Model 00754WB not displaying Outdoor temperature, though all troubleshooting steps have been applied

I purchased my Model 00754WB unit December 1, 2016 at Walmart.  It was working good until recently.

I noticed the outdoor temperature was staying at 42 degrees for a few days in a row.  I normally only look at the unit once or twice a day, and unfortunately spring is slow to arrive.

Yesterday the temperatures finally got into the 60's for several hours and the display still showed 42.  The outdoor unit was still flashing.  It is mounted under a protected area of a deck.

I took the unit indoors and tested both the lithium batteries and they were only 20% power.  The indor unit alkaline batteries were also bad.  Therefore I read the manual, and replaced with new batteries in the order described.  The indoor has three new Duracell alkaline, and the outdoor has two Eveready Lithium batteries.  The setting for both units was "C".

The indoor unit will only display time and indoor temperature. Outdoor shows only two dashes.  I left the units next to each other overnight, with same result.

Then I tried setting both units to "A" with same result, then tried setting both to "B".  Nothing has helped the indoor unit "find" the outdoor unit.  I also tried the reset procedure with a paperclip on the display unit.

What can be done to get the unit working?  I really miss having the outdoor temperature working.

Hello Mark,
Our first suggestion would be to remove the EverReady batteries from the sensor. EverReady is not one of our recommended brands and we only recommend using lithium batteries in temperatures -4° and below. Please verify you are using the battery recommendations and try the troubleshooting steps listed below. 


•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.

I did not reply because it took a while to troubleshoot based on the suggestions given.

I did every step in this recommendation, including using NEW Duracell Alkaline batteries in both units.  Expiration date is March 2027. 

The outdoor unit is not reporting any temperature to the display.

I checked the batteries on a high quality tester.  They show 100% charge.  They are not rechargeable, they are Alkaline "copper top".

I tried the procedure above, setting both units to "C" - did not work.

Then set both to "A" - did not work

Then set both to "B" - did not work.

For each test I let both units sit side by side for 1 hour.

Nothing has worked.  

I bought the unit December 1, 2016 and this problem started sometime between Dec 9, 2017 (the day I moved into the new house, the outdoor unit was working) and in early March, 2018.

The outdoor sensor's red light will blink, but nothing is reported to the base unit.  In other words, "the lights are on, but nobody's home".

The unit has always been properly cared for, neither unit has been dropped, or damaged in any way.

I suppose that I am simply unlucky because the warranty has run out.  

Is it reasonable to expect this item to last only 13-15 months?
