Dehumidifier shuts off after a short time and restarts frequently

Safety first: If the unit feels excessively hot or emits a burning smell, unplug immediately.

• Step 1 – Clean filter and grilles: Wash the air filter and vacuum dust from intake and exhaust grilles to improve airflow.
• Step 2 – Check room temperature: Ensure the room is within the operating range. Very high temperatures can cause the compressor to overheat and shut off.
• Step 3 – Observe cycle: Time how long the compressor runs before shutting off. If it runs only a minute or two, the overload protector may be tripping.
• Step 4 – Inspect condenser coil (advanced): Remove the cover and clean the warm condenser coil. Blocked fins cause overheating.
• Step 5 – Evaluate overload and compressor: A failing compressor or overload protector can cause repeated short cycling and should be tested and replaced by a technician.

When to call a technician: Persistent short cycling after cleaning suggests a compressor or electrical issue that requires professional diagnosis.
