Frigidaire Refrigerator Error Code Eg

The Eg error code on a Frigidaire refrigerator indicates a water supply fault detected by the ice maker system. Specifically, the control board monitors the ice sensor temperature immediately after a water fill cycle. Under normal operation, the incoming water causes a measurable temperature change at the ice sensor within 5 minutes of the water supply valve opening. When that temperature rise does not occur within the expected window, the board logs the Eg fault and halts normal ice production until the condition is resolved.

The two primary systems involved are the water supply path and the ice compartment temperature sensor. The water inlet valve, supply line, and household water pressure all affect whether water actually enters the ice maker tray during the fill cycle. If water flow is restricted, blocked, or absent entirely, the sensor will detect no thermal change and trigger the error. A faulty or out-of-calibration ice sensor can produce the same result even when water delivery is functioning correctly, because the board relies entirely on that sensor reading to confirm a successful fill.

Common root causes include a kinked or frozen water supply line, a failed water inlet valve solenoid, low household water pressure, or a defective ice sensor. In freezer environments, the supply line can freeze solid, completely blocking water flow. The ice sensor itself may drift out of range or fail entirely, sending incorrect temperature data to the control board regardless of actual fill activity.
