Hello Ron,

We would recommend doing a hard reset on both the display, and sensor. Please follow the steps below:



Perform a hard reset:

  1. Bring both the sensor and display unit indoors side by side.
  2. Remove batteries from the sensor.
  3. Remove batteries from the display unit and unplug the AC adapter (if applicable).
  4. Wait 1 minute to ensure any remaining battery power is discharged from both units. 
  5. Make sure the A-B-C ID code switch on both units match. 
    *Sometimes changing to a different ID code can help.
  6. Reinstall batteries in outdoor sensor first.
  7. Reinstall batteries in display unit second.
  8. Let the units sit within a couple feet of each other for 20 minutes to ensure a wireless signal is received. 
    * The display should receive the signal within several minutes. 
  9. After a connection has been established you may place the sensor outdoors.
    *If the signal connection fails after the units are separated try a new or different location for the display unit, the sensor or both.



If this does not correct the problem, please let us know. Thank you. Have a great day!

We are sorry you feel that way. We would be happy to go over the warranty options with you. Can you provide us with the model number of your product? If it is the sensor that is reading -40 specifically that model number please. Thank you. Enjoy your day!

Hello Peter,

We would recommend the hard reset steps below: 

Make sure the display and sensor are at least 3 feet away from electronics.  

Use a high quality alkaline battery such as Rayovac, Energizer, Duracell, or Kirkland.

Remove all the batteries from the display and sensor for about 5 minutes.

After the 5 minutes put the batteries back in the sensor looking for the red light to flash.

Then put the batteries back in the display and wait for the outdoor information to show. If it shows something other than -40 you can put it back outside. If it shows -40 we would need to start a warranty claim so please let us know if this corrects the problem. Thank you. Enjoy your day!

Hi, my credit cards are fine but the portal does not accept payment.  Is that because I have a USA delivery address and my credit card address is in New Zealand?  If that is the issue, how can I pay please as there is no PayPal option.

Hello Elmar,

In order to place an order you need to have a billing and shipping address in the United States or Canada. The order will not process without an address in one of those countries. We do not accept Pay Pal. Thank you. Enjoy your day!

I purchased the 02027A1 as a gift for Christmas and we are having the same problem. The sensor will read -40 outside no matter what we do. We tried the hard reset, we tried channels A, B and C. and Still -40. I emailed the support email address in the documentation as well, but received no response. The unit is less than 2 weeks old

Thanks. As stated in my email, we already tried the resets in your response. Because you took almost a week to respond, and your phone support appeared to be disconnected so I have already ordered a replacement sensor for $12 via Amazon.

Good call, eventually that's where you'd end up, replacing the sensor. -40 is how the MPU in the sensor interprets data coming from the actual temp sensor IC if that device fails or the interface is shorted out somehow, all zeroes coming in = -40.

The point is the unit is less than a month old. And didn't work out of the box.Accurote won't respond to warranty claims and their phone number for support appears to be disconnected, so I had to BUY the sensor. It isn't right to have to buy the part to make the item work.

My 5 in 1 sensor is reading -40 and shows model 0813. Is the sensor board replaceable in this unit and if so how?

Hello Mark,

We would recommend trying a hard reset on the weather station. If after the reset and you have had the sensor longer than one year, we would recommend the replacement temperature and humidity sensor however this is only compatible with certain models of the 5n1 sensor. If you want to provide us with the model number of your sensor we can confirm if the board would work. If it is a sensor that is not compatible with the board then you would need to replace the whole sensor.  The hard reset steps are below:

  1. Bring both the sensor and display unit indoors side by side.
  2. Remove batteries from the sensor.
  3. Remove batteries from the display unit and unplug the AC adapter (if applicable).
  4. Wait 1 minute to ensure any remaining battery power is discharged from both units. 
  5. Change the A-B-C channel, making sure the display and sensor match.
  6. Reinstall batteries in outdoor sensor first.
  7. Reinstall batteries in display unit second.
  8. Let the units sit within a couple feet of each other for 20 minutes to ensure a wireless signal is received. 
    * The display should receive the signal within several minutes. 
  9. After a connection has been established you may place the sensor outdoors.
    *If the signal connection fails after the units are separated try a new or different location for the display unit, the sensor or both.

Hello Jenny,

If the hard reset steps below do not correct the issue, we would recommend replacing the outdoor sensor. Please do the steps in the order they are listed.

You want the display and sensor to be at least 3 feet from electronics such as televisions, microwaves, computers & radios. Follow the battery guidelines below:

•Verify you are using fresh alkaline batteries or lithium batteries (when temperature is below -4oF/-20oC) 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.

Perform a hard reset:


1.Bring both the sensor and display unit indoors side by side.

2.Remove batteries from the sensor.

3.Remove batteries from the display unit and unplug the AC adapter (if applicable).

4.Wait 2 minutes to ensure any remaining battery power is discharged from both units.

5.Change the A-B-C Channel on both the display and sensor making sure they both match.

6.Reinstall batteries in outdoor sensor first.

7.Reinstall batteries in display unit second.

8.Let the units sit within a couple feet of each other for 30 minutes when comparing for accuracy
* The display should receive the signal within several minutes.

9.After a connection has been established you may place the sensor outdoors.
*If the signal connection fails after the units are separated try a new or different location for the display unit, the sensor or both.

I'm facing the same issue. All seems to be correct, except the outside temp of -40. I've tried to do the steps listed for few times but still nothing is changed. I have the 5-in-1 Weather Station with color display.
what should I do?

Hello Omer,

What is the model number of your outdoor sensor? Where was it purchased, and how long have you had it?  What is the name brand of batteries you are using in the sensor?  Where are you located?  Please do the reset steps in the order listed below:



You want the display and sensor to be at least 3 feet from electronics such as televisions, microwaves, computers & radios.  Follow the battery guidelines below:

•Verify you are using fresh alkaline batteries or lithium batteries (when temperature is below -4oF/-20oC) 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.

If you are following the battery guidelines perform the hard reset steps below:

1.Bring both the sensor and display unit indoors and position them side by side.

2.Remove all batteries from the sensor.

3.Remove all power from the display unit including the adapter (if applicable)

4.Wait 1 minute to ensure that any remaining battery power has discharged from both units.

5.Inside each battery compartment you'll find an A-B-C switch, change the channel to the next setting making sure they both match.

6.Reinstall batteries in outdoor sensor first.

7.Reinstall batteries (and/or connect AC adapter) in display last.

8.Let units sit within a couple feet of each other for 3 minutes to ensure a wireless signal is received.
*The display should receive the signal within several minutes.

9.After a connection has been established you may place the sensor outdoors.
 *If the signal connection fails after the units are separated try a new location for the display unit, the sensor or both.
