I replaced batteries, no luck, I bought a new remote, programmed it and no luck, the wall unit works fine opening and closing. Is it the remote sensors? Where are they aand how do I test/fix them? Any other suggestions?
Make sure the light in the wall unit is not blinking. If it is press and hold the button with the lock icon for 3 seconds. The sensors will not prevent the remote from working. Make sure you got the correct remote for your opener. It is easy to get the wrong one. The model number for your opener is on the opposite end of where all those white wires go and starts with 139. Use it when you need parts.
