Dehumidifier is very noisy or rattles during operation

Safety: Unplug before tightening or adjusting internal parts.

Steps:

• Check placement: Ensure the unit is on a solid, level surface. Avoid hollow or uneven floors that amplify vibration.
• Inspect fan blade: Remove the front or top cover and check that the fan blade is firmly attached to the motor shaft. Tighten any set screws or push the blade fully onto the shaft.
• Look for loose parts: Tighten any loose screws on the cabinet, handle, or grille.
• Compressor mounts: Access the compressor area and verify that rubber mounts and bolts are intact and snug, but not overtightened.
• Fan motor bearings: If the noise is a grinding or squealing from the fan area, the fan motor may need replacement.
