5-in-1 Temperature Reading Too High

Follow

The sensor’s aspirating fan helps internal airflow to ensure accurate ambient temperature readings while the sun is shining on the sensor. If the outdoor temperature readings are reporting too high, especially on hot or sunny days, verify the internal aspirating fan is running by opening the 5-in-1 sensor and visually inspecting the fan. If the fan is blocked by debris, most obstructions can be cleared with a gentle puff of air.

When the fan is spinning, you will hear a humming noise. The following troubleshooting steps can be used if the fan is loud when you are at least 10ft away from the sensor. 


To open the 5-in-1 sensor, you will need:

Philips-head screwdriver

5-in-1 Outdoor Sensor 

 

  1. Remove the four outer screws on the bottom of the sensor. Keep the screws for re-assembly. Note: Be careful not to remove or adjust the rain calibration screws located beneath the rain gauge.
  2. Separate the upper and lower halves of the sensor.
  3. Check the fan for debris, such as insects or spider webs. A gentle puff of air can clear most obstructions safely.                                                                                                      
  4. If no debris appears to be blocking the fan, position the top white portion of the sensor (that has the solar panel) in direct, bright sunlight. The fan should power on immediately without any assistance (such as a nudge). Note: Artificial light, such as flashlights, cannot be used as a substitute for actual sunlight. Also, overcast days may not be sunny enough to power on the fan.
  5. To reassemble the sensor, bring the two halves of the sensor back together.
  6. Reinstall the four outer screws to join the upper and lower portions of the sensor together.

 

If the fan does not spin on its own in direct sunlight with no clouds, a replacement wind cup assembly is suggested. Click Here to Review the Pro+ Upgrade for the 5-in-1 Sensor
