If your garage door opener repair is not working properly, there are a few things you can do to try and fix the problem. First, check to see if the batteries in the remote are working. If they are not, replace them and see if that fixes the problem. If the batteries are working, make sure that the transmitter and receiver are properly aligned. If they are not, realign them and see if that fixes the problem. If the transmitter and receiver are aligned properly, check to see if there is something blocking the signal between them. If there is, remove the obstruction and see if that fixes the problem. If none of these things fix the problem, you may need to call a professional to come and take a look at your garage door opener.
