I’ve had this dusk to dawn sensor working fine for some time ( years ) and today the red LED started to flash, so I changed the batteries as I have done many times before. However this time the red LED continues to flash, and the sensor does not turn the associated switch on or off. I have pressed the start button as the manual suggest but that produces no change. I have checked the battery voltage and it is 3.1 volts for the pair when in the sensor.
Any further suggestions would be welcome.
