The safety interlock sensor is blocked or not working - those are the sensors at the bottom of the door that check for blockages.

Cannot program new garage code


You are missing a step. It sounds like you have a genie intellicode black wireless keyless entry unit. The final step is to program to the opener. When you open halfway and press the prog and 8 keys, youve unlearned the unit from the opener. Lets start over. Complete the previous steps and then finally, press the code or learn button on the opener. There is a red LED light next to it which will flash after pressing it. Within 30 seconds, type your new code and press the up/down or enter button on the keypad. Then press the up/down or enter button a second time. Programming is complete!

If the LED is flashing rapidly when the button on the remote is not pressed you have interference from something. Check for old remotes stored in a drawer somewhere or some new electric item nearby. Start unplugging things until that rapid flashing stops.

Liftmaster 1/2 hp won't open


Turn the gears again by hand like you did and lower the door a couple feet. Now find the 'up limit' on the side of the motor unit and using a small screwdriver turn this about 3 turns in the opposite direction of the arrow printed on the cover. Now you can go ahead and operate the door.

Craftsman Garage Opener Clicks only and LED blinking 5 times


first off, hitting extra button on remote would not do anything. Is door up or down/ where is trolley that attaches to chain, by door or motor. Is is jamned against a bolt. Try a paper clip and jump from white to read terminal. Does it work. Does light bulb blink 10 times. I ignore the diagnostic lights and go by symptons. Give more info.
