Red/orange will connect w/ one opener, but not the other (same model)

The remote will only connect to one of our garage door openers. They are Craftsman 1/2 hp and the same model.

Hi,
Do you have existing remotes that works with the “not connecting” doors?
If so, can you please send me the working remote’s part number?

This is to make sure the opener circuit is good, and help us to identify the compatibility.

Thanks.

The remote is Craftsman model # 139.30498. It also works from in my GMC truck remote.

Understood, according to your remote control’s manual https://c.shld.net/assets/docs/spin_prod_845152512.pdf

It works with both 315Mhz (Purple) and 390Mhz (Orange) learn button openers.

My guess is, maybe your other opener is using 315Mhz system…

Thanks and let me know if you have other questions.
