Hi Rachel , Can you find a model number on the door controller unit it will help us to search for a possible idea on the settings side of the solution to your unwanted problem.
Another possible solution may be to use a UPS on the controller. This stands for uninterruptable power supply. However long prolonged power failures may drain the UPS battery but it would work for short power interruptions (time depends on the standby power drain of your door controller and the VA rating of the UPS) and brown outs to the power lines. These are used on computers normally so a search on the internet for UPS or take a visit to a computer shop and they would source or carry a UPS device.

Look at the LED light next to the
SMART/LEARN button on rear of the motor unit. You may need to remove
a light lens cover in order to see it. If the light is flashing
rapidly this means you have a stuck button on one of your remote
controls. Take the batteries out of each remote control. When you
remove the batteries from the bad remote, the light will stop
flashing. This remote needs to be replaced.
If one of your neighbors remote
controls is inadvertently programmed into your receiver, you door
will open when their remote is activated. If this happens you will
need to clear out your receiver and reprogram your remote controls.
Press and hold the smart/learn button for 6 seconds or until you see
the small LED light near the button turn itself off. If the above
steps have been followed and the symptoms continue, there may be an
electronic short in either the wall control button or the receiver
logic board. In this case, remove the wall control wires from
terminals 1 and 2 on the motor unit. Should the symptoms persist
after the wires are removed, replace the receiver logic board. If the
symptoms stop with the wall control wires removed from the motor
unit, replace the wall control button, and the wires leading to the
wall control button.

I had the same problem and fixed it by greasing the chain and roller chamber and spraying silicone on the springs. Works beatifully now AND my wife is happy.

I had the same problem. Although it appeared to be the logic board, on mine it actually was the connectors between the logic board and the power supply board.
There are 2 connections on the logic board. One white connector with wires going to the main unit, and another set of connectors that plug directly into the smaller circuit board that holds the step-down transformer (120vac - 22vac). These pins were not making good connection between the boards. I simply bent the pins slightly so they would make better contact on the logic board and have not had a problem since. This must be a weak point on these door openers. Purchasing a new logic board would work too, as the connectors are newer and tighter.

Make sure the door springs on the door are ok.Unhook the opener from the track by pulling the red handle rope on the track,make sure the door moves up and down freely.There is a up-force adjustment on the end of the opener that the small wires run to,you will see 2 slotted adjuster screws,find the one labeled up force,turn it clockwise a little bit(1/16th of a turn).Also there is a plastic gear inside the case that gets dry,unplug the opener,remove the 8 screws that hold the case on and lube it with a lithium grease,see if it is worn badly while you have the case off.

I have a feeling your neighbor operated their door opener when you were programming your new clicker. Try erasing the memory of your opener and then program the clicker again making sure your neighbors do not operate theirs at the same time. To erase the memory hold the smart/learn button in for 10 seconds.
