Marantec garage door opener keypad not working

There are a couple of reasons why your wireless keyless entry will stop working. Here s how to diagnose and troubleshoot the issues.

Dead batteries

If the batteries are over a year old or the keypad buttons are flashing for 10 seconds, you should replace them with triple(AAA) batteries.

Defective keypad.

The keypad typically stops working after using it for a year. The elements such as extreme temperature, humidity, and liquid spills can cause the keypad to malfunction. Look for cracks, signs of water damage, and broken keys. If you cannot fix it, replace the keypad.

Frayed or disconnected wires

Most keypad issues result from a loose contact between the keys and wires. Remove the keyless entry from the wall and open its back cover using a screwdriver. Inspect the internal wires and reattach the wires making sure they are secure. If any sire is short, you will have to replace the keypad.

Stuck keys

Dust, dirt, and grime can result in the buttons sticking to the pad. When the buttons become stuck, you have to clean the inside and outside of the keypad. Use a clean rag and some appliance cleaner to clean the outside, and then use a soft toothbrush to clean in between the buttons. You can also use compressed air to clean between the keys.

PIN code error

If the opener does not accept the PIN, you should first avoid entering it too many times as this can permanently damage the keypad. To fix the issue, clear the keypad memory and change the PIN to a new one. To clear the keypad memory, remove the keyless entry from the wall mounting place, remove the batteries, and press and hold the Enter button. Install the batteries, release the enter button, and the LED will flash for about 5 seconds.

Marantec garage door opener remote control is not working

If your garage door opener is receiving power and not responding to the remote control, there are several ways you can fix the issue. Here is a brief troubleshooting guide for the Marantec remote control.

1. Check the batteries. Depleted batteries are the most common reason for remote control not working. If you have not replaced the batteries in over six months, you should replace them with the CR2032, 3 Volt battery. Make sure you use the correct batteries; otherwise, they won’t work or won’t last long.
2. The garage door opener is in Vacation/Lock Mode. The Vacation Mode locks out all remote control transmitters from operating the garage door. To determine if the Lock Mode is active, check if the button on the wall control is flashing. If it is, press and hold the Lock button on the wall control for about 3 seconds, and the big button will give a read steady light to show the opener is out of Lock Mode.
3. Radio interference could be blocking the remote control signal from reaching the garage door opener. Check for new electrical appliances, radio, speakers, light bulbs, remote-controlled toys, irrigation systems which can all cause signal interference. Contact the Marantac customer car and ask for a change in frequency.
4. Check the modular receiver on top of the motorhead with an antenna wire protruding from it. Disconnect it and reconnect it, check for dirt and clean the contacts. Check for physical damages like bends and warping or lose connection. If a power surge hit the modular, you would have to replace it.  Make sure you get one compatible with your garage door opener model.
5. Reprogram the garage door opener to the remote control transmitter.

Why does my garage door keep stopping while closing?

When the garage door keeps stopping while closing, there are a few reasons that can explain this problem:

1. Check for any obstruction blocking the photo eye sensors. Remove any pets, snow, objects from the garage doorway. Dirt and dust can also build upon the photosensors and block the beam. Use a damp clean cloth to wipe the lenses on both sensors.
2. Check for misalignment. You can tell proper alignment when both the red and green LED lights are glowing steadily. If the green light on the transmitter sensor is flashing, the sensors are out of alignment and need readjusting.
3. Ensure the safety sensors are correctly connected. If the LED lights on the photo eye sensors are not on, it means there is an interrupted connection. Check the terminal cord connecting to the powerhead, disconnect it and reconnect it again securely. Ensure the white wire from the sensor attaches to terminal 1 and the stripped wire connects to terminal 2.
4. If the problem persists, check for any broken or short wires. Pest and rodents can chew up the wires, and power surges can burn the wires to cause connection problems. Use a multitester to test for current in all the wires and replace them if necessary.

Why is my Marantec garage door opener blinking?

If the opener light is blinking and the garage door is not closing, it means that the safety sensors are misaligned or obstructed. The safety sensors are a safety feature in modern garage door openers that forces the garage door to reverse during closing or refuse to close when they detect motion or an object on its path. To stop the light from flashing, you have to remove the obstruction or realign the safety sensors.

How to realign the photo eye sensors

The photo-eyes sensors maintain an invisible, unbroken light beam between each other, and when this beam is blocked, the garage door automatically refuses to close. Here is how to readjust the sensors.

• Since the door will not close, pull the emergency release cord to allow you to close the door manually. Then, close the garage door to ensure proper visibility of the light beam.
• If the opener is on power and the green light flashes, it means the sensors are out of alignment.
• Loosen the screws that hold the mounting brackets in place with a screwdriver.
• If there were no objects on the path, clean the photo lenses with a clean rag. When dirt accumulates on the lenses, it will behave as if there is motion on the doorway.
• Move the sensors until the green light on the transmitter sensor lights up steadily to indicate proper alignment.
• Hold the photo-eye sensor in place and tighten the bracket screws.
• Return the garage door manually to the open position, make sure there are no objects on the doorway, and disengage the emergency release cord.
• Perform a safety test by placing a carton box to obstruct the beam, press the wall control button; if the alignment were successful, the garage door would not move. Remove the carton box, and the garage door should close completely.

Why is my garage door opener not working?

There are several reasons that can cause your garage opener not to close or open correctly. Here are some of the causes and their possible solutions.

The opener’s power source is disconnected.

Check if the opener has been unintentionally unplugged and reconnect it. Next, make sure the power outlet is working; test it by connecting another appliance. If the appliance does not work, replace the power outlet. If the power outlet is working, but there is no power, check the fuse box, look for any tripped circuits, and turn them on.

Photo-eye sensors are blocked or misaligned.

The photo eye sensors are usually about 4-6 inches off the ground that direct a beam of light across the garage doorway. When an object or dirt obstructs this beam on the lenses, the garage door will not work. Remove anything on the entrance and clean the lenses with a damp cloth.

If the green LED light on the sensor is flashing, the sensors are out of alignment. Loosen the sensors on the brackets, adjust their position until the red and green LEDs flash steadily, and then tighten the screws to hold the sensors in place.

Broken torsion springs

The torsion spring connects the cables that wind up when you activate the garage door opener. When the springs break, the garage door won’t work properly or won’t work at all. After about 10,000 complete cycles, the springs often wear out and break. Call a professional garage door technician to come to replace the springs.

The cables have disengaged.

Often when the torsion springs break, the cables also pop out as a result. Call a professional technician to fix the disengaged cable and torsion springs.

The garage door is in manual mode.

The Marantec garage door opener has an emergency release rope that you pull outwards to engage the manual mode and allow you to close and open the garage door manually. When you press the wall control button or the remote control button, the garage door opener won’t work. Return the emergency release cord to engage the garage door opener. Make sure the emergency release cord is in a place where you cannot easily accidentally engage it. It should be at least 6 feet from the ground.
