Dcs Refrigerator Error Code AMBIENT TEMPERATURE SENSOR

This error means the control board is receiving a signal from the ambient temperature sensor that falls outside the valid range, specifically above 149°F or below -58°F. Since those temperatures are not realistic for any normal environment, the fault almost always points to a physical problem with the sensor, its wiring, or its connector rather than an actual temperature extreme. The refrigerator displays this code to alert you that the sensor circuit needs inspection and correction.

The refrigerator may not maintain proper temperatures reliably while this fault is active, since the control system depends on sensor feedback to regulate cooling. Monitor interior temperatures with a separate thermometer and, if cooling has been compromised for more than two hours, follow standard food safety guidelines for perishables. Address the error as soon as possible to restore normal operation.

A power reset may temporarily clear the error code, but if the underlying fault in the sensor, wiring, or connector has not been corrected, the code will return once the control board reads the out-of-range signal again. A permanent fix requires identifying and resolving the root cause, whether that is a loose connector, a displaced sensor housing, damaged wiring, or a failed sensor.

Some causes are straightforward to address without professional help. Checking that the sensor housing is properly seated and that all wiring connectors are firmly attached requires no special tools. If the wiring is visibly damaged or the sensor tests as defective with a multimeter, replacing the sensor or repairing the wiring is a more involved repair that some experienced DIYers can handle, though a technician may be preferable for wiring repairs.

If the fix is simply reseating the sensor or reconnecting a loose wire, there may be little to no parts cost, though a service call typically runs between $75 and $150 for labor. If the sensor itself has failed and needs replacement, parts and labor combined generally range from $100 to $300 depending on the part cost and local labor rates. Wiring repairs that involve cutting and splicing may add additional labor time.
