I have the same problem and I thought it was the temp but it has gotten worse. Unplugging or waiting a few minutes I can usually get it to open or close at least partially. I have made several small adjustment and paid for a service which all seem to help but not fix the problem. Anyone else have the same problem with 1/2 hp lift master?

It sounds like a problem with the infrared safety beams, either they are not working, are misaligned (someone might have kicked/bumped into one), or I even had one that didn't work because there was too many cobwebs/dust covering one of the lenses.

The light by the learn button may be sending a diagnostic code. See if it is flashing a number of times, pausing and then repeating. Count the flashes. Is your door stuck in the open posititon?

If your sensors are not pointed at one another the light on one of them will go out. Tweak them a bit. If you cannot get the light to come on then your sensors are bad.

If you have only one remote it is impossible to tell if it is bad or if the receiver which is part of the logic board has failed.

The garage door does not stay down.Comes back up with lights flashing fast.The sensors are clear and the pressure has been set.


If when the door reverses the main lights flashes 10 times it is a door sensor problem. Nothing else will cause this. Make sure the light on each sensor is lit and not flickering ever so slightly. The flickering can sometimes be difficult to see.

Door won't open


Unfortunately storms do bad things so door openers sometimes. It has most likely gotten to your logic board. You can remove that board and look for burnt or missing traces of the print. Random flashing of that LED is normal.

Replace the logic board. I have seen this problem in the field. More often than not it's due to power surge or lightning strike.
