Just put new batteries in both units but can't get the oudoor temp to show - what have ee done wrong?

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.

remove all batteries, bring the two units together and put the batteries in the base unit first, then the outdoor unit; they should sync within 2-3 minutes. Once they have exchanged temp and humidity once, you can separate them. Good luck.

an "EE" code means you have an open thermistor. "EC" is a extended compressor run code. typically with the 424 if the thermistors are good, as in no "EE" codes you probably have a refrigerant leak. 73UE is the temperature at the upper evaporator thermistor. 73LE is the temp at the lower evaporator thermistor, 73up is the upper compartment temp and 73lo is the lower compartment temp. the unit probably has a leak in the evaporator/heat exchanger assemblies and needs a refrigeraton system rebuild

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.

Sometimes the RF frequency from the outside transmitter loses contact with the clock's frequency ( it has happened to me only twice in 6 years ), and then the outside temp will not show. Simple solution to fix this is: Take down the outside transmitter and the internally mounted clock. Remove batteries from both. Wait about 10 mts. First install batteries in the transmitter, then after about 30 seconds, install batteries in the clock. In about 5 mts, you will find the clock showing the external temp like before.

take rool out and throw away that should fix it

From what i have seen EE means overload warning, I looked on the website your scale has a lifetime warrenty on it i would recomend calling customer service @ For Customer Service: 800-289-0944 before messing around with anything.

PLEASE make sure that your monitor is over your artery, there should be a small plastic part that will tell you that that is where it need to hit your artery for the EE to go away. IF that does not work, and I am sure it will, but I have heard, never even experienced it, but have heard that a LOW battery can trigger it, but again, in 15 years, never heard of it..... Guy... OH, let me know if you need any more help, glad to be here for you...

I think it has something to do with the temp sense circuit of the control board, my fedders ac model a6d24e7a-e says the same thing if i bypass the temp sensing bulb with a resistor the unit will run but i do not have any way of controlling the temp, if i can find out that type of thermistor is being used i might be able to put a new one in and i will post it here

What is the name and model number of your unit?
