Only when it's very cold outside my garage door

When it's cold outside my garage door will close only by pressing and holding the hard wired control (vs remote). When its very very cold, this needs to be done repeatedly.

It sounds like the cold is affecting the door sensors. They each have a small light that should be lit and not flickering and they must be pointed at one another for the lights to work. It could be the cold is warping whatever they are attached to or it could be a case that they just fail when it is cold. Some sleuthing may be called for.

Garage door won't close when it's cold outside


Control board has thermal issue. Bad solder joint that contracts when cold could be the culprit. Take out board and carefully resolder every ****** connection on board.

The bottom door is not closing right. I can slide


Normal 0 MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman";} The lower hinge on each door may have a door closing cam. It raises the door up ¼ inch when opening and this assist in closing the door. If it’s wore out and doesn’t work the door may not seal and the gasket can be damaged. Watch the operation of the door to see if it rises up when opened.

Leave the door shut and let the magnetic gasket hold the door in place. Put something between the bottom of the door and the floor to hold it in case it slips.
Remove the bracket holding the pin and hinge assembly taking note of order of removal of parts. Slide new cams on. You probably need two.
COLD GARAGE
Not all refrigerators are insulated the same and not all condensers are in the same place. Your cold control is monitoring the temperature of the refrigerator section and is designed to turn off the compressor to keep things from freezing in that section. If it stays cold long enough outside in your garage the cold control thinks its cold enough and won't turn the compressor on. A makeshift closet to hold a little heat the unit generates will probably help.

Try increasing the 'down force'. You will find the control on the rear of the motor unit near where all those white wires go. Increase it about 1/4 turn and try.

Liftmaster 1/2 - Will not close


What usually happens is a sensor gets bumped so that they no longer are pointed at one another. They must be for the light on the second sensor to come on. Tweak them and see if you can get the light to come on. If you can't you either have bad wiring going to that sensor or the sensor itself has quit working.

Garage door shuts down, need to press reset to get it to work


On the side of the opener you will find the down limit control. Turn this a bit in the opposite direction of the arrow printed on the cover. You will probably have to tweak it a bit to get it just right.
