Raynor prints the name Admiral II on the side of the operator. The manuals we have posted are for the 8550WRGD and 8550RGD. These are ceiling-mount rail openers. They use a yellow Learn button (Security+ 2.0). An 893MAX (Raynor 893RGX) remote, 878MAX keypad, or L932M keychain will program to that button. The WRGD book is the Wi-Fi version. Not every Admiral II model or manual is shown here. We post the manuals we have. Older or uncommon units may not be listed.

Shared features

We don’t sell opener circuit boards. They typically aren’t the issue when experiencing problems with the operator. Go through the troubleshooting steps in the operator manual and if you still believe that you need a logic board, email store@garagedoorzone.com and we can point you to the correct part number.
