PROBLEM REVIEW: In total truth, there have been very few returns of the Teiber/Craftmade Doorbell Touch Buttons. And by a "few," I mean maybe three out of literally thousands and thousands being sold. Upon extensive and critical examination of the returned devices, we were not able to detect any electrical problems whatsoever. What this now becomes is a simple, but solvable, mystery and not a manufacturing or design defect: CLUE #1: One customer stated that he tried one particular model of our touch doorbell button and it worked for a few days and stopped so he again bought another thinking the unit was defective. CLUE #2: Same problem, the touch feature was not working on the second unit either. SOLUTION: More than likely, he was mounting the touch button on a metallic surface like aluminum siding or on an aluminum or metal door frame surface. What is happening is that the touch device's sensing circuitry is trying to compensate for this additional metallic mass as part of the device's metal housing and the internal computer chip cannot add in such infinite metallic mass. The remedy is to mount the touch device on an insulator of thin wood or plastic, or simply contact Craftmade for a thicker mounting gasket that is being upgraded to avoid such an occurrence from happening. ALTERNATE SOLUTION: If the installer did not use the included plastic insulating anchors when mounting to a metallic backing surface, the metal screws will contact the metal backing and again try to add that metal mass to the housing's surface. The internal computer chip cannot compensate for such infinite metal mass if that metal is conducted to the device's metal touch housing. Additionally, make sure not to forget to use the insulating gasket that goes on the backside of the device's housing.
PROBLEM #2 REVIEW: A second touch button was returned wherein the customer stated that "wind" or the "sun" hitting the Teiber/Craftmade Doorbell Touch Button would set it off from time to time. It testing, we subjected the returned device to over 150 degree hair dryer wind and heat for hours on end with absolutely no ghost false rings. Not even one! SOLUTION: What we suspect is the metal backing issue once again as explained above. If in question, allow the device to hang freely from the connecting wires as a temporary test. No false rings should occur. Just make sure the dwelling's metal backing siding or door framing is not directly in contact with the Craftmade doorbell touch button's metal housing or the metal screws either for that matter.
The patent-pending Craftmade LED Illuminated Doorbell Touch Button has been designed to compensate for temperature changes as well as changes in mass as in a situation of accumulating rain, ice, snow or even a lizard coming in contact with the device's HUMAN (only) touch sensing circuitry. NO false rings should ever occur, not even in power outages or brownouts.
For a "No Problem" Installation of Teiber and Craftmade LED Illuminated Doorbell Touch Buttons
The only time that you might encounter a "false ring" issue with these great Craftmade LED Illuminated Touch Doorbell Buttons is if they are installed incorrectly. The onboard circuitry actually contains a small computer chip (PIC) that constantly corrects for varying conditions like ice, snow and driving rain landing on the touch surface, which is actually the entire button's housing. Even if a small creature such as a lizard crawls across it, no problem. It won't ring. Now, the only way things can go haywire is if the metal touch housing is directly screwed to a metal backing surface (like aluminum siding or a metal door frame) without using the insulated anchor screws and/or insulating gasket which are both included. Direct metal to metal contact will force the onboard computer to try to make ALL of your metal backing become part of the touch area! This unintended, huge metal surface area will then overload the computer chip's ability to compensate for increased masses (like the crawling lizard which is certainly much smaller than your metal-siding clad house). Thus, the elements (direct sunlight, high heat, wind, etc.) can possibly cause a false ring. Craftmade is currently introducing a thicker gasket to help solve this rare "false ring" mounting problem on metal surfaces. In the meantime, use a temporary wood or plastic spacer shim if needed.
Once installed, the four internal LED's should light up rather brightly. If they are not illuminated or are dim, there is most likely a deficient voltage problem coming from the house's doorbell transformer. Using a VOM multimeter, the voltage should read close to 16 volts AC at the button location. The problem could be a significant voltage drop to the button location in that the wire run is too long from the transformer or the wires are too thin from the original installation when the house was built. One solution would be to check that the transformer is indeed a 16 Volt AC transformer and not a 10 Volt one. Another solution would be to up the transformer to a larger 30 VA rated output one. (That's 30 Volt-Amps, not 30 volts!). It's also possible that you only have a 5 VA rated transformer instead of a standard 10 VA one.
*** WARNING! ELECTRICIANS ONLY: Then carefully check the transformer itself at its location. (Remember, that's 120 Volts AC input to the transformer!). If the voltage is too low or exceeds 16 volts on the output side, shut off the power to the transformer before doing any more work on the doorbell system. Replace the transformer with a new one, readily available at most home centers. ***
