There could be 2 x reasons why this has happened
Either interference from an out side source is blocking your signals or the radio reciever in the units has gone faulty
This i very had to identify without changing the circuit board or listening on 433mhz with a radio scanner
Interference can be caused by any new electrical equipment in the building , Tempary Traffic Lights , Radio masts , Police , Fire , Ambulance stations etc etc
