I walked by my acurite 1536 this morning and noticed it was making a soft grinding sound.  I had never heard that before.  I took it down and changed the batteries, but it made the same sound after putting it back on it's mount.  Any ideas?

Robert I'm guessing your talking about a 5 in 1 sensor. The noise is either  coming from the aspirating fan going bad or hitting something inside or the anemometer bearings  needing lubrication. It is normal for the fan to make some noise but if you never heard it before its likely something changed.

Hello Robert,

 We see that you have posted in other threads on the forum regarding the fan. When was your model purchased? Please check for debris by following the instructions below. Thank you.

Items Needed: 5-in-1 sensor, Philips screwdriver, toothbrush (optional), moth ball (optional)

  1. First, open your 5-in-1 sensor by removing the (4) four screws from the bottom. The screws toward the center of the sensor are for Rain Gauge calibration only. Do not adjust these screws.
  2. After your sensor has been opened, remove any insects, cobwebs, or debris. An old toothbrush can help to clean out the hard-to-reach places.
  3. To further defend against insects crawling into your sensor, you may place a moth ball in the nook, near the tipping buckets (shown in video). Adhere the moth ball to the sensor with a piece of tape.
    • Note: Insect repellant may be used for additional protection, but should not be sprayed on the internal components or into the sensor.
  4. Reassemble the 5-in-1 sensor by replacing the (4) four screws on the bottom of the sensor that were removed earlier.
