Liftmaster garage door opener
A few days ago, my aunt had to use the wall button to lower her garage
door. Both remotes would raise it but not lower it. Now, after a few days of using the wall button, she finds that the remotes will again close it. The same thing happened last year. She thinks it may be the humidity. What could it be? |

I would look at the receiver, just inside the back cover. http://www.gatehousesupplies.com/Pho...e=10-41AS050R1 Item 10 on page 34 of the Owners Manual: http://www.liftmaster.com/consumerwe...px?modelId=853 Sounds like you may have a hairline crack that flexes under temperature. You could take it apart and carefully reflow every connection that appears likely, or pay the 60 bux and replace the receiver or pay 200 bux and replace the whole unit. http://www.acehardwareoutlet.com/%28...px?SKU=5056767 --Winston |

The floor mounted safety sensor beam may be impeded. Clean the lenses. Additionally when the lens gets cloudy if the sunlight can hit the lens directly it can mask the beam. |

The 'wall button' will close the door, so it isn't sensing an obstruction. The wall button is suppose to override the sensors and close the door. |
