Frigidaire Dryer Error Code E14 — Thermistor Error
What this means
The E14 error on Frigidaire dryers means the thermistor (temperature sensor) is not sending valid temperature data to the control board. The thermistor monitors the drum exhaust temperature to regulate the heating element. If it fails, the dryer may overheat, not heat at all, or shut down as a safety precaution. This is a relatively common sensor failure in Frigidaire Affinity and similar models.
Step-by-step fix
4 stepsLocate the thermistor
Unplug the dryer. The thermistor is located on the blower housing near the blower wheel, typically accessible by removing the back panel of the dryer.
It's a small sensor with two wires — much smaller than the thermal fuse or high-limit thermostat.
Check the wiring
Inspect the two wires leading to the thermistor. Make sure the connectors are firmly seated and not corroded. Loose connections can cause intermittent E14 errors.
Dryer vibration is the most common cause of loose thermistor connections.
Test the thermistor resistance
Disconnect the thermistor wires. Set your multimeter to ohms and measure resistance across the two terminals. At room temperature (75°F), a good thermistor reads approximately 50,000 ohms (50k). An open or zero reading means it's failed.
The resistance should decrease if you warm the sensor with your hand — this confirms it's responding to temperature changes.
Replace the thermistor
Remove the single mounting screw, pull the old thermistor off the blower housing, and install the new one. Reconnect the wires and run a timed dry cycle to verify the error clears.
The thermistor is one of the cheapest parts in the dryer — typically under $15.
When to call a professional
If replacing the thermistor doesn't fix the error, the control board's thermistor input circuit may be damaged. This requires board-level repair or replacement.
