🧊 Refrigerator compressor runs constantly

⚠️ Common Causes

Door seal worn, evaporator fan failing, defrost system failed, low refrigerant

🔧 Parts to Check

• Door gaskets
• Evaporator fan
• Defrost heater/timer
• Refrigerant level

🔧 Troubleshooting Steps

1. Check door seals: close door on dollar bill — should not slide out easily
2. Check evaporator fan: listen for fan running when compressor runs
3. Check defrost system: evaporator coils should not be completely iced over
4. Check interior temp: 35-38°F (fridge) and 0-5°F (freezer)
5. If warm AND compressor runs constantly = likely low refrigerant (professional needed)
