HiThanks for the message.One of the batteries is not holding a charge, or it is damaged. If you have replaced the batteries, cleaned the battery compartment and are still getting no response to the doorbell, then it is worth considering changing the transmitter. If you have bought the latest wireless doorbell, then this is a simple process. You will need to pull out the old transmitter and insert the new one, it is as simple as that. If you have the wireless doorbell without a transmitter, then you will have to replace the main doorbell system. You will need to ask the manufacturer for replacement parts or information about a local supplier.
HiThere are lots of different models of wireless doorbells, and most of them have a transmitter and a receiver. It is really important that you look at the specifications of the system you have bought to check that they can send a strong wireless signal. You will also need to check the range of your system. Your doorbell transmitter should be able to cover at least 50 metres, and be at least 3 metres high. If the system is not able to cover the desired range, then it will be unable to work properly. If you have changed the batteries and it is still not working, then you should consider changing the receiver, or replacing the doorbell.Kind regardsAWH
HiThanks for getting in touch.If the batteries are new, and the system still does not work, then there may be a wiring issue. It is worth taking the doorbell apart and checking that all the wiring is in good condition.
