What Does Error F23 Mean?
The Kenmore Dryer F23 error indicates a failure in the outlet thermistor, which monitors the exhaust temperature. This may result in the dryer stopping mid-cycle, a lack of heat during drying, and laundry not drying completely. Addressing this issue typically involves checking for a faulty thermistor or loose wiring connections.
Common Symptoms:
- Dryer stops mid‑cycle and displays error code F23 shortly after starting.
- No or reduced heat during a drying cycle.
- Dry laundry not drying fully.
- Dryer may run briefly then shut off with F23 displayed.
Possible Causes
- Faulty or shorted outlet thermistor (temperature sensor) (high)
- Loose or damaged wiring/harness to the outlet thermistor (medium)
- Incorrect thermistor resistance at room temperature (medium)
How to Fix Error F23
DIY Fix Basic User Checks Before Repair
- Unplug the dryer from power to ensure safety before any inspection.
- Check that the dryer is getting proper electrical supply and that the plug is fully seated.
- Remove lint from the lint trap and ensure vents are not blocked, which can indirectly affect temperature regulation.
Technician Only Diagnose and Replace Outlet Thermistor
- Disconnect power to the dryer and access the thermistor location (typically on the blower housing near the heating element).
- Use a multimeter to measure resistance across the thermistor; verify expected resistance (~10,000 ohms at room temperature).
- Inspect wiring harness and connectors for damage or poor connections; repair or replace as needed.
- Replace the thermistor if resistance is out of range or if the component fails continuity tests.
- Reassemble the dryer, restore power, and test for proper operation without error codes.
Parts needed: Outlet thermistor (temperature sensor), Multimeter for testing, Replacement wiring/connectors if needed
- If multimeter resistance readings are inconclusive or you are uncomfortable measuring electrical components.
- If wiring harness or connectors appear damaged beyond simple repair.
- If replacing the thermistor does not clear the F23 error code, suggesting deeper control board or sensor circuit issues.
