Although soccerobsession is correct by saying Sears doesnt splash some huge warning on the garage door openers box stating this product may not work in your neighborhood because someone may have plugged in a digital clock radio, it DOES say on every remote control right next to the FCC ID # THIS DEVICE COMPLIES WITH PART 15 OF THE FCC RULES. Before I give you the how to, for you DIYers and which products you will need to use to accomplish this,I have to say I completely agree with Sears tech support guys who said the FCC mandates which products can interfere or more importantly cannot interfere with other RF products. In reply to soccerobsessions rant, there IS a fix for the interference problems on liftmaster, chamberlain, and craftsmen garage door openers on the 315 mhz frequency. I am ripping out my Craftsman and switching to a Genie which operates at 390 mhz. According to Genie, they only have rf interference with openers installed close to major airports, and they in fact manufacture dual frequency equipment to defeat this problem, on the rare occasion that it occurs. you can take it back to Sears or wherever you bought the Chamberlain, and buy a different brand. You would then find anything on the circuit which causes the problem. You can find out what is interfering with your remotes by either disconnecting anything with a remote or motion sensor, or by turning off a circuit breaker one at a time until you find which circuit has the problem. I have spoken to several techs about LED lighting, including Sears' own technician, all whom who have never heard of any interference caused by LED lights. Both Sears and Chamberlain refused to fix, refused top assist, and suggested that I throw out the birdbath. Chamberlain blamed the water fountain manufacturer, and suggested that I call them and have them fix their manufatcturing defect!. I contacted Chamberlain, and they also said the interference is caused by RF interference, with no explanation as to why they do not advise the consumer in any publication with their openers. I was able to isolate the problem directly to the LED lights (NOT the transformer for the fountain, and not the water pump)! After refusing to assist, Sears advised that Chamberlain makes their garage door openers. This past month I recently installed a water fountain bird bath with six small LED lights in a front garden, which I found again shut down my remotes AND my home links in my cars. I took off and threw out a motion sensor on my light and initially fixed the problem. Both Sears and Chamberlain also will not and have not put this information in any instruction manual, nor do they have any fix. They will not post it in their stores, and they do not advise their sales people. They will not post the possibility of rf interference with their openers on a web site or any advertisement. They insist that the frequncy change was mandated by the FCC. Sears refuses to fix, but acknowledged that the problem is caused by rf interference with their 315 mhz frequency use by motion sensors, etc. Had and still have the same problem where the remotes refuse to work unless directly underneath the opener.
