Why Frigidaire dehumidifiers make noise?

As I mentioned, there are a few reasons your why Frigidaire dehumidifiers make noise. These reasons are as follows:

  • Blower Wheel
  • Fan Blade
  • Fan Motor
  • Compressor

1. Loose Blower Wheel:

The blower wheel in a dehumidifier draws air into the unit through the coils and then pushes it out as dry air. If the blower wheel is loose, it can cause a rattling or vibrating noise. This could be due to wear and tear over time or improper installation.

To solve this issue:

You will need to tighten the blower wheel with a screwdriver.

  • First, unplug your dehumidifier from the power source before attempting any repairs.
  • Then, locate the blower wheel in your dehumidifier. It is usually located near the coils and can be easily accessed by removing a panel or cover.
  • Use a screwdriver to tighten any loose screws on the blower wheel.
  • Once all screws are tightened, turn on your dehumidifier to see if the noise has stopped.

If the noise persists, you may need to replace the blower wheel altogether.

2. Loose Fan Blade:

After checking the blower wheel, the issue could be with the fan blade if you still hear a noise from your Frigidaire dehumidifier. The fan blade pushes air across the coils to remove moisture. If it is loose or damaged, it can cause scraping or squeaking noises. The fan blade can become loose due to wear and tear or improper installation.

To solve this issue:

  • Make sure to unplug your dehumidifier before attempting any repairs.
  • Locate the fan blade, which is usually located near the back of the unit.
  • Gently push on the blades to see if they are loose or wobbly. If so, you will need to tighten them with a screwdriver.
  • If the blades appear damaged, you may need to replace them altogether.

3. Faulty Fan Motor:

If you have checked the blower wheel and fan blade and still hear a noise from your Frigidaire dehumidifier, the issue could be with the fan motor. The fan motor rotates the fan blade to push air through the unit. It can cause a grinding or humming noise if it is damaged or worn out.

Possible reasons for fan motor damage:

  • Overuse of the dehumidifier
  • Lack of maintenance and cleaning
  • Power surges

To solve this issue:

  • Unplug your dehumidifier before attempting any repairs.
  • Locate the fan motor, which can usually be found near the back of the unit.
  • Check if any obstructions or debris are blocking the fan motor, which could be causing it to make noise.
  • If the fan motor is damaged or malfunctioning, you may need to replace it with a new one.

4. Faulty Compressor:

Finally, if your Frigidaire dehumidifier is making a loud noise that sounds like grinding or banging, the issue could be with the compressor. The compressor is responsible for compressing and circulating the refrigerant through the unit to remove moisture from the air. It can become faulty due to wear and tear over time or electrical issues.

To solve this issue:

  • Make sure to unplug your dehumidifier before attempting any repairs.
  • Locate the compressor, which is usually at the back of the unit.
  • Check for any loose or damaged parts and tighten or replace them accordingly.
  • If the issue persists, it may be a sign of a faulty compressor, and you will need to have it replaced by a professional.

Prevent Tips Your Frigidaire Dehumidifier From Making Noise?
