We bought a new home a few weeks ago and the remotes were hit and miss and did not always open the door. We replaced the battery, bought new remotes, still hit and miss. We would press the button 20 times and it would work maybe 3 times. Lowes was having a sale so we bought a chamerlin and got them to install it. They installed yesterday and when I got home last night the same thing is happening! Now, I am not an idot and know how a garage should be working however I think it is strange that BOTH machines are doing the same thing. They even installed the new sensors with the new machine. I have a call in to the instalation team and she thinks it is the sensor and wants us to call her and she will walk us through correcting it. This seems very strange that both units would do the same thing. Thoughts?
