Kenmore Washer Error Code F/24

F/24 means the washer's water temperature sensor (NTC thermistor) is reading a value outside the acceptable range of 23°F to 217°F (-5°C to 103°C) during the heating step of the wash cycle. The control board cannot confirm a valid temperature reading, so it stops the cycle and displays the fault code. The issue is most often caused by a failed sensor, a loose connector, or damaged wiring.

You should not continue running the washer while this code is active. The control board halts the heating step specifically because it cannot verify water temperature, which means the washer may not clean properly and could potentially allow unsafe temperature conditions. Resolve the fault before resuming normal use.

Unplugging the washer for a few minutes may temporarily clear the code, but if the underlying sensor or wiring fault still exists, the error will return as soon as the machine reaches the heating step again. A reset is useful for confirming whether the fault is intermittent, but it does not fix the root cause. The sensor and its wiring should be inspected and tested to resolve the issue permanently.

Yes, in many cases this is a DIY-friendly repair. Start by unplugging the washer, then inspect the temperature sensor connector and wiring for visible damage, corrosion, or loose pins. If the wiring looks intact, use a multimeter to test the resistance of the NTC thermistor. If the sensor is out of spec, replacing it is a relatively straightforward part swap on most Kenmore washer models.

If only the wiring or connector needs attention, the repair may cost little to nothing beyond your time. A replacement NTC water temperature sensor typically costs between $15 and $50 for the part itself. If a professional technician is needed, expect to pay between $100 and $250 total depending on your location and the labor involved.
