Dehumidifier is very noisy during operation (rattling, buzzing, or grinding)

Safety: Unplug the unit before tightening or adjusting components.

Steps to reduce noise:

• Level the unit: Place the dehumidifier on a solid, level surface. Adjust feet if provided.
• Check for loose panels: Tighten all exterior screws. Add thin foam tape between rattling panels if needed.
• Inspect fan and blower: Remove the grille and check that the fan blade or blower wheel is tight on the motor shaft. Tighten set screws or clips. Remove any debris rubbing against the fan.
• Listen to motor bearings: If the noise is a grinding or squealing from the fan area, the motor bearings may be worn. Replace the fan motor.
• Compressor mounts: Inspect rubber grommets under the compressor. Replace any that are cracked or missing to reduce vibration transfer.

Test: Run the unit after adjustments. Noise should be significantly reduced and limited to a smooth fan and compressor hum.
