Common Refrigerator Problems We Repair

  • Refrigerator not cooling: Usually caused by dirty condenser coils, a failed evaporator fan, or a faulty compressor.

  • Leaking water: Commonly due to a clogged defrost drain or cracked water supply line.
  • Excessive frost buildup: Points to a compromised door gasket seal or a broken defrost heater.
  • Making unusual noises: Buzzing, clicking, or grinding sounds suggest failing fans or compressor relays.

Refrigerator Repair FAQs

Why is my refrigerator running constantly but not cooling?

This is often caused by dirty condenser coils that restrict heat transfer, or a failing evaporator fan. When the fridge cannot properly disperse heat, the compressor runs non-stop trying to reach the set temperature.

Why is water leaking onto my kitchen floor?

A blocked defrost drain is the most common culprit. When the defrost cycle runs, water has nowhere to go and overflows the drain pan. It can also be a cracked water supply line leading to the ice maker.

Is a built-in refrigerator worth repairing?

Almost always. Built-in units like Sub-Zero or Thermador represent a significant investment and are designed for longevity. Repairing a compressor or sealed system is highly cost-effective compared to replacing a $10,000+ unit.
