Possible Causes

Humidity sensor reading out of range (saturated), Sensor exposed to liquid water, Failed humidity sensor module

How to Fix / Troubleshooting

Safety: Unplug the Camry humidifier before opening the control panel.

Steps:

  • 1. Dry the sensor: If the unit was exposed to steam or splashes, allow it to dry in a warm, dry room for several hours unplugged.
  • 2. Inspect sensor location: Ensure the humidity sensor is not directly in the path of mist output. Relocate slightly if possible, following Camry guidelines.
  • 3. Clean sensor vents: Gently clean dust from the sensor housing with a soft brush.
  • 4. Replace sensor: If H1 persists, replace the Camry humidity sensor module as described in the E3 procedure.

Note: Avoid placing the humidifier directly under shelves or surfaces where condensation can drip onto the sensor.
