Raynor prints the name Sentinel on the side of the operator. The manual we have posted is for the 85503RGD. This is a ceiling-mount belt-drive Wi-Fi opener with an integrated camera, battery backup, and a yellow Learn button. An L993M visor remote, L932M keychain, or L979M keypad will program to that button. Not every Sentinel model or manual is shown here. We post the manuals we have. Older or uncommon units may not be listed.

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.
