Allister company has led in manufacturing garage door openers and radio controls for homes and gate industries. Their products are long-lasting when you maintain them well, and they have great professional technicians for any repairs. However, if having any problems with your door opener, first diagnose it and try some DIY tips as explained below.

Why is My Allister Garage Door Opener not Working

When working on your garage door opener, always unplug it from the main outlet or switch off the circuit breaker. Carry out the following tests to diagnose the cause of the issue.

• The problem may be with the remote. If the door fails to respond when using the remote, try another one to check whether the issue is with the first remote.  If this fails, use the wall switch push button and see if it responds.
• If the wall switch fails, you may have a faulty receiver or interference from other radio signals.
• To note, if there is interference while using the remote close to the opener, it activates, but when you move further away, it fails to start.
• Ensure you connect the power cord to a working power outlet. Confirm if the outlet is working by using another functional appliance.
•  The motor start capacitor may be faulty- be keen to note any burnt electrical odor and replace it with a new one.
• There may be obstacles in the doorway. Check the track and clear any obstructions or dirt on it.
• Broken torsion springs- if you hear some sounds like fireworks, the issue may be broken torsion spring.
• Have a locked door- if you hear the garage door opener work, but there is no movement, check the manual lock.

How to Adjust an Allister Garage Door Opener

Adjusting your garage door opener helps protect you and your family from being hurt as the door moves. If your door requires too much force to reverse or fails to reverse at all then, you should adjust the opener controls.  If you notice this issue in your door opener’s auto-reverse, use these steps to adjust it.

Tools Needed

• Steep ladder
• Screwdriver
• Locate the openers controls

Use a step ladder to reach the main part of the opener’s motor.

• Adjust the opener settings

Using the screwdriver, turn the knob counterclockwise one-quarter to decrease the amount of force needed to reverse the door. Again, to increase the amount of energy, turn the knob clockwise.

• Re-test the auto-reverse function and, if necessary, repeat the steps above until the opener gets fully adjusted.
• If the garage door fails to reverse correctly, ask the service provider for repair immediately.

Where is the Learn Button on an Allister Garage Door Opener

You can find the “Learn” button on your garage door opener above the receiver cable that dangles from the engine head; it may also be beneath a light cover. The “Learn” control has either green, red/orange, purple, or yellow colors.

How to Diagnose a Garage Door Opener
