I changed the batteries, switched ABC with same results. Was mounted 5' above the roof and has been working good. Just stopped one day and froze numbers. Reset and removed the batteries, switched the ABC switched and units connected and went back to 40/1. Unit is just under a year old. Bought at Lowes.

Hello Chuck,

What is the name brand of the batteries you are using in the weather station? What is the model number of your outdoor sensor?  Our newer sensors do have a replacement piece that is available if you should see the -40 degree reading.  Once we have the model number of your sensor we will be able to determine if your sensor is compatible with the replacement piece.

Same here.  Model # 01602BPDIA2.  All functions except outside temp and humidity work.  I replaced all batteries with new Duracell alkalines.  I live in S. Florida so don't need lithiums.

Hello J Barrie and Bobert,
Please verify you are using the battery recommendations and try the troubleshooting steps listed below. If this does not correct the issue, please provide the model number listed on the bottom of the outdoor sensor.  When and where were your units purchased? Thank you.


•Verify you are using fresh alkaline batteries or lithium batteries (when temperature is below -4°F/-20°C) 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.

Hard reset:
- Bring both units side by side and remove all batteries, unplug display if it has an ac adapter
- Change the ABC Switch to a different setting and ensure that both are on the same setting. example - If on A, move both to C
- Place batteries into the outdoor sensor first
- Place batteries into display
- Allow units to sit side by side until they connect.
