QUESTION: Will the LiftMaster 823LM Remote Light Switch work with my Craftsman Assurelink Opener, model 139.3043? by LANCE R S 6/30/2015
ANSWER: Yes...I have a Craftsman Assurelink with 3 of these switches and it works fine. by Kenneth M a
ANSWER: Hi Lance,<br />The Chamberlin MyQ LiftMaster light switch and garage door are connected to the Internet via the Gateway device that connects to your home router. <br />I am not familiar with your Assurelink Opener model so I don't know if it is comparable with the LiftMaster Gateway. That may be a question for Chamberlin to answer. In as much as Sears buys from major manufactures your unit may be built by by Chamberlin and may be compatible. Also, check with Sears and see if there is an Internet connection for your Opener.<br />Another key point is the MyQ App. is needed to remotely operated the Garage Door, Lights, and any other Chamberlin MyQ products.<br /><br />SIDE BAR NOTE: I am very pleased with Garage Door Opener & Light Switches that I tell them and show them how I can turn my house lights on & off from any location & check on the status of the garage door as well as open & close it. by Charles F a
QUESTION: Can the switch be used for a pool light? by John E 3/21/2015
ANSWER: Yes, If the switch itself stays indoors or in a rainproof enclosure, I see no difference between a pool light and my application which is a driveway light outside. <br /><br />The only thing you have to make sure is that your light is within the stated wattage of the switch. by Thomas M a
ANSWER: I would assume if it works like a regular single pole light switch and it is indoor, the rule of thumb it will replace a regular light switch, make sure you check your wattage ratings. by Rick E a
QUESTION: does anyone make switch like this in "THREE-WAY"???? by jerry l 1/9/2015
ANSWER: Unfortunately, do not know of any manufacturer, at this time, that makes this switch in a "THREE-WAY" configuration. by Charles F a
QUESTION: What happens if you connect the green wire from the switch to the white neutral electrical wires. The white eventually finds a path to ground. Is it AC that intereferes with the radio. I remember some deviceses using power wires as antennae.<br />Back to my question. What happens if you tie the green wire to the white ones? by Gary A 11/30/2014
ANSWER: Beyond the safety implications and the violations of the electrical code, I'm honestly not sure. It may work, but it's still a really bad idea.<br /><br />If your electrical box isn't properly grounded and/or there's no ground wire in the cable leading to your switch, it's really better to resolve that than to short the safety ground to the neutral. One of the points of the safety ground is to provide a low-resistance path to ground in the unlikely event that neutral becomes electrified so that you'll trip a breaker instead of killing someone. by Owen D a
ANSWER: My experience is the GREEN wire must be connected directly to ground wire only for the switch will not operate. <br /><br />After the correct connection is achieved there is a one to two minute delay before the switch becomes operational.<br /><br />The switch has absolutely met my expectations. The MyQ App meets the advertised capabilities. I can turn the lights ON and OFF from anywhere and verify that I closed the garage door after leaving the house. These features are great. by Charles F a
ANSWER: You are correct that in a normal installation, the white wire and the grounds wire in the Romeo find their way back to the same bus bar in the fuse box. However by doing so, you are defeating a safety feature of your home wiring. I would not do what you are suggesting and I would look for a proper ground. by Thomas M a
ANSWER: That is a question for the manufacturer, other than that I would follow the directions it has an antenna. by Rick E a
ANSWER: If you connect the green and white together you possibly live the unit/switch therefore creating a serious shock when touched, and if the unit/switch internal parts fail the ground or green wire connected is the only thing that may save you or your home. The green wire connected to ground is probably the most important wire why chance it!!!! The switch already has a great antenna with great reception, it is the yellow wire which goes right into the wall. by Joe C a
ANSWER: Creates a National Electrical Code violation. Not a good idea. by Jeff N a
