Just received a brand new 6004m sensor to replace an 18 month old 1010w sensor with humidity stuck at 99%. After 5 hours, the brand new unit purchased  directly from Acurite is doing the same thing; humidity stuck at 99%. Followed the reset steps, and no change. Very disappointed. Perhaps Acurite can send me a new sensor on their dime...I specifically bought a new sensor because of the replaceable temp/humidity sensor, but I feel I shouldn't have to pay for a replacement after less that 12 hours of ownership.

Hello Ken,

Please try the following troubleshooting steps.  If this does not correct the issue, we are happy to assist you with your one year warranty.  Thank you.



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.
