Hello Howard,

Please follow the troubleshooting steps listed below.  If this does not correct the issue please contact AcuRite Customer Support at 877-221-1252 for a possible warranty claim.  Thank you and have a great day!

Batteries:
•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.

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.

They did connect, but outdoor Humidity is still 99%. Can I replace the Humidity sensor if you send it to me?

Assuming it is a unit with the SHT21 sensor chip, you can solder in the newer temp/humidity replacement module.  It involves cutting off the connector and soldering the 4 wires in the proper places on the main board.

Obviously this is something that would void your warranty if it is still valid.

If you have one of the newest 5n1s, you can install the replacement module without any soldering... it has a socket that plugs into the main board.  It does not void your warranty.

I don't believe I have a warranty on it, it's 3 years old. I have no problem with soldering a new sensor on the main card. How do I go about getting a the replacement sensor. My only alternative is to buy a new outdoor unit, since the inside unit should be compatible with it.

I would assume that this sensor is the same for my vn1txca1, just the connection is different. Wire color code is the same?

Hello Howard,

The new temperature and humidity board is not compatible with the old sensors.  We would recommend purchasing a new outdoor sensor.  The new sensors do have the replaceable board.  I have added links below that will bring you to the new sensors. Please let us know if you have any questions. Thank you and have a great day!

It's not color-coded, but the signals are labeled on each end.

Hi George,

I sent you this same question on another another conversation because I saw you just replied.

I have a 5 in 1 sensor from feb 2015 that the humidity board does not work, Can I purchase the new humidity board that is a plug in one on new models, cut the plug off it and take out the old board leaving its wires to the main board in tact and connect it up? I am not to handy on soldering

In theory it will work, but I'd recommend soldering for a good connection.  If you just twist the wires together it might be error-prone.

Also, if your 5n1 is using ribbon cable, they can be quite fragile and break off easily at the solder point, anyway.
