Hi Wireless doorbells or chimes The transmitter and receiver portion of these units are virtually identical to those of garage door operators. See the relevant sections on those units for problems with activation.
The bell or chimes portion may be either an electromechanical type - a coil forming an electromagnet which pulls in a plunger to strike a gong or bell. See the section: " Electromechanical doorbells and chimes". Others are fully electronic synthesizing an appropriate tone, series of tones, or even a complete tune on demand. Repair of the electronics is beyond the scope of this document. However, there are several simple things that can be done: * Check for dead batteries and dirty battery contacts in both the pushbutton and chimes unit. * Confirm that the channel selection settings have not accidentally been changed on the pushbutton or chimes unit. Flick each switch back and forth (where switches are used) just to make sure they are firmly seated. * Check for improper programming or program loss due to a power failure (if AC operated) on units that are more sophisticated than a personal computer. Doorbell rings on its own * For mechanical chimes, this is almost certainly an intermittent short circuit in the button wiring or a defective button. First check or replace the outside pushbutton switches as this is the most likely location due to environment and small multilegged creatures. * For electronics chimes, the problem could either be in the transmitter(s) or chimes unit or due to external interference. Someone in your vicinity could have the model also set to the default code (which is probably what you have, correct?). First, remove the batteries or kill power to all transmitters and wait see if the problem still occurs. - If it does, either the chimes unit is defective or there is an external source of interference. - If it now behaves, try each one individually to identify the culprit. In some cases, a low battery could produce these symptoms as well. Old garage door operator guts for wireless chime Don't toss the electronic remains of that old garage door operator. It would probably be possible to use it as the basis for a wireless doorbell. Instead of starting the motor, use its output to enable an electronic chime or buzzer. The RF transmitter and receiver for a wireless chime is virtually identical to that of a typical garage door operator.
