My 5 in 1 sensor registers high daytime temps. When compared to other Weather Underground stations in my area, my temps (KCOBEULA14) are 15 deg higher.

John it sounds like you need to check and see if the fan in your 5 in 1 sensor is running. If can get close to it you should be able to hear it running. If not you will need to take it apart and see if something is stopping it from turning. When you have it apart the fan should start running by itself when the solar panels are facing the sun, if not then its time to replace the fan.

I've already taken the station apart to check that.  Fan runs immediately when sun hits the "two" solar panels.  The station is only about 5 months old so there was no dirt or debris anywhere.
I'm at a loss as to why temp readings are so high.  At night my temps corresponds with the other readings in my area.
FYI...it's mounted on a 7 ft 4x4 over meadow grass.

The air sensor could be bad. If you have a newer 5n1 those are eazily replaced.

I do not think these sensors have been available at Acurite for a very long time. When will they be back in stock?

And if you live in Canada, the shipping cost of a replacement sensor board is ridiculous. It fits in an envelope, but you pay like it was an orange crate.

John I just looked at your weather underground page and saw some difference in temps. The stations to your west are 2000 to almost 3000 feet higher than yours, the stations that are at your same elevation are about the same temp as yours and the higher temps are lower than yours I think that may be what you are seeing.

Hello John,

Please verify you are using the battery recommendations and try the troubleshooting steps listed below.  After this is done, what does your indoor and outdoor reading compare? Thank you.

Batteries:

•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, unplug display if it has an ac adapter
- Change the ABC Switch to a different setting and ensure that both are on the same setting. example - If on A, move both to C
- Place batteries into the outdoor sensor first
- Place batteries into display
- Allow units to sit side by side until they connect.
