😃 Tip 2) Check the batteries.

If the remote works fine but the wall unit fails to engage the opener, first consider the power source. Some opener wall control units are battery operated while others tie into your home’s electrical wiring or simply plug into the wall. Test the batteries, if applicable, to see if that fixes the problem. Otherwise, quickly examine the plug or wiring to see if you can locate visible damage such as scorched, exposed or broken wires.
