Lift Master 'Pro-Line' malfunctions when it's cold
I have an older Lift Master "Pro-Line" 1/2hp GDO that will not close when you use the remote, but will close when you depress and hold down the wall button. This hapeens when it's cold, and not when it's warms. Is this an adjustment issue, or have the electronic board components changed value, thus requiring replacement? It's a Model #41a4252-6f. Also, how old do you think it is?
