Question about liftmaster Chamberlain Garage Door Opener Transmitter 300MC

Open Question

I just bought a house that has a two car garage with two Wayne Dalton garage door openers - the label inside each one says Chamberlain Model 310WD. I have reprogrammed the remote for door #1 and the two wireless keypads outside the garage doors, each with different codes. Now when I press one remote, both doors open/close! The openers have yellow learn buttons, and no visible DIP switches. Help!

Hello, W/D here.

Change out the battery in the remote, and then reprogram. It sounds like this may be the cause of failure.

Try reprograming the opener to each remote, if this doesn't work then the command/radio module in the opener is damaged and needs to be replaced. Hopefully you can find one or you will have to replace the whole garage door opener. Good luck.
