Devola dehumidifier shows incorrect room humidity (e.g., always 30% or 80%) and cycles improperly.

Safety: Unplug before opening the housing.

• Verify with external hygrometer: Compare the dehumidifier reading with a separate, known-good hygrometer.
• Clean sensor area: Locate the humidity sensor near the air inlet and gently clean dust from around it.
• Relocate unit: Ensure the unit is not placed where warm discharge air recirculates directly into the inlet, which can skew readings.
• Replace sensor: If readings remain far off, replace the humidity sensor module with the correct Devola part.
