None Of My Handsets Are Working
Test the power point that the opener is plugged into to ensure there is power. Then test the opener by pushing the open/close button on the opener. If the opener doesn’t work we recommend calling for a service.
If the opener works then you may need to check for interference from other radio transmitting devices in the area such as wireless security systems, baby monitors, and doorbells. Disable any of these devices you locate and test the opener button again.
If the handsets still won’t open the garage after performing these tests we recommend you have them tested as they may have a fault and need replacing.
