I have tried different settings and it still will not activate. If I remove the stack of cork like disc entirely, the icon umbrella will go off and the unit will function. Sensor is approx. 8 years old.
My Hunter rain sensor keeps showing the umbrella icon in the controller and it won't turn on. If I remove the stack of cork like material from the sensor, the umbrella icon goes out and the unit will function. Do I need a new sensor?
