F01 — Inlet thermistor defective (CleanSpeak models)

On GE CleanSpeak dryers, F01 (and F03) indicate the inlet thermistor (temperature sensor) is defective. GE's spec is roughly 47.6K-52.4K ohms at 77°F — replace the thermistor if it reads outside that range.

Keep using it?
Yes, with caution
DIY difficulty
Moderate

How to fix it

  1. Unplug the dryer.
  2. Locate the inlet thermistor (location varies by CleanSpeak model — check the tech sheet for this cabinet).
  3. Disconnect the thermistor and measure resistance at room temperature (about 77°F/25°C) — GE's spec is roughly 47.6K-52.4K ohms.
  4. Replace the thermistor if it reads outside that range, or open/shorted.
  5. If resistance is correct, inspect the harness for damage and reseat the connector.
  6. Reassemble, restore power, and run a cycle. If F01/F03 persists with a verified-good thermistor, have the control board checked.

Why it happens

Typical signs: F01 or F03 on display · No heat or inconsistent heat · Cycle stops early or won't complete · Sensor Dry cycles end prematurely

  • Inlet thermistor out of spec Resistance reads outside the 47.6K-52.4K ohm range at 77°F (room temp), or reads open/shorted.
  • Damaged or disconnected thermistor harness A loose connector or broken wire can produce the same reading as a failed sensor.
  • Corroded connector pins Moist laundry environments oxidize thermistor terminals over time.

Frequently asked questions

What does the F01 code mean on a GE dryer?

On GE CleanSpeak dryers, F01 (and F03) indicate the inlet thermistor (temperature sensor) is defective. GE's spec is roughly 47.6K-52.4K ohms at 77°F — replace the thermistor if it reads outside that range.

What causes the F01 code on a GE dryer?

Inlet thermistor out of spec: Resistance reads outside the 47.6K-52.4K ohm range at 77°F (room temp), or reads open/shorted. Damaged or disconnected thermistor harness: A loose connector or broken wire can produce the same reading as a failed sensor. Corroded connector pins: Moist laundry environments oxidize thermistor terminals over time.

Is it safe to keep using a GE dryer with a F01 error?

Yes, with caution. This is rated a moderate-severity fault.

How do I fix F01 on a GE dryer?

Unplug the dryer. Locate the inlet thermistor (location varies by CleanSpeak model — check the tech sheet for this cabinet). Disconnect the thermistor and measure resistance at room temperature (about 77°F/25°C) — GE's spec is roughly 47.6K-52.4K ohms.
