SENSOR BYPASS MODULE for liftmaster, Chamberlain, Craftsman garage door openers

first three photos should match the sensors you have now, last three are just like the module you will receive .

Custom module bypasses the sensors input and allows your door to close without any sensors attached. extremely stable and reliable but use cautiously, this is not a safety device and will not reverse a door while it's closing , or sense an obstruction. It is not UL325 approved and is for projects and testing purposes only, and must be used with the Liftmaster, Chamberlain, or Craftsman brand opener you already own. (replaces sensors like the ones shown in the listing photos) Hookup is simple enough that anyone can do it, and the module is so small it will go unnoticed. seller is not responsible for any damage, use at your own risk and do not use, until you understand that risk beforehand.

TO BE CLEAR, THIS IS NOT AN OPENER .... IT IS A CUSTOM MADE ACCESSORY THAT YOU INSTALL YOURSELF, ON AN OPENER WHICH YOU ALREADY OWN.

This product carries a DISCLAIMER so:

please confirm your brand of opener first, as I do not accept returns!!!!! may not be compatible with liftmaster ATS commercial operators

This is not compatible with “Genie or OverheadDoor” brand openers, only compatible with: liftmaster, sears craftsman, steel craft, chamberlain, and mastermechanic residential openers manufactured after 1999. (see my other listings for genie and overhead door

any returned modules that are found to be in working condition are subject to 50 % restock fee plus the return shipping charges .....i keep costs as low as possible and i simply dont have enough in it to pay shipping for someone who didnt bother to check first and wants me to pay for their mistake. Or even worse someone who buys one of these thinking it will magically repair a non functioning opener, then assumes they can return it as defective and expects to get a full refund for my time and money wasted.
