00611A3 outdoor sensor locks during rain

  • Question
  • Updated 3 months ago
Purchased two 00611A3's from 3rd party at Amazon. Both have failed within the first two weeks.

Set up two units indoors and one outdoor. During rain, outdoor sensor read 99% humidity and indoor screen froze and would not update.

I disabled that sensor and put new batteries in the second outdoor sensor. A week later, during rain, this sensor also failed, with the indoor displays reading humidity at 99% and frozen there. 

Neither of the outdoor sensors would work - I tried changing batteries indoor and outdoors to no avail, indeed could not even get the outdoor sensor to register on the screen - either one.

After taking all batteries out of all devices and leaving them out for 12 hours, I have been able to reset one of the outdoor sensors and it is working.

But, to have to go through this each time it rains is disappointing.

AcuRite has only been accurate until the sensor stops working.

So disappointed.

Hello Murray,
Using two of these models in the same location can cause interference between the two sensors. Where do you have the sensors mounted? Did the sensor get wet during the rain? Please verify you are using the battery recommendations and try the troubleshooting steps listed below. 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

- Place batteries into the outdoor sensor first

- Place batteries into display

- Allow units to sit side by side until they connect.

Thank you for your response.

Yes, I understand that you should not use the two sensors in close proximity.

I was using the two indoor displays but only one outdoor sensor.

When the first outdoor sensor failed and the indoor displays locked, I took that outdoor sensor out of service and replaced it with the second one, which subsequently failed in the rain as well.

Since I have been able to finally reset everything, the unit has been working properly for several days, even through rain.

As to your question ...

yes, the unit got wet.  But I thought the outdoor sensor would be water-proof or at least water-resistant.

as your website indicates ...

  • Durable, all-weather construction – perfect for indoor or outdoor use

Since the units have begun working again, it has rained, although the high humidity recorded is only 78%.  So it has not gone to 99% and the displays have not frozen.  Whether in the rain the humidity should read as high as 99%, I would think so, but again it has not exceeded 78% in the past rainstorm.

thanks again for trying to help

Hello Murray,

The sensor is water resistant but you want to keep it protected from the direct weather elements such as rain and sun.  If it does get too wet it could cause the sensor to short out or stop working.  We are glad that you were able to get it corrected. Please let us know if there is anything we can assist you with.
