There have been lot's of post with people having the same problem.  Most likely bad part.  Make sure you register it so you can get a replacement.

Hello Leila,

What is the name brand of the batteries you are using in the thermometer? Where was it purchased at? We understand that you have done troubleshooting steps but please make sure they are done in the specific order listed below:



  1. Bring both the sensor and display unit indoors and position them side by side.
  2. Remove all batteries from the sensor.
  3. Remove all power from the display unit.
  4. Wait 2 minutes to ensure that any remaining battery power has discharged from both units
  5. Reinstall batteries in outdoor sensor first, the red light on the sensor should flash once quickly.
  6. Watch for the light on the sensor to flash a second time, it should flash approximately every 30 seconds.
  7. Power up the display last.
  8. Let units sit within a couple feet of each other for 5 minutes to ensure a wireless signal is received.
    *The display should receive the signal within several minutes. 
  9. After a connection has been established you may place the sensor outdoors. 
    *If the signal connection fails after the units are separated try a new location for the display unit, the sensor or both. 
Make sure you are following the battery guidelines below:



  • Verify you are using fresh alkaline batteries or lithium batteries (when temperature is below -4oF/-20oC) in sensor.
  • Quality brand batteries are recommended, including Duracell, Rayovac, Energizer, or Kirkland.
  • Verify batteries are fresh. The battery expiration date should be at least 6 years out. Batteries can lose 3% power or more every year in storage.
  • Heavy duty, extra strength or generic / store brand batteries are not recommended for use with AcuRite products because they may cause performance irregularities due to the way these types of batteries disperse power. Each battery should not exceed 1.6 volts.
  • Rechargeable batteries are not recommended for use with AcuRite products because they may cause performance irregularities due to the voltage instability of these types of batteries.
  • Mixing different battery types (brands, old/new, etc.) is not recommended.

We are using Duracell alkali batteries. We got it as a gift so it can't be returned. We have done all the trouble shooting a number of times. We are very disappointed in this product. We would like a new one sent to us.

Hello Dwight,
If you are experiencing this issue after the troubleshooting steps have been exhausted, we would recommend replacing the outdoor sensor. Do you have model 00606tx? What is the model of your unit?  When and where was this purchased? Thank you.
