer cools
- Compressor hums briefly then clicks off (overload tripping)
- Compressor won't start at all — completely silent
- Unit runs constantly but temperature keeps rising
- Loud clicking or buzzing from the back of the fridge
- Food spoiling faster than normal despite normal settings
✔ If these symptoms match, the compressor is the most likely failed component.
✔ Replacing this compressor restores the full refrigeration cycle immediately.

Always replace the start relay and overload protector when installing a new compressor. These low-cost components are often the actual cause of compressor failure — installing a new compressor on a bad relay will kill it again within weeks.
⚙️ Installation
Skill Level: ADVANCED — 2–4 hours. Refrigerant handling requires EPA 608 certification. Disconnect power and allow the system to depressurize before cutting refrigerant lines. Remove the old compressor, install the new unit, braze the refrigerant lines, pull a deep vacuum, and recharge with the correct refrigerant type and weight. Restore power and verify cooling within 24 hours.

💡 Pro Tip
Before ordering a compressor, remove the start relay from the compressor side terminal and shake it. If it rattles, it's failed. A bad relay causes the exact same symptoms as a dead compressor — clicking, humming, no cooling — at a fraction of the cost. Confirm the relay is good before committing to a compressor replacement.
