Part: User selection/settings

Moisture sensor contamination or failure

How to Identify: Sensor not correctly detecting dryness; moisture levels inaccurate, cycle may stop prematurely; sensor may appear coated or dirty.

Part: Moisture sensor

Internal airflow blockages including condenser or vent pipe obstruction

How to Identify: Vent or condenser unit blocked causing poor airflow; warm air not expelled efficiently; condensation issues in condenser models.

Part: Vent hose / condenser unit

Faulty heating or thermostat elements
