Here are some steps you can take to try and fix the noisy fan:
Clean the Fan: Dust and debris can accumulate on the fan blades, causing it to make noise. Unplug the fridge and access the fan (usually located at the back of the fridge or behind a panel). Gently clean the fan blades using a soft brush or compressed air.
Check for Obstructions: Sometimes, items or debris can get lodged near the fan, causing it to make noise. Make sure there are no obstructions near the fan area, and remove anything that might be interfering with the fan's rotation.
Level the Fridge: If the fridge is not level, it may cause the fan to make noise. Ensure that the fridge is placed on a level surface to avoid any vibrations that can lead to noise.
Inspect the Fan Motor: The fan motor itself could be causing the noise. If it's damaged or faulty, it may need to be replaced. If you're not comfortable doing this yourself, consider contacting a professional repair service to handle it for you.
Check for Loose Parts: Vibrations from loose components can also contribute to noise. Inspect the fridge for any loose screws, panels, or other parts, and tighten them if necessary.
Proper Ventilation: Ensure that the fridge has enough space around it for proper ventilation. Overheating due to inadequate ventilation can put additional strain on the fan motor and cause noise.
Contact Manufacturer or Seller: If the issue persists and the fridge is still under warranty, consider reaching out to the manufacturer for assistance. If you bought it from a seller, they might be able to offer guidance or a replacement if it's a known issue.
Remember always to unplug the fridge before attempting any maintenance or repairs to avoid any potential electric shock hazards.
If you're unsure about performing any of these steps yourself, it's best to consult a professional appliance repair technician. They can diagnose the issue accurately and recommend the appropriate course of action to resolve the noisy fan problem.
