Display shows E8 and the refrigerator may not cool properly or may run continuously.

Safety first: Unplug the refrigerator before accessing the control panel or toe grille.

Locate the ambient sensor:

• On many models, the ambient sensor is near the front bottom grille or behind the control panel.
• Remove the relevant cover and look for a small probe-type sensor.

Inspection:

• Check for dust buildup, physical damage, or dislodged mounting.
• Reseat the connector and ensure the sensor is not touching hot components.

Test and replace:

• If you can measure resistance, compare to the service chart at room temperature.
• Replace the sensor if readings are out of range or if E8 persists after reseating.

Note: Incorrect ambient readings can cause the unit to over- or under-cool. If a new sensor does not resolve E8, the control board may be misreading the input.
