Why won't lift master garagedoor opener work in cold weather

Colder weather solidifies the grease to add extra friction on the moving door in the track. Increase the downward close pressure. Its a screw on the motor box. There are 2 sets of screws one for open and close pressure the other set for close and open distance

There are many reasons that I can speculate on for this happening but they would all be my best guess! The First would be is that their is an issue with the logic board /replacing this part can run from $45 up to $80 .The board has a antenna that runs to the outside of the machine that receives the signal from your remote...The transmitter. This board is a direct link to making your machine operate..Now lets take a look at some cheaper alternative fixes that we can try before hand to do a process of elimination...Make shure the batteries in your remote are fresh and strong...if that's ok then the next thing I would say is your remote old? I have found that in keypads and remotes that the contacts do wear out when they become old from pressing the buttons thousand of times over the years so to keep that in mind you can try replacing the remote...The cost of the remotes run between $29 and $40 on average ,but before we think about that lets keep thinking about process of elimination! Next the antenna that comes from the logic board sometimes does not receive a strong enough signal from your remote because you may have a garage that is brickfaced and has no windows on the garage door...this causes your transmitter (remote ) to send a weak signal to your opener and you would have to be fairly close to the opener to make it operate that's because the signal becomes weaker penetrating the steel or wooden door you may have ...windows allow the signal to be stronger. So here is another thing you can try to help boost the signal to the machine...The antenna that hangs from your garage door opener is made from an aluminum wire that is coated and is usually about 10" inches long , I have found success by extending the wire another foot with the same type aluminum wire ...you can just splice them together and let them hang from the machine! These are the things I would try to do first before spending money on remotes or boards but if your machine is a older model like 20 years old a lot of the parts become obsolete so by saying that it may be time to invest in a new opener! There are many different scenarios that I can dream up but without knowing the model and year of your opener..if you have a universal remote or the original / if you have windows on your garage door or not I would just be guessing at why you are having this problem! You can also call Liftmaster technical support and give them the model# and year of manufacture info which you can find behind the light cover on your machine and they may be able to help you ...if you have a newer machine within a year old ,you may be covered under a warranty! I hope I was able to give you a little insight into some of the things that may be causing your problem , Good luck Sincerely Glenn
