Dehumidifier shuts off and will not restart until it cools down.

Safety first: Unplug the dehumidifier before cleaning or inspecting internal parts.

• Step 1 – Clean air filter: Remove and wash the air filter with mild soap and water. Let it dry completely before reinstalling.
• Step 2 – Clean coils: Vacuum dust from both evaporator and condenser coils. Use a soft brush to avoid bending fins.
• Step 3 – Verify fan operation: With the cover on, run the unit and ensure the fan starts immediately and runs at full speed. If it is slow or intermittent, replace the fan motor.
• Step 4 – Improve ventilation: Move the unit away from walls and heat sources. Ensure at least 12 inches of clearance around grilles.
• Step 5 – Monitor operation: If the unit still overheats and shuts down, the compressor may be failing and drawing too much current, requiring professional diagnosis.

Overheating protection is a safety feature; do not bypass it. Address the root cause instead.
