Why is My Garage Motor Beeping?

Feb 24, 2025

Are you noticing a beeping sound coming from your motor? Even if it doesn’t seem like a big deal, it can get annoying and might be a warning for more issues. There really are only two main reasons your motor would be beeping – issues with one or both sensors or your motor battery may need to be replaced soon. Luckily, you’ll likely be able to fix both issues yourself. We’ll walk you through the two most likely causes and a step by step guide to resolve each of them to help relieve the headaches.

Garage Door Sensor Issues

Occasionally your motor will beep when one or more sensors are blocked. Simply ensure both are free of blockage, where both have a clear line of sight to one another, and clean any debris from the sensor’s surface with a damp towel. It’s important to remember to never spray any chemicals directly onto the sensor as fluid can seep into the electrical components. 

Still Beeping? You likely have an electrical issue with one or both sensors and likely require a replacement. Luckily, we can take care of this! Give us a call today for a sensor replacement the same day you call us!

Low Motor Battery

Another culprit of your beeping motor could be a low battery. Replacement is usually very simple and won’t require a professional to replace. Most motors have a similar battery placement and we’ll walk you through a quick step by step guide on how to change out the battery. 

NOTE: To order a replacement battery, you can find your exact model on either the manufacturer’s website or Amazon.

  1. Disconnect the power
  2. Locate the cover that holds the battery (usually on the backside of the motor)
  3. Grab the appropriate Phillips or flat head screwdriver to remove the cover
  4. Carefully slide the battery out and disconnect the wires
  5. Grab your fresh battery, connect the appropriate positive/negative wires, and slide the battery in the same way as the one you removed
  6. Reattach the cover and reconnect the motor to the outlet

Following these steps should stop the beeping if a low battery was the issue. If the beeping continues after you checked/cleaned the sensors and replaced the battery, give us a call and we’d be happy to come out and assist.
