Smart Ear: How to fix a thermometer that won't power on

If your Smart Ear thermometer won't turn on, don't worry these steps will help you.

If your thermometer has a side button, and you've already tried fresh batteries:

  1. Remove the batteries.
  2. Clean the battery cavity with a cotton swab
  3. Put the batteries back in.

If your thermometer does not have a side button, and you've already tried fresh batteries:

A failed firmware update could be causing the problem. This is especially likely if you just got your new thermometer, connected it with the Kinsa app, and it worked for the first time but then wouldn't turn on again for the second time.

In that case, you can fix it right away by using the Kinsa app's Thermometer Recovery feature: 

  1. Open your Kinsa app
  2. Tap the ⚙️Settings gear in the top right corner
  3. Tap Thermometer Recovery
  4. Follow the on-screen instructions

If your thermometer still won't power on after following these steps, please tell our Customer Happiness team that you've followed this "Smart Ear won't power on" guide and we'll take care of it!
