Dryer displays E14 and may not heat properly, often on heat pump or condensing models

Safety first: Disconnect power before accessing sensors or control boards.

• 1. Identify sensors: Refer to the service manual to locate the inlet and outlet air thermistors (often near the air intake and exhaust ducts).
• 2. Inspect wiring: Check each sensor's wiring harness for chafing, pinched wires, or loose connectors. Reseat connectors at both the sensor and control board.
• 3. Test resistance: With the dryer unplugged, disconnect each thermistor and measure resistance at room temperature. Compare readings to Fisher & Paykel specifications. Sensors reading open or shorted must be replaced.
• 4. Replace faulty sensor: Install a new Fisher & Paykel-compatible thermistor in the same location and routing as the original.
• 5. Control board check: If sensors and wiring are good but E14 persists, the control board's sensor input circuit may be defective and require replacement.
• 6. Reassemble and test: Refit panels, restore power, and run a test cycle to confirm normal heating and that E14 is cleared.
