Chamberlain code 1-6
The door keeps drifting after it stops
Check this first, then a proThe door moves on after the opener stops it. Either the travel limits need setting again, or the door is out of balance.
What to do: You can set the travel limits again with the steps in your manual. If the door still drifts, it needs balancing, which means adjusting the springs: leave that to a pro.
Don’t lift or force the door by hand: if a spring is broken, the door can fall. Springs and cables are a pro’s job. DASMA
