Step-by-step fix
3 stepsCheck for ice buildup
Open the freezer and look for unusual ice accumulation on the back wall or around the evaporator fan area. Excessive frost indicates the defrost system isn't working.
If the back wall of the freezer is a solid sheet of ice, the defrost system has definitely failed.
Manually defrost if needed
If there's heavy ice buildup, unplug the refrigerator and leave the doors open for 6–8 hours to fully defrost. Place towels under the unit to catch meltwater.
You can speed up defrosting with a hair dryer on low heat — never use sharp tools to chip ice.
Power cycle and monitor
After defrosting, plug the refrigerator back in. If the error returns within 24–48 hours, the defrost sensor needs replacement.
The defrost sensor is located behind the back panel inside the freezer, near the evaporator coils.
When to call a professional
Replacing the defrost sensor involves removing the freezer's rear panel and working near the evaporator coils. If you're not comfortable with this, call a technician.
