Ambient / room-temperature sensor fault

Unplug the refrigerator and locate the ambient sensor near the control housing or top hinge area
Measure the sensor resistance at room temperature and compare against the NTC expectation
Inspect the short wiring run to the board for damage or a loose connector
Reseat the connector and clean any corrosion on the pins
Replace the ambient sensor if it reads open or out of range
Pro Diagnostic Tip
The ambient sensor tunes defrost timing and anti-sweat heaters to room conditions. E5 rarely spoils food but can cause door sweating in a humid kitchen until corrected.
