Hearing Aid Repairs

Today we are going to focus on how to repair hearing aids.  If you have a receiver-in-the-canal (RIC) hearing aid that sounds weak or is completely dead, there are a few things you can try at home.

Hearing Aid Components We Will Focus On:

  • Domes – Covers the wax guard
  • Batteries – gives the hearing aid power.
  • Wax Guard – Prevents ear wax from getting into the hearing aid.

Step 1:  Changing the Battery

First we want to change the battery.  You will want to take the old battery out and grab a new one.  Hearing aid batteries have a tab on the back of them and are zinc aired batteries.  This means they are activated by the air.  Do not remove the battery off the tab until you are ready to use them.  Once the tab is removed, install the new battery.  Give it time to start up.

If a new battery does not fix the problem, let’s move on to step two.

Step 2:  Removal of Dome & Wax Guard Change

  • Remove the dome on the bottom of the hearing aid.  The best way to do this is to put your fingernail under the dome and roll it off.
  • After the dome is removed, you will see a white filter or wax guard which you will want to change.  The wax guard is designed to stop ear wax from getting into the hearing aid.
  • New wax guards will come on a plastic stick or something similar with a new wax guard on one end and empty on the other.
  • To remove the old wax guard, snap the empty end of the stick onto the wax guard and pull off.
  • To install the new wax guard, simply snap the new one on to the hearing aid.
  • After the new wax guard has been installed, you will want to put the dome back on.  On the dome there is a hole the fits directly over the hearing aid.
