Dcs Refrigerator Error Code F-SENSOR

The F-SENSOR code indicates a fault with the fresh food compartment temperature sensor. It activates when the sensor reports a temperature above 149°F or below -58°F, values that signal a sensor or wiring problem rather than an actual temperature extreme. Possible causes include a sensor that has slipped out of its housing, a wiring short or cut, a contact failure at the connector, or a defective sensor.

A reset may temporarily clear the displayed code, but the error will return if the underlying problem has not been corrected. The fault is triggered by an out-of-range sensor reading, so the code will reappear as long as the sensor, wiring, or connection issue remains unresolved. Address the root cause before relying on a reset.

If the fix is simply reseating the sensor or connector, there may be no parts cost, though a service call fee will still apply. If the sensor itself needs replacement, parts typically range from $20 to $80 depending on the model, with total repair costs including labor generally falling between $100 and $250. Wiring harness repairs can vary depending on the extent of the damage.

Start by locating the F-Room sensor in the fresh food compartment and confirming it is fully seated in its housing. Check the wiring connector for loose or corroded pins and reseat it firmly. Inspect the sensor wiring along its entire length for cuts, pinching, or shorts. If the wiring and connections are all intact, the sensor itself is likely defective and will need to be replaced.

Continuing to run the refrigerator with an active F-SENSOR fault is not recommended. Without an accurate temperature reading from the fresh food compartment, the control board cannot properly regulate cooling, which puts food safety at risk. Address the issue promptly to restore proper temperature monitoring and control.
