Outdoor temp reading is wrong.

  • Question
  • Updated 4 months ago
I have had an AcuRite model 75077 for 6 months. It has been working fine up until recently when the outdoor temperature suddenly started reading low by around 20 degrees. I have changed batteries in both the display and outdoor sensor units, changed to different channels and nothing has fixed the problem. The unit is positioned on my front porch in a shady spot protected from wind and rain. Any ideas?

Hello Jeff,

I understand you have done troubleshooting previously however, we need to ensure all steps have been exhausted.  Please verify you are using the battery recommendations and try the troubleshooting steps listed below.  If you have and the issue continues, the outdoor sensor will need to be replaced. We do offer a one year warranty on our products. Let us know if the issue continues. 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.
