Hello Dreama,

What is the model number of your weather station? Where was it purchased, and how long have you had it? What is the brand of batteries you are using in the weather station? If you have a sensor that has an A-B-C switch on it please attempt the troubleshooting steps below:



You want the display and sensor to be at least 3 feet from electronics such as televisions, microwaves, computers & radios. Follow 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.

Perform a hard reset:


1.Bring both the sensor and display unit indoors side by side.

2.Remove batteries from the sensor.

3.Remove batteries from the display unit and unplug the AC adapter (if applicable).

4.Wait 2 minutes to ensure any remaining battery power is discharged from both units.

5.Change the A-B-C Channel on both the display and sensor making sure they both match.

6.Reinstall batteries in outdoor sensor first.

7.Reinstall batteries in display unit second.

8.Let the units sit within a couple feet of each other for 30 minutes when comparing for accuracy
* 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 or different location for the display unit, the sensor or both.




If you have a sensor that does not have an A-B-C switch then please try the steps below:

You want the display and sensor to be at least 3 feet from electronics such as televisions, microwaves, computers & radios. Follow 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.

•Mixing different battery types (brands, old/new, etc.) is not recommended.

Perform a hard reset:
1.Bring both the sensor and display unit indoors and remove batteries from each.
2. Leave the batteries out for at least 2 minutes.
3. After the 2 minutes put the batteries in the outdoor sensor only. Look for the red light on the sensor to flash.
4. Reinstall batteries in the display.
5. Give it a couple of minutes and the outdoor temperature should display.
Once the temperature displays you can put the sensor back outside.
