Hello Robert,
If the battery recommendations and troubleshooting steps below do not correct the issue, the outdoor sensor will need to be replaced.  For your convenience there is a link below to the replacement sensor needed.  Please let us know if you have any questions. Thank you.

Batteries:

•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.

Thanks for the reply after further investigation, I found that when I changed my sensor batteries, the until begin picking up the neighbor's sensor. Their's does not have humidity, so although the temp looked right, there is no humidity. I switched to channel B and all is normal.
