Refrigerator - Explanation Of Red or Orange Glow

In a frost-free (no-frost) Refrigerator, the defrost system activates defrost heaters in the evaporator section in the rear of Freezer compartment that heat up and melt frost off of the evaporator coils. This process lasts for approximately 25 to 45 minutes and usually happens up to twice a day.
