Liftmaster 1245 led blinks five time but door will not open

If you have a 315MHZ LiftMaster Garage door opener do the following:
Follow the purple wire (Antenna) up and you will see a square purple button.
Press and hold the square purple button for ten seconds until the amber led goes out.
Press and release the purple button one time (The amber led will come on solid).
Press and hold the button on the garage door opener remote control for two seconds (The light bulb on the garage door opener will blink and you will hear a click sound the amber led will go off).
to program the wireless keypad do the following:
Press and release the purple button one time (The amber led will come on solid).
Enter a four digit code into the keypad then press and hold the enter button for two seconds (The light bulb on the garage door opener will blink and you will hear a click sound the amber led will go off).

If the main light is blinking 10 times check your door sensors. Make sure they are pointed at one another and the small light on each one is lit and not flickering. Tweak them a bit. If you cannot get both lights to come on you have a bad sensor.

5 FLASHES IS USUALLY AN RPM SENSOR PROBLEM - GO TO LIFTMASTER.COM AND DOWNLOAD THE MANUAL - VERY GOOD DIAGNOSTICS IN THE BOOK

HOPE THIS HELPS

The LED blinking 3 times is the code for "Door control or wire shorted."

If it blinks 5 times and doesn't move AT ALL. The circuit board is bed.

Hope this helps

That code is RPM sensor or motor overload. When the RPM sensor goes bad the motor will still run for a short time. If the motor has been run several cycles it will turn off on the thermal overload and won't reset for about 15 minutes. The resetting is automatic. Is your door stuck in the open position?

tell listmaster. maybe new board is n/g

Five flashes indicates possible RPM sensor failure. First try unplugging opener for five minutes and plug back in. If it still does not work replace RPM sensor.

are eyes aligned and led on for each eye. where is trolley. wedged in up position. take out safety bolt and see if it will run. need more info to help more like model,age,etc
