how do cold temps affect older automatic garage door openers?
I have two that are over 20 years old and they work just fine in colt temps.
cold temps really don't affect the openers as much as it does the garage door, which in turns makes the opener work harder. I usually try to tell my customers to make sure that they oil (not grease or any type of spray grease because it gets stiffer as the temp gets colder) with an oil can and regular motor oil. oil all the rollers pulley wheels and or bearings twice a year, right before winter and right after winter because the cold temps make everything on the door work harder. disconnect your door from your opener and see how it works buy hand, it should be rather easy to lift - not heavy. if so, it may need some tension added to the springs. with the door unhooked oil all rollers and pulley wheels. open and close your door 5-6 times to work in the oil. give them all another little shot of oil. open/close your door couple more times. your door should be running smoothly now. check for worn out roller and pulley wheels. if bad replace them. hook your door back up to the opener and see how it works now. the rule of thumb - the easier the door works the longer the opener will last.
