Brand New 5-in-1 reading higher than actual temps

I know there's several thousand posts on this topic, and by the time I sifted through them my warranty would be expired. :)

My brand new 5-in-1 reads temps about 5-7 degrees higher than actual, then drops to normal after 10-15 minutes, then this cycle repeats for a few hours while the direct sun hits the unit. This issue does not happen on overcast/rainy days, or at night. During those times, the temp is extremely accurate.

I climbed up to check the unit to make sure the internal fan is running, and although I didn't open the unit, I could hear the fan motor when I held my ear up next to it.

From what I've read in this forum, this issue happens when the internal fan is not running properly. Mine sounds like it is, so I'm asking what to do here.

Thank you.

Seems like the fan is not running at a steady rate. (ramping up and down) This could be a sign of a bad unit, either from the motor or bad feeds from the solar arrays.

Do you have 1 or 2 solar panels on your 5 in 1?  
Is the unit ever shaded (tall trees/buildings)?  You may need the Pro kit (2 panel) to provide more consistant fan power.

It's brand new and has the 2 solar panels. No shade either. In fact, I moved it from its original install location to make sure there would be no shade. Like I was saying, I can hear the internal fan running, so I'm just wondering if it's just not strong enough a motor.

I have a new 5 in 1 and am having the same issue. I have not taken it down yet to check that the aspiration fan is working properly, but hop to do that this week. My suspicion is that the aspiration fan doesn't adequately compensate for the direct sunlight.

Don't dismiss the possibility there is nothing wrong either... Temperatures should be taken in a sunshine filled location, with a shield to protect the sensor from the sun hitting it directly. The temperature will be too low if the sensor is in a tree or likely will be incorrect if it is against a building, or even near a building.

Hello Everyone,

It is possible that there is debris inside of the sensor that is affecting the full capability of the aspirating fan. To check for debris please follow the steps provided.

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.
  5. Clear out any false readings that were taken while you were cleaning your sensor by pressing the CLEAR TODAY button on your 5-in-1 compatible display.



To ensure that your professional weather center performs at its best, follow these guidelines to choose a mounting location for the wireless sensor:

Install Away from Heat & Humidity Sources

  • DO NOT place the wireless sensor near localized heat sources like heaters, air conditioners, chimneys and exhaust vents. Install the wireless sensor away from asphalt or concrete as these surfaces radiate heat from the sun.
  • Also avoid installing the sensor near pools, spas, or other bodies of water as these water sources may affect the accuracy of the humidity.
Install Away from Sprinkler Heads

  • DO NOT install the wireless sensor where it will be directly sprayed by a sprinkler system. This will affect the rainfall measurement accuracy and may force water into the housing.
Wind & Rain Obstructions

  • DO NOT mount the sensor with obstructions above it, as this will affect proper rainfall measurement.
  • Also consider a mounting location that has very little structures around the sensor, to ensure proper wind speed and direction measurements.
Installation Height

  • DO mount the wireless sensor at least 5 feet off the ground (higher is better for accurate wind measurements) in an open area NO FURTHER than 300 feet (100 meters) from the display console. A typical installation would involve mounting the bracket to a secured length of 4"x4" wood (not included).
Level Installation

  • DO install the wireless sensor as level as possible to ensure accurate rain and wind measurements.
  • Use the bubble level on the top to ensure a level installation.
Solar Cell Orientation

  • DO install sensor onto the mounting bracket with the solar cell facing SOUTH.
  • This is important to ensure that the cell receives as much sun as possible, and also orients the wind direction properly.



Thank you.
