Why is the outdoor temperature flashing on my AcuRite 00826 Thermometer?
- KKaren GloverAug 3, 2025
Flashing outdoor temperature on your AcuRite Thermometer usually indicates wireless interference. To resolve this: 1. Bring both the sensor and display unit indoors and remove the batteries. 2. Reinstall the battery in the outdoor sensor, then in the display unit. 3. Let the units sit close to each other for about 20 minutes to establish a strong connection. Also, ensure the units are within 165 ft (50 m) of each other and at least 3 feet (.9 m) away from electronics like TVs or microwaves. Use standard alkaline batteries (or lithium batteries in the sensor if the temperature is below -4ºF/-20ºC). Note that it may take up to 20 minutes for the units to synchronize after replacing the batteries.
