How do I fix a weather clock that shows indoor temperature but no outdoor temperature?
Answer
Outdoor temperature on these clocks usually comes from a separate wireless sensor. Confirm the outdoor sensor is present, powered, and in range; then reset the main unit with fresh batteries and re-pair or re-set the clock and alarm buttons.
Before you start: stop right away if…
- Use the battery type the compartment marks; mixing old and new cells often causes weak outdoor reception.
Follow these steps
Locate the outdoor sensor
Check the original box and accessories for a small outdoor temperature sensor. If it is missing, the main clock usually cannot show outdoor temperature on its own.
You should see: You either find the sensor or confirm it was never kept with the clock.
Reset the main unit with fresh batteries
Remove the batteries from the main clock for about 10 minutes, install a fresh matching set, then use the SET and plus/minus controls to set time and date again.
You should see: The display restarts cleanly and time/date can be set without all segments stuck lit.
Power and place the outdoor sensor
Install fresh batteries in the outdoor sensor, place it within range outdoors or near an exterior wall as the manual suggests, and wait several minutes for the main unit to receive a reading.
You should see: The outdoor temperature field fills in with a reading instead of staying blank.
Set the alarm
Press ALARM or the alarm-set control, use the plus button to set the hour, press ALARM again for minutes, then press ALARM once more to finish and enable the alarm if needed.
You should see: The alarm time is stored and the alarm indicator shows it is set.

Extra tips
What to look for: A blank outdoor temperature field while time, date, and indoor temperature still work, and whether a separate outdoor sensor was included with the clock.
Before you change anything: Find the model number on the clock or original box if possible. Have fresh matching batteries for the main unit and the outdoor sensor. Keep the sensor within the range listed in the manual, usually with fewer walls between units. Do not force open sealed compartments beyond the battery covers.
