Question about Oregon Scientific Wireless IndoorOutdoor Thermometer with Atomic Clock Sync

Open Question

I have a RMR203HGA Temperature Humidity Station that all of a sudden won't communicate with the temp. sender. I changed the batteries in both units, put them next to each other, pushed the reset buttons, and did the search for a sensor steps and I still don't have an outdoor temp. reading. I have the sensor set on the #1 channel and the screen is showing that it is communicating with the sensor. The LED light on the sensor flashes every couple of minutes too. These units have been in use in the same location for 4-5 years with no issues. I need to know if I need to replace something or if it is fixable. Thanks for your help, Bob

The signals are not being received by the main unit. Try to reposition the unit or move it to a different location. Also make sure the antenna is in the clear and not next to any thing like a cordess phone or charger as these can make RF noise that can block or cover the needed signals.

Hello. Chances are that the battery contacts in the outdoor unit are corroded due to exposure to moisture. Do this. Remove the batteries and clean the battery contacts in the device using the eraser end of a common pencil. Then reinsert the batteries. If that doesn't do it, go to any auto parts store and get a can of electrical contact cleaning spray and repeat the above steps. J.

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.

SOURCE: the outdoor temp on the LED read out says LL.L.

attaching photos here for your TV problem--they show the board and where the part is, if you attempt the repair I will tell you best way to get at it.

Cap is pretty generic part--almost any TV repair shop or Tv parts dealer will have it: .47 microfarad @ 200vdc (original part should have "0474 200 " marked on it and that is the value I indicated in plain english.

see photos and if you want to attempt I will tell you how to get the box out and do it.

just above this spot are two multi-pin plugs that have been removed.

Removing the light box will allow access without having to disconnect much.

My 6yo NatGeo super weather station has quit transmitting outdoor temp & humidity info. The display is present and correct for all other categories. Changed batteries, no help. Any ideas?


  • Remove all batteries
  • Install batteries in transmitter and wait for it to begin sending data
  • Install batteries in receiver. You should see temperature and humidity displayed

I have a new weathr station and can not get the outside temp. to display what can I do?


I assume it is a wireless station. If so, there is a procedure to go through to get the temperature sender and the base station to sync up and work. You need to check your owners manual to get the exact procedure for your unit. On my station, I have to remove the battery from the base station, let it power up and within 5 minutes, install the battery in the remote station(s) (temperature, rain gauge, wind gauge, etc.). Also, you must keep the remote station within a certain range for the base to get a good signal. Probably 25 feet, but the owners manual will have the right number. Also, use new batteries.

Changed the batteries in both the transmitter and weather station. It doesn't show temperature on the transmitter or show temperature and humidity on weather station


In some of these weather stations, you have to install the batteries in the transmitter first and then the weather station within a certain time limit. Also, the weather station must be within a specified distance from the transmitter when replacing the batteries.

If you look on the weather station, there should be a make and model number. If you have that, you can visit the website (if there is one) and download an instruction booklet for your model.

My weather station is no longer recieving an outdoor temperature reading. The barometer is working fine, as is the indoor base station. Both were given new batteries at the same time, and the set up i


hi,


does the outside humidity working ?

if yes - the outside station is transmitting but the temperature sensor is faulty,
if no sensing is available from the outside station, it look like the outside station is faulty . (this is common because of extreme weather change.
notice that the pressure sense is done in the base station.

Auriol 4-LD3091 weather station will not pick up sensor


I had the same problem and gave up on the unit for a while, then I had another attempt and found this worked for me. Take the batteries out of both units (receiver and outside sender) then reinsert the batteries BUT put the batteries into the outside sender unit FIRST, this seems to make the difference as when you then put the batteries into the indoor base-station it detects the outside temperature signal immediately as it starts to set itself up .

1990 4runner not shifting properly when cold.


hello, first you need to make sure the engine gets to operating temperature, maybe the thermostat needs to be replaced, if after that it still has the same problem the temp sender could be the issue here. It is located on a housing in between the cylinder heads near the firewall where the heater hose connects. there are two temp sensors, one for the gauge on the dash and one for the computer.
The dash sensor has a single wire, the computer temp sensor has a connector with two wires and is a green connector.

Car runs great until it get about 180 degrees andthen shuts off let it cool off a lil bit its starts back up until it shuts off again why


I am thinking that perhaps the temperature sensor is reading wrong and therefore sending a message to the computer that the car is running too hot. This can happen, my VW presently reads 20 hotter on the guage than a heat gun records at the temp sensor location on the head. If you have access to a heat gun it might be a good idea to check out the actual temperature, but it probably won't hurt to change the sensor.

The other problem that occurs to me is the oil sending sensor. While a temperature sensor won't shut an engine down, the oil sender can. If it is reading a large drop in oil pressure it will shut the engine off. Since oil gets thinner as it gets hot, perhaps a defective sending unit is reading it as too low. Once the oil cools off, it would restart until the temperature gets too high again. I would think that upgrading to a heavier oil might cure the problem. I don't know what you are currently usung but certainly you could go to 10W30 or 10W40 without too much trouble, at least for a test. Hope this helps.

What is the proper setting for the Temp &Humidity?


Set the temp level at whatever point your home's temperature is now. Lower the humidity level to 35%. If you don't have an LED screen on your unit, set the manual control to maximum.This way, you will extract the maximum amount of humidity and make your home more comfortable.

Hope this helped you. Please let me know. Thanks.
