Fisher & Paykel Dryer Error Code H71 — Thermistor / Temperature Sensor Fault
What this means
Error code H71 on Fisher & Paykel dryers indicates the thermistor (temperature sensor) is providing readings outside the acceptable range. The dryer uses an NTC thermistor to monitor drum temperature throughout the drying cycle. If the sensor is disconnected, short-circuited, or has drifted out of calibration, the control board cannot regulate the heating element safely and will shut down the dryer. This code is common on Fisher & Paykel condensing and heat pump dryer models.
Alternate codes: Error H71, Fault H71
Step-by-step fix
4 stepsPower cycle the dryer
Unplug the dryer or turn off the circuit breaker. Wait 5 minutes and restore power. Start a new drying cycle. A temporary electrical glitch can trigger a false H71 code.
If H71 appears intermittently (not every cycle), suspect a loose wiring connection rather than a fully failed sensor.
Locate and test the thermistor
Unplug the dryer. Remove the rear panel or top panel (varies by model) to access the drum area. The thermistor is typically located near the exhaust duct or inside the drum housing. Disconnect its wiring and measure resistance — at room temperature it should read approximately 10,000–12,000 ohms. Zero or infinite resistance confirms a failed sensor.
Fisher & Paykel dryers may have two thermistors — one for the drum and one for the condenser (on condensing models). Test both.
Check wiring connections
Inspect the wiring between the thermistor and the control board. Look for loose connectors, frayed wires, or corroded terminals. The vibration from the dryer drum can loosen connections over time.
Gently tug each wire at its connector to check for cold solder joints or wires that pull out easily.
Replace the thermistor
If the sensor reads out of range, remove it (usually held by one or two screws) and install the replacement. Reconnect the wiring and reassemble the panel. Run a test cycle to confirm the error clears.
When installing the new thermistor, ensure it sits flush against the mounting surface for accurate temperature readings.
When to call a professional
If both thermistors test fine but H71 persists, the control board's temperature input circuit may be faulty. A technician can perform board-level diagnostics.
