Troubleshooting guide: My hearing aids won’t turn on

Hearing aids turn on in different ways. This is usually a simple process you probably don’t think twice about. Depending on the model, some turn on automatically when you take them out of their charging station. Others have an on-off button on the case.

But what happens if you pop in your hearing aids one day, and they don’t seem to turn on?

First, don’t panic, says Rebecca Younk, Au.D. She’s the chief audiologist at Associated Hearing Care with Beltone Technology near Minneapolis. It’s likely a small problem that’s easy to fix.

Here are the two main reasons why your hearing aids may not turn on — and how to troubleshoot.

Problem: Your hearing aids are dirty

The receiver of your hearing aid — the part that goes into your ear canal — is protected by a dome and wax guard. These parts can get clogged with earwax. “The number one reason why hearing aids won’t turn on is earwax,” Younk says.

• First, check your hearing aid app. Your hearing aids may be turned on but not producing sound. Open the app on your smartphone and see if the hearing aids are connected. “If they are, it means the dome or the wax guard needs to be cleaned or replaced,” Younk says.
   
• Next, check the dome (or ear mold). If that’s dirty, you should wipe off the wax or other debris with a soft cloth or small alcohol wipe.
   
• Finally, check the wax guard. This is the tiny mesh cap — also known as the wax filter or trap — that sits underneath the dome or ear mold. Change it if you see that it’s filled with wax.

Problem: Your hearing aids are not charged

If you look at the app and see that your devices aren’t connected, then it may be a battery issue, says Younk.

If your hearing aids use rechargeable batteries: It could be that your devices didn’t get charged properly overnight.¹

• First, make sure the charger is plugged in all the way and that you’re putting the hearing aids in the charger correctly.
• Try a new cord or outlet to see if that fixes the problem.
• Check if both charging ports are working. Try flip-flopping the hearing aids to see if one port charges but the other doesn’t.

If your hearing aids use disposable batteries: First, make sure the battery door is closed correctly. Sometimes that fixes the issue right away. If not, it may be time to put in a fresh battery. These tiny button-sized batteries usually need to be replaced every 3 to 7 days.²

What if you’ve tried the steps above and your devices still won’t turn on? Then get in touch with your hearing care professional. They may want to look at your devices in person to see if repairs or adjustments are needed.

Most likely, it’s a minor issue, and one you can fix at home before going on with your day.
