| By troubleshooting, I found my receiver logic assembly is defective in my Craftsman Door Opener model 139.53992.
How do I replace it? I saw the pictorial in my owner manual,I need assistance in removing the faulty logic board. |

| It simply unplugs after removing the screws and cover. Be sure to unplug the opener from the outlet first. |
