Fisher & Paykel Dryers F2 Error: Exhaust thermistor fault
Fisher & Paykel dryer error code F2 is a mid-severity fault meaning Exhaust air thermistor fault. The dryer can be used briefly in a supervised timed-dry setting while you arrange repair, but do not use auto-dry cycles — the fault disables the sensor used to terminate.

Answer to continue safely
Is it safe to keep using?
Maybe. The dryer can be used briefly in a supervised timed-dry setting while you arrange repair, but do not use auto-dry cycles — the fault disables the sensor used to terminate drying, so over-drying or overheating is possible. Never leave the dryer running unattended.
Can I reset the code?
Yes. Power-cycling will clear a transient F2 fault. If the code returns after one cycle, the thermistor or exhaust ducting requires physical attention before the dryer can operate reliably.
When to stop immediately?
Stop if you notice: Burning smell or scorch marks are present near the exhaust area, Code returns within the first few minutes of every cycle.
Symptoms You May Notice
F2 shown on display
The panel displays F2 and the dryer may stop mid-cycle or refuse to start a new one until the fault is cleared.
Auto-dry cycles end too early
The exhaust thermistor is used on some models to infer load dryness. A fault causes premature cycle termination, leaving clothes damp.
Dryer runs without heating
In safe-mode operation the heating circuit may be disabled, tumbling clothes in unheated air.
Possible Causes
Failed exhaust thermistor
The NTC sensor in the exhaust duct has failed, returning an out-of-range resistance to the control board.
DIY PossibleLint accumulation around sensor
Heavy lint deposits on the sensor body insulate it thermally, causing it to misread exhaust temperature.
DIY PossibleLoose harness connector
Vibration over time has loosened the sensor connector at the board or at the sensor itself.
DIY PossiblePartially blocked exhaust duct
Restricted airflow alters exhaust temperature profiles, potentially pushing readings outside the sensor's mapped range.
DIY PossibleSafe Checks You Can Do
-
1
Power-cycle the dryer
Unplug the dryer for 5 minutes, restore power, and attempt a short cycle to check whether F2 clears.
Note whether the code appears immediately at startup or only after the dryer runs for several minutes — this distinguishes a hard failure from a thermal-drift fault.
-
2
Clean lint filter and exhaust path
Remove and clean the lint filter. Disconnect the exhaust duct at the wall and check for lint clogs along the entire run, including bends and the wall cap flap.
Fisher & Paykel recommends cleaning the exhaust duct at least once per year. A blocked duct can cause exhaust temperatures to exceed the sensor's readable range.

3
Inspect and clean the exhaust thermistor
After unplugging, access the exhaust duct sensor (typically near the blower housing on the rear panel) and carefully brush away any lint from around the sensor tip. Reseat the connector.
Do not use water to clean the sensor body — use dry compressed air or a soft brush.

Test thermistor resistance
Disconnect the thermistor and measure resistance across its terminals with a multimeter. A reading of open circuit (OL) or near zero confirms sensor failure. Replace with a Fisher & Paykel compatible NTC thermistor for your model series.
Match the thermistor resistance value to the service specification — substituting a generic thermistor with the wrong resistance curve will cause persistent fault codes.
Tools required
When to Call a Professional
Contact a qualified technician if:
- Thermistor location requires removing the blower assembly for access
- Code persists after thermistor replacement (board fault suspected)
- Exhaust duct runs through walls and cannot be self-serviced
