Background: I was frustrated with how frequently I was replacing the incandescent light bulbs in my garage door opener, so I invested in two new IKEA LED bulbs. All of my family members began noticing that their remotes could open the door from down the block, but wouldn't close it unless they were nearly in the garage.
Project: I replaced the batteries in the remotes, replaced both safety sensors on the sides of the door, realigned them perfectly, adjusted the up and down forced and travel limits only to find it didn't help.
Solution: After reading an earlier post about a flickering fluorescent bulb in the garage, I immediately went out and replaced both IKEA bulbs with conventional incandescent bulbs and the problem is solved! The LED bulbs when lit were interfering with the remote signal. DO USE LED BULBS IN YOUR GARAGE DOOR OPENER.
I hope this is helpful. Thank you.
