C-SP-315 not compatible with 3/4 HP Craftsman Garage Door Opener

Asstated, our C-SP-315 remotes are not linking up with the 3/4 Craftsman Garage opener. I have tried all butons (A-D) and none work. Please advise

Hi David,
Sorry for the trouble, would you please send me your opener’s model number?
So I can check, thanks.

Model # 2245 has orange learn button but C-SP 315 will not work.

Name= Ron

According to compatibility charts below
The model 2245 is using Security+ 390Mhz technology (red/orange button).

So you will need to check our C-SP-390 model instead.
Because C-SP-315 is for Purple button 315Mhz.

Thank you.
