Dryer displays E19, may not start or may shut down quickly, often on models with humidity control

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

• 1. Check installation environment: Ensure the dryer is not installed in a very damp or corrosive environment (e.g., unventilated bathroom). Improve ventilation if necessary.
• 2. Locate humidity sensor: On some Fisher & Paykel models, the ambient sensor is near the air intake or behind the control panel. Refer to the service manual.
• 3. Inspect and clean: Check the sensor for dust buildup or contamination. Gently clean with a dry, soft brush.
• 4. Inspect wiring: Verify the sensor harness is intact and securely connected to the main control.
• 5. Replace sensor: If the sensor is damaged or tests out of specification, replace it with a compatible Fisher & Paykel ambient sensor.
• 6. Control board: If E19 persists with a known-good sensor and wiring, the main control may require replacement.
