    Yestrday, my door wouldn't go up. I had to help it go up. If I disconnect the door, the chain moves. Maybe it cannot take the load or the motor need some maintenance?

    Press the button, goes up about 2 feet. Multiple tries eventually get the door to raise correctly.

I also had the same problem with a liftmaster garage door opener. The garage door stopped about two feet off the floor and would not open any further. I inspected the screw drive position where the door stopped and decided to use a lubricant like WD 40 to lube that area of the screw drive. After doing this the door starting working and as an added benefit the operation of the door became much quieter.

Problem solved!!! All the screw drive needed was some lubricant. I checked the operating manual for this opener and didnot find this solution there.

Take care,

this solved the problem I could not fix for 2 years. A little WD40 on the screw drive did the trick.

The garage door hums for a few seconds and then stops, the door won't go up or down.

Make sure the trolley isn't jammed against the bolt just in front of the motor.

Hi I have a Chamberlain garage door system. I use the remote to shut the door. The door goes down to a foot off the ground and goes back up again. I've tried for over an hour to get it to shut and it won't...

The motor has probably been shut off by the thermal protector. Wait 15 to 20 minutes and it will reset itself.

If when the door reverses and goes back up, the main light flashes 10 times it is a door sensor problem. 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.

Problems opening garage door on cold mornings

If you have used grease on any part of the door hardware or tracks you will have to clean it all off. The recommended lubricant for the hardware is silicon spray and nothing at all on the tracks. You can also increase the up force which you will find on the rear of the motor unit near all those white wires.

Craftsman - chain drive. now open won't travel more than 1 ft.

Sounds like you have a bad RPM sensor board. This is a small printed circuit board just in front of the motor.

My garage door opener doesnt close all the way.

The motor is probably either stalling because the door is too stiff, or you have a beam break detector that is being triggered when the door is halfway down.
