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.
Best regards, --W/D--

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.
