Real Case from Largo: LG French Door Fridge, Fridge Warm Again After Defrost

We were recently called to Largo, Florida to diagnose an LG French Door Refrigerator. The homeowner reported:

Fridge temperature climbing above 50°F
Freezer seemed fine for a few days, then food started thawing
Ice buildup behind the freezer panel
Strange “crackling” sound before it warmed up
No cooling, no airflow

Initial assumption? Compressor failure.

But with proper diagnostics, we found the defrost heater circuit had failed — a much more affordable repair!

🧰 Step-by-Step Diagnosis – What We Did

Step	What We Checked	What We Found
✅ Measured temps	Fridge at 55°F	Not safe for food
✅ Pulled freezer panel	Thick frost on evaporator	Airflow blocked
✅ Tested defrost heater	Open circuit – heater failed	Needed replacement
✅ Tested defrost sensor & fuse	Thermostat out of range	Replaced
✅ Inspected control board	Sending correct voltage	No replacement needed

⚒️ Repair Completed

We replaced:

✅ Defrost Heater (OEM LG)
✅ Defrost Bi-Metal Thermostat
✅ Cleared frost and reassembled system
✅ Verified system went into defrost cycle

Total repair time: Same Day

🧠 What Causes LG Defrost System Failures?

LG refrigerators rely on timed defrost cycles to melt frost from the evaporator coils. If this system fails, frost builds up, blocking airflow, and the fridge appears to “stop cooling.”

Common causes:

Burned-out defrost heater
Defective defrost thermostat
Faulty control board not initiating defrost
Frozen drain line backing up
