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?

Maggie,
Check the led lights on the sensor eyes. They should be green and both lit up solid without blinking. If they are both lit up solid, it's not the sensors. I am assuming you are using the new remotes. For a new opener to work so intermittently, something is amiss. Without seeing the install, it's hard to say if everything was done properly. I install a lot of chamberlain openers and haven't had any problems with them working intermittently. Let us know what you find.

If both old and new openers react the same way(exactly the same???), I suspect it is not the openers. I would be investigating the power to the openers. Outlets with loose connections, loose connections in wiring upstream, etc.

can also be something in the garage or close by causing interference, like a fridge or something odd like that. Also, can be caused if you garage is a steel building.
If something is causing interference, chamberlain will have you unplug everything and try remotes. Then they will have you plug things back in, one by one to see what is causing the interference

This is a long shot and will sound weird, but try turning off all your lights and see if it makes a difference.

I had annoying remote issues with my cable and found it was due to a low wattage florescent bulb. I have several in the room but for some reason it's a specific one that causes the issue.

The remote will work very intermittently unless I turn off that light. Then it works perfect
