Neverending searches for the elusive hyper desirable architectural enhancement that will stun visitors often ends with a high style craftsman doorbell that is individually artisan made. Through the decades the prominent and visible door chime has gradually decreased in quality to the point where all the typical chimes that you find locally at the big box store are disturbingly made of plastic and have an electronically generated ring tone that that sounds more like what you would expect from a toddler's play toy rather than something you would want to use to showcase your upper end vintage home. This is all a fancy way of saying that a craftsman doorbell should exude quality and class.
Prior to considering a craftsman doorbell it is a good idea to ask yourself if the current system is functioning normally. You should have a strong ring and not some feeble intermittent tone. If you are not able to pass this test successfully then you'll need to isolate the problem, which is either going to be in the wiring, the transformer, the doorbell button, or the chime mechanism. Usually the transformer is fine which is a good thing since it is often difficult to find. You can tell if it is working by testing the available voltage from the wires connecting to the chime mechanism. Or if you have access to the transformer you can test the output side which should be around sixteen volts or so. Doorbell buttons are located outdoors and often get oxidized contacts just due to being exposed to the weather. Often fixing that scenario is as simple as just replacing the button part or sandpapering the wires that connect to the button. But the most common problem that causes malfunctions in the doorbell system is a faulty chime mechanism. These can be bumped and damaged fairly easily if you aren't careful so it is best to treat them with some respect so they can provide years of reliable service.
