75077 outdoor sensor not working

I've been having issues with my outdoor sensor stopping working. It starts by the outdoor temp not updating, always reading 69 degrees. Back in August after troubleshooting it was determined I needed a new outdoor sensor so I bought one and it worked for a bit, but now I"m having the same issue.

I've tried
-hard reset (removing all batteries, placing in outdoor unit first and leaving them together to sync), the signal finder is animated for a while but it never picks up a temp
-changing the switch to a new letter (ensuring same on both units) with all batteries removed and replacing them
-changing the batteries in the outdoor unit (I've verified the batteries work in other devices)

The red light on the outdoor sensor never lights up, so it seems like my "new" outdoor sensor is already dead. I keep this on a covered porch, it's never gotten wet (though I do live in FL so it's quite humid) and is never exposed to direct sunlight

Hello Me10Lee83,

Make sure you are doing the 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.

What type of construction material is the house made of? How far is the sensor from the display? What is the name brand of the batteries you are using? Where on the porch is the sensor mounted?
