To repair a hearing aid, find out the cause of the problem, and use common solutions such as replacing the battery, according to Oticon. If no solutions fix the problem, a hearing care professional can repair or replace the device.
Build up of ear wax is the biggest reason why hearing aids need repair, notes Healthy Hearing. The natural excretion of ear wax can clog the hearing aid and potentially require a professional cleaning. Dust, debris and dropping the hearing aid are also causes for repair.
Clean ear wax off the hearing aid with a small brush and/or soft cloth, suggest Starkey Hearing Technologies. Hearing aids have a life expectancy of five to seven years, and if the damage is visible or the hearing aid has been stepped on, it most likely will require replacement. However, some hearing aids cannot be repaired. The best way to avoid professional repair or replacement is to keep your hearing aid clean and ensuring it has no contact with water.
If the hearing device has no sound, the battery may be worn out, the sound outlet may be clogged, or the microphone opening may be clogged, notes Oticon. Clean the sound outlet, or change the wax filter if it is clogged. If the microphone opening is clogged, clean it with a brush. If none of the solutions work, replace the battery.
If a whistling or howling sound is heard when the device is inserted, there is a problem with earwax, or the hearing device is inserted improperly, explains Oticon. First remove and reinsert the hearing aid following the proper instructions. If the whistling or howling sound is still there, go to a doctor to look at problems with the ear canal, such as excess earwax.
If a distorted sound is heard, the problem may be due to the battery contacts, the battery itself or hearing aid settings, according to Oticon. To fix problems with the battery contacts, which may be dirty or corroded, open and close the battery compartment several times. To fix problems with the battery, clean battery surfaces with a dry cloth, or replace the battery if cleaning it doesn't fix the problem. Finally, make sure that the hearing aid is switched to the microphone signal and not telecoil.
