Question about liftmaster Electrical Supplies
After fixing my Daughters garage door, aligning up, straightening track & placing rollers back into track, & re-tensioning springs, why does the chain tensioner jamb up against the drives gear at the motor end, and does not return when under load. I had to replace the sheer pin on the drive gear for the hall sensor, is this sensor timed in to the relation of where the position of the chain is, because every time we start it with the remote it travels in the same direction, does not return?

SOURCE: Garage door won't stay closed
Check the down limit:
If the light bulb(s) on your operator are on the front and/or back, the limit adjustment screw is on the left side of the operator (looking from the back of the operator and facing the garage door).. If the lights are on the sides of the operator then the limit adjustment screw is on the left side (looking from the back of the operator and facing the garage door)

Just fixed this problem tonight. Had the 5 blink/flash thing. Opened it up and saw that the motor wasn't spinning so it wasn't a bad rpm sensor. Jumped the red to black and then the blue to black to verify motor worked. At that point assumed it was the logic board not telling the motor to start, but I could hear the click of the relay. Pulled the logic board out and noticed a solder joint that had failed directly behind one of the relays. Resoldered that joint and the garage door opener worked again like a dream. Hope that helps someone else.

SOURCE: I have a problem with
I have the same problem. Door does not open or close when press the push button and/or transmitter. The light flashes 5 times. Manually open or close the door is ok. On the manual troubleshoot, it says it's either the opener is overheated or it's on vocation mode. I don't know how to switch of vocation mode. Is it possible the thermal sensor is broken?
Can someone help?

Is your house being hit by lightning? If so, there is nothing you can do.
If not, it could be a spike in the electrical service as well, I think. Try installing a high rated surge protector on the plug end. Some even have a guarantee that if the equipment protected gets damaged, they will pay for repair.
Let me know,
