Does Your Garage Door Limit Switch Need Resetting?

If you’re having trouble opening or closing your garage door, it might be an issue with the limit switch. Understanding what a limit switch is and how it functions can help you diagnose the issue and determine whether a quick fix is needed or if you need professional repair.

In this blog, the garage door experts at Absolute Insulation explore some of the most common problems with limit switches and offer some simple solutions to keep things running smoothly until a professional technician arrives.

What Is a Limit Switch & What Does It Do?

A limit switch is a critical part of your garage door opener system. It’s a mechanical switch that signals your opener when the door has reached its limit, or end, of travel in either the open or closed direction. This ensures that your garage door stops moving when it should, preventing potential damage or safety hazards.

Typically, there are two main types of limit switches in a garage door system: one that detects when the door is fully closed and another that detects when it’s fully open. These are essential for the safe and efficient operation of your garage door.

3 Common Limit Switch Issues & How To Fix Them

A limit switch that isn’t working properly can be more than an inconvenience. But there are some things homeowners can try to help resolve the problem on their own.

Here are some common limit switch problems you can troubleshoot. But remember: Always use caution and consider calling a technician for a thorough inspection and repair.

1. The Garage Door Won’t Open Completely

If your garage door only opens partially or stops before reaching the fully open position, there may be an issue with the limit switch. Try these steps to fix the problem:

• Check for obstructions: Make sure there are no objects or debris blocking the garage door’s path.
• Inspect the safety sensors: Dust or misalignment of safety sensors can trigger the limit switch to stop the door early. Clean and align them as needed.
• Adjust the limit switch: Consult your garage door opener’s manual to find instructions on adjusting the limit switch settings. Typically, adjusting the limit switch one turn for every 3 inches of adjustment is accurate. Once you’ve adjusted the limit switch, you should retest and calibrate again, if needed.

2. The Garage Door Won’t Close Completely

Conversely, if your garage door refuses to close all the way, you can try these steps to troubleshoot on your own:

First, check for obstructions and inspect the safety sensors as you would if the door won’t open all the way.

Then, adjust the down limit. It’s best if you check your opener’s operation manual to learn how to adjust for your particular model. However, typically one counterclockwise turn per every 3 inches that the door needs to go further is recommended. You may need to adjust and test several times to get it right.

3. The Garage Door Closes, Then Opens Again

If your garage door closes part-way but then reverses and opens again, here’s what you can do:

• Examine the tracks: Inspect the garage door tracks for any bends or obstructions.
• Lubricate moving parts: Apply lubricant to the rollers, hinges and springs to reduce friction.
• Check for Loose Wires: Inspect the wires connecting the limit switch and the opener for any loose or damaged connections.

If none of these steps solve the problem, adjust the down limit switch by one full clockwise turn. Then test and readjust as you need for the door to stay closed.
