Choosing the right indoor outdoor thermometer is important for monitoring temperatures in your home and outdoor spaces. The Acurite brand offers affordable and reliable thermometers that are popular choices. However, like any electronic device, Acurite thermometers may occasionally need to be reset to function properly. Resetting can help if your Acurite thermometer displays inaccurate readings, doesn’t update, or has other issues.
Resetting an Acurite indoor outdoor thermometer is usually a straightforward process that can be done in just a few minutes. Here is a comprehensive guide on how to successfully reset your Acurite thermometer to restore accurate temperature tracking for your home.
Steps to Reset an Acurite Indoor Outdoor Thermometer
Resetting an Acurite indoor outdoor thermometer is a simple procedure that involves locating the reset button and pressing it with a pointed tool. Follow these steps:
Locate the Reset Button
The small reset button is located on the back of the display unit of the Acurite thermometer.
- For tower models, you’ll find the reset button on the back near the bottom.
- For console models, look on the back right side.
- For the Acurite Access, the reset button is inside the battery compartment.
Consult your specific user manual if you have trouble finding the reset button.
Press and Hold the Reset Button
Use a pointed tool like a paperclip to press the reset button. Hold the button down continuously for 3 seconds.
When resetting the Acurite Access, press and hold the button for about 5-7 seconds.
Don’t tap the button, make sure to hold it down for the recommended time to complete the reset.
Remove Batteries
After holding the reset button, remove the batteries from the Acurite thermometer display unit. Wait about 10-15 seconds before reinserting the batteries.
This briefly cuts power to the thermometer to complete the reset.
Check for Success
Replace the batteries and turn the thermometer display back on. It should display dashes while acquiring signals from the sensors.
If the outdoor sensor reading shows “–“, press the reset button on the BACK of the outdoor sensor to sync it.
Once connected, the base station will display the indoor and outdoor temperatures. The successful reset is now complete.
Reset Tips and Notes
Follow these tips when resetting an Acurite indoor thermometer:
- Press the reset button with a pointed tool, not your finger, for best results.
- Hold the button continuously for at least 3-5 seconds to fully reset the thermometer.
- Remove batteries from both the display unit and any detached outdoor sensors.
- Perform reset when experiencing inaccurate readings or no readings at all.
- Try a reset if outdoor sensors fail to synchronize with the display.

Troubleshooting Common Acurite Thermometer Problems
In addition to a reset, the following troubleshooting tips may help resolve common Acurite thermometer issues:
Inaccurate temperature readings
- Make sure both units are placed out of direct sunlight and away from heat/AC vents or drafty areas for proper readings.
- Allow up to 30 minutes for both sensors to fully adjust to new locations for accurate temps.
- Clean dust off sensors and make sure they are not blocked.
- Try replacing old batteries in both units with new alkaline batteries.
No outdoor sensor readings
- Press reset button on both sensors to resync them and wait 15 minutes.
- Ensure outdoor sensor is within 330 ft range and free from obstructions.
- Insert a brand new set of batteries in the outdoor sensor.
- If still no reading, press and hold reset button for 15 seconds to factory reset the sensor.
- Verify the channel dial inside the sensor matches the base station.
Display screen problems
- Check for low batteries and corrosion in the battery compartment.
- Clean battery contacts with rubbing alcohol and coat with non-conductive grease.
- A full reset may be required if screen displays incorrect characters.
Wireless signal loss
- Relocate the display unit and/or outdoor sensor to improve wireless transmission.
- Install mounting brackets to elevate outdoor sensor above obstructions.

FAQs About Resetting an Acurite Thermometer
How often should the Acurite thermometer be reset?
It’s a good idea to reset the Acurite every 2-3 months. Some users find resetting monthly can maintain accuracy. Only reset when troubleshooting issues – frequent resets are not required for normal operation.
Does resetting delete the minimum/maximum records?
No, resetting will not clear the daily minimum and maximum temperature records. It solely clears any erroneous readings or errors.
Can I reset if the thermometer is working fine?
You can safely reset the Acurite even when its working normally. However, this isn’t necessary unless you experience inaccurate readings or wireless connection issues.
Does a reset work if the outdoor sensor stopped transmitting?
Yes, pressing the reset button on both the indoor unit and outdoor sensor can often get a failed outdoor sensor to successfully reconnect and transmit data again after a reset.
Why does my Acurite show dashes after a reset?
Displaying dashed lines immediately after a reset is normal behavior. It indicates the thermometer is acquiring signals from the sensors. It should display temperatures again within a few minutes once fully synchronized.
How do I factory reset my Acurite?
You don’t need to factory reset these thermometers. Simply press and release the small reset button to reset the Acurite. Holding for 15+ seconds is not recommended and can corrupt calibration.
Can I use a paperclip to press the reset button?
Yes, a paperclip or other pointed non-metallic tool is perfect for firmly pressing the recessed reset buttons on Acurite thermometers when resetting them.
Why does my Acurite say Hi or Lo after resetting?
Seeing Hi, Lo, or HI/Lo on the display typically indicates the temperature is outside the measurable range. Try resetting the outdoor sensor and moving it out of direct sunlight to resolve this.
Conclusion
Resetting an Acurite indoor outdoor thermometer is a quick and easy first step to troubleshoot inaccurate temperature readings, wireless connection issues, and other problems.
