Back to Garage Door Question List Remote Control IssuesThe remote control on my garage door opener no longer works? How can I test it?Most modern garage door openers have a coding system so that someone else with a remote can't easily get your door open with their remote... or so your garage door doesn't open when the neighbor lets the dog out! This is accomplished with a series of tiny switches inside the remote control and on the opener. See if positions of these "dip" switches on the receiver and the remote are the same... if not change them to match. There are some openers that self code... that is, instead of having code switches on the opener, it reads the signal from the remote and remembers the code. This is a little complicated to explain, and different manufacturers have different setup procedures, so dig out the manual and follow the instructions. Without specialized electronic testing equipment, there is no way to tell whether the remote or the receiver is defective. You are left with two options. If the opener is a common one... Stanley, Genie, or Craftsman... you should be able to purchase a replacement for the remote control. Be sure to purchase one that is compatible with your unit. Bring the model number and serial number with you when ordering the replacement.
