To test a limit switch on a garage door, open the door and disconnect the opener. Manually raise the door to the fully open position and adjust the open limit switch screws until the door stops when it is fully open. Then, close the door and adjust the close limit switch screws until the door stops when it is fully closed.

Reconnect the opener and test the door.

If your garage door isn’t opening or closing properly, one of the first things you should check is the limit switch. The limit switch is a safety feature that tells the garage door opener when to stop running. Over time, limit switches can become worn out or damaged, which can cause them to malfunction.

Testing a limit switch is a relatively simple process. First, locate the limit switch on your garage door opener. It will be a small box with two wires coming out of it.

Once you’ve found the limit switch, disconnect the two wires. Next, use a multimeter to test for continuity between the two wires. If the multimeter beeps, that means the limit switch is working properly.

If there is no continuity, the limit switch will need to be replaced.
