Why Is My Hearing Aid Not Working? Common Problems and When to Get It Repaired

The most common reasons a hearing aid stops working include dead batteries or low charge, earwax clogging the sound port or wax filter, moisture damage, and microphone or speaker failure.

When a Hearing Aid Stops Working, Start With the Basics

Hearing aids are sophisticated electronic devices worn in or near the ear every day. They are exposed to earwax, moisture, sweat, and physical handling that eventually take a toll on even the most durable devices. When a hearing aid suddenly stops working or sounds different than normal, the cause is often something simple that can be addressed at home. Knowing where to start saves time and a trip to the clinic for problems you can solve yourself.

But some issues go beyond home maintenance and require professional hearing aid repair. Knowing when to bring the device in is equally important. This guide walks through the most common problems and how to approach each one.

Problem 1: No Sound at All

When a hearing aid produces no sound, the most common cause is the battery. For disposable battery devices, the battery may be dead, installed incorrectly, or have its protective tab still in place. Replace the battery with a fresh one and make sure the battery door clicks shut completely.

For rechargeable hearing aids, confirm that the device was properly seated in the charger and that the charger is plugged in. If the charging indicator did not activate, try a different power outlet.

If power is confirmed and the device still produces no sound, check whether the volume control has been accidentally set to minimum, or whether the device has been switched to a program that mutes external sound. If none of these resolve the issue, bring the device in for professional assessment.

Problem 2: Muffled or Distorted Sound

Muffled sound is the most common hearing aid complaint and the most commonly fixable at home. The sound port, the small opening at the tip of the hearing aid through which sound exits, can become clogged with earwax. Most hearing aids include a wax filter or wax guard that prevents earwax from entering the device. When this filter becomes saturated, sound becomes muffled.

Cleaning the sound port with the brush or cleaning tool provided with your device and replacing the wax filter usually resolves muffled sound. If you are unsure how to replace the wax filter, or if cleaning does not help, the team at American Family Hearing Aid Center can perform this during a service appointment. Patients whose ears produce significant earwax should also consider regular ear cleaning to reduce the amount of wax entering the device.

Problem 3: Whistling or Feedback

Acoustic feedback, the high-pitched whistling sound that hearing aids sometimes produce, is caused by amplified sound leaking out of the ear canal and being picked up by the microphone again. This can happen when the device does not fit properly in the ear, when the dome or earmold has become loose or damaged, or when the ear canal is partially blocked by earwax.

Try repositioning the device and checking that the dome or earmold is properly seated. If the fit has changed because the ear canal shape has shifted over time, a refitting may be needed. Earwax buildup in the canal can also cause feedback by partially blocking the sound path and directing it back toward the microphone.

Problem 4: Intermittent Sound

A hearing aid that cuts in and out is often dealing with a corroded battery contact, moisture in the device, or a loose component. Clean the battery contacts gently with a dry cotton swab if they appear discolored. Allow the device to sit in a hearing aid dehumidifier overnight, as moisture is a frequent culprit in intermittent performance.

If the problem persists, the issue is likely internal and requires professional repair.

Problem 5: Physical Damage

Dropped hearing aids, devices exposed to submersion in water, or instruments with visible cracks or bent components should be brought in for professional assessment. Physical damage can sometimes be addressed through in-house repair, while more significant damage may require sending the device to the manufacturer. The team at American Family Hearing Aid Center services multiple makes and models and will advise on the most appropriate course of action.

When Home Troubleshooting Is Not Enough

If you have worked through the troubleshooting steps above and the device is still not performing correctly, the next step is a professional evaluation. American Family Hearing Aid Center in Marietta offers repair services for a wide range of hearing aid brands and styles. Many repairs can be completed in-house; others may be sent to the manufacturer.

Patients should also be aware that regular professional maintenance, at least once or twice a year, prevents many common problems before they develop. A professional cleaning removes debris from areas that are difficult to reach at home, and a performance check ensures the device is operating at its intended specifications. Contact the clinic to schedule a repair or maintenance appointment.
