Remote that gives outside temp does not work put in new batteries, still does not work!

Make sure that the channel (1,2,3) agrees between the sender and base. You might try a different channel due to interference. double check batteries. Then -- remove batteries from remote and base. Then put batteries in remote first (should be next to base) then insert batteries in the base. Be sure channel is in agreement between the units. Sync can take a minute or longer.

my unit tells me to insert fresh batteries into the outside sending unit first. then insert new batteries into the inside receiving unit. after the outside temperature shows up, then can reset my inside unit's time, choose F or C and
switch channels. please try changing channels if your
outside temp doesn't show. you can do both units in the house then put one outside after they work properly.

Alkaline batteries will not work below freezing in the outside temperature sensor. Buy Lithium batteries for the outside sensor unit alkaline are okay for the inside unit.

That makes scence, you have to have an outside temperature probe. If it is wireless it also needs batteries. Check manual for more details.

You have to push some buttons to tell the MAIN unit to scan, then put battery into the REMOTE, set channel, and hit reset through a little hole. And the MAIN should see it.

hello emar... check to be sure that the little wire antenna is hanging down from the back of the garage door opener motor. Then check it. If it still won't work from outside, install new batteries.

If that doesn't do it, remove the new batteries and use the eraser end of a common pencil to clean the battery contacts inside the remote. then reinstall the new batteries and try it again.

I had same problem. Take all batteries out of both units. Put the batteries in the remote sensor FIRST. Then put batteries in the main unit. Within five minutes, they will link up. Problem solved!

sound to be in heat modenow. If you are after the cool mode, then if you have a cool setting and a heat temp setting, Lower the heat to almost off and set the cool setting to 74 degrees. See if the outside coils get warm. Make sure you are off manualo and n auto. If it runs, give it some time and the tenp of the outside coil will rise and the inside will get cold. Food Luck

I've had a similar problem with another model, an Oregon Scientific Model IWA-80055 Wireless Thermo Clock, in which when I replaced the batteries in the remote sensor, the clock would not read the temperature from the remote sensor.
I found it fairly consistent to solve this by taking a battery out of place in the clock and putting it back in.  Unfortunately this also messed up the clock's time and date.  This is also in the instructions catalogue for the device, check and see if yours gives a similar solution.

Also,

If you have lost the outside temperature on the clock display after replacing the transmitter battery then do the following:

1. Make sure you have good batteries installed in the remote transmitter
2. Remove the batteries from the main clock and keep them out until the clock display disappers.
3. Re-install the batteries in the clock.
4. Wait until the display returns and includes the outside temperature display as well.
5. Set the clock again for current time/date etc.
6. Bingo. You are in business.
