If your AcuRite Atlas® (7-in-1) sensor is losing connection to the display unit and/or AcuRite Access®, the low battery icon is often present on the display, or the sensor is going through batteries too quickly, please review the troubleshooting suggestions below. We expect recommended batteries to last between 12-24 months. If your batteries are not lasting at least one year, we would recommend the following troubleshooting steps.

You would want to ensure the following first:

• Verify you are using fresh batteries in the sensor. Lithium batteries are recommended for installation locations where temperatures can go below -4°F/-20°C.
• Verify you are using batteries with a nominal voltage of 1.5 volts.          
  NOTE: Some rechargeable batteries carry low or inconsistent voltages that may not properly power the device.  
• Mixing different battery types (brands, old/new, etc.) is not recommended.

• When fresh batteries are installed, make sure the light in the battery compartment of the Atlas sensor flashes every 10 seconds. If you notice 5 quick flashes when fresh batteries are installed, there may be a loose connection within your Atlas sensor.

Check all connections:

Before installing fresh batteries, please check all connections inside the AcuRite Atlas® (7-in-1) sensor.
NOTE: Silicone grease can be added directly to all of the connectors to ensure a more secure connection.

• Wind Assembly Connectors:
  1. Please remove the wind assembly as shown below.
  2. Unplug the connectors, as shown below, for 1-2 minutes.
     
  3. Reconnect the connectors. When re-connecting the assembly plug, you should feel/hear a snap when the connection is 100%.
  4. Reinstall the wind assembly.
     
     
     
• Rain Bucket Connectors
  1. Open your AcuRite Atlas® (7-in-1) sensor by detaching the rain bucket (black portion) from the bottom half of the sensor, as shown below.
  2. Unplug the connectors between the rain bucket and base of the sensor for 1-2 minutes.
  3. Reconnect the connectors. When re-connecting the plug, you should feel/hear a snap when the connection is 100%.
  4. Reassemble the AcuRite Atlas® (7-in-1) sensor by reattaching the rain bucket to the bottom half of the sensor.
     
     
     
• Temperature and Humidity Sensor
  1. On the bottom of the AcuRite Atlas® (7-in-1) sensor, there is a vent cover that is held in place by 2 tabs. Remove the vent.
  2. Under the vent, there is a cylinder that is clipped in with 2 tabs. This is the temperature and humidity sensor. Remove the temperature and humidity sensor to expose the fan.
  3. Unplug the white cable connectors attaching the temperature and humidity sensor to the Atlas sensor for 1-2 minutes. 
  4. Inspect the temperature and humidity sensor board and connections for any signs of corrosion. If the temperature and humidity sensor board is corroded, an AcuRite Atlas® Temperature and Humidity Sensor Replacement model #06097M is recommended.
  5. Reconnect the temperature and humidity sensor's connectors. When re-connecting the sensor assembly plug, you should feel/hear a snap when the connection is 100%.
  6. Install the temperature and humidity board over the fan assembly, confirm the tabs do not block the fan from spinning.
