We received the acurite 02048-rx for Christmas. Followed the setup and installation as describe and tada weather on the wall. Last week the unit flaked out and the readings went crazy. 158 to -12. (comfy 60 outside). Read all the trouble shooting steps and post I could find. Reset the unit re-positioned the unit and still not registering. The light on the sensor is flashing and I have noticed that with each flash the outside readings change. I am really concerned as I see that this is a common issue with these units. Will I have to replace the sensor every month? Any suggestions or help is greatly appreciated. And yes I am using energizer batteries and they are new.
