If your AcuRite Iris™ (5-in-1) sensor is losing connection to the display unit and/or AcuRite Access™, the low battery icon is often present on the display, or the sensor is going through batteries too quickly, please review the troubleshooting suggestions below. We expect recommended batteries to last between 12-24 months. If your batteries are not lasting at least one year, we would recommend the following troubleshooting steps.
You would want to ensure the following first:
- Verify that the old batteries have lost all/most of their power by using a voltmeter or testing in other devices.
- Verify that you are about to use a fresh set of batteries. The battery expiration date should be at least 6 years out. Batteries can lose 3% of their power or more every year in storage.
- Use standard alkaline batteries from a high-quality brand (or lithium batteries in the sensor when the temperature is below -4ºF/-20ºC). We do not recommend using heavy-duty or rechargeable batteries.
Once you have verified that you are using recommended batteries, please perform one of the following resets:
Please follow the steps carefully as the order is crucial to the success of the reset.
If a hard reset does not correct the issue, (Ex. the batteries drain within a few weeks or months, the sensor still loses connection with the display and/or AcuRite Access™, or the low battery icon reappears.) please use the following link to verify if your outdoor sensor is compatible with a replacement part that we offer.
If your outdoor sensor is considered "compatible", please proceed with the steps below:
To help us analyze what may be causing the issue you described and the next steps needed, you will need to get the OUTDOOR sensor:
- Please remove the 4 screws holding the sensor together and separate the 2 halves.
- Once separated, in the bottom half, locate the black/red wires that are connected to a skinny green or black board-this is the temperature and humidity board.
- Remove this board from the slot and inspect the part for signs of damage or corrosion. You may see a green or white buildup or some discoloration of the components.
- Please also remove the black cover and inspect the main circuit board for any signs of damage or corrosion.
- You do not need to remove the screws that are holding the mainboard into the sensor.
Here are some example photos:
If your Temperature and Humidity Sensor board appears to be damaged or corroded, we recommend replacing this part. Here is a link to this replacement part:
If your outdoor sensor is considered "incompatible" with the replacement part, a replacement Iris™ (5-in-1) sensor is recommended. Here is a link to purchase a replacement Iris™ (5-in-1) sensor for your convenience:
