The garage door won't close and the lights flash

The most common reasons the garage door won't close and the lights on the garage door opener flash 10 times are:

  • The safety reversing sensors are not connected, obstructed or misaligned.
  • There is a short or broken wire for the safety reversing sensors.
  • The safety reversing sensors are faulty.

Locate the safety reversing sensors on both sides of your garage door.

First, you’ll need to make sure nothing is blocking the sensors. Once you’ve removed any obstructions, the LEDs in both sensors should glow steady. Try closing the garage door with your remote control. If the door closes, great, you’re done!

If you’ve determined the sensors are not blocked and your door still won’t close, click on the image that best describes your situation.

If the forces are set too light, door travel may be interrupted by nuisance reversals in the down direction and stops in the up direction.

Without a properly installed safety reversal system, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing garage door.

  • Too much force on garage door will interfere with proper operation of safety reversal system.
  • NEVER increase force beyond minimum amount required to close garage door.
  • NEVER use force adjustments to compensate for a binding or sticking garage door.
  • If one control (force or travel limits) is adjusted, the other control may also need adjustment.
  • After ANY adjustments are made, the safety reversal system MUST be tested. Door MUST reverse on contact with 1-1/2" high (3.8 cm) object (or 2x4 laid flat) on floor.

Why does the remote control only close the door?

The most common reason your remote control will not open the door is a weak or low battery.

What is radio frequency (RF) interference and how does it affect my garage door opener?

Your garage door opener has an internal receiver that listens for the signal from your remote control. If there is an electronic device within range of your garage door opener that is sending out a stronger signal, this interferes with the garage door opener’s ability to hear your remote control signal. Examples of things that may cause interference: Battery chargers, radios, and fluorescent lights. To find the source of the interference, narrow it down through process of elimination. Locate the circuit breakers in your house. Turn ALL the circuit breakers OFF except the circuit breaker for the garage door opener. Unplug all electronic devices in the garage except for the garage door opener.

Use the remote control and activate the garage door opener. Did the garage door open?

Yes
No

If the range improves this indicates the device causing the interference does not have power, therefore, the device is not in the area of the GARAGE.

Turn ONE circuit breaker ON. Test your remote control. If the range improves this indicates the device causing the interference does not have power, therefore, the device is not in the area of the KITCHEN.

Turn another circuit breaker ON. Test your remote control. Continue to turn ON one circuit breaker at a time until you find the source of the interference.

SOLUTION

When the source of the interference has been determined the problem can be fixed in one of the following ways:

  • 1) Leave the device unplugged.
  • 2) Replace or repair the device.
  • 3) Purchase an alternate frequency kit and change the frequency of the garage door opener.
