Error Code F-1-ô

Q: What does error code F-1-ô mean on a Samsung refrigerators?

Outside temperature sensor is not reporting correctly Sensor housing separation; Connector contact error; Sensor disconnection or open; Short circuit in sensor wiring; Temperature sensing out of valid range (>149°F or <-58°F)

Q: What should I check first for error code F-1-ô?

Check inside top hinge for water or corrosion

Outside temperature sensor is not reporting correctly

Moderate

Address soon - your appliance may not work properly

Also displayed as: F-1-ô

What This Means

Sensor housing separation; Connector contact error; Sensor disconnection or open; Short circuit in sensor wiring; Temperature sensing out of valid range (>149°F or <-58°F)

What actually causes this:

Sensor got wet or connector corroded

First Thing to Check

Check inside top hinge for water or corrosion

Parts Involved

Ambient Sensor (502AT Thermistor) - mounted in right top table of upper hinge
